A Charge controllers
Operating a solar panel system with a battery bank without a charge controller is simply unsafe. A good model can significantly increase the battery’s lifespan while also enhancing the overall security of your system. For smaller PV systems, such as those used in portable, RV, boat, or similar applications, we advise using 40 amp solar charge controllers.
The capabilities of a 40 amp charge controller
As its name implies, this critical component regulates the charging process. The following features are typical of a 40 amp solar charge controller:
- Protecting the battery from overcharging by regulating the voltage from the solar array
- Preventing overcharging and deep discharge
- Protecting from reverse current. Fires can start if electricity flows uncontrollably from batteries to panels at night
- Checking the health of the battery bank. A charge controller can be used to monitor the battery’s health and connected loads
Reasons to use a 40 amp charge controller
A large solar panel setup will overload a 40 amp charge controller. You should go with it if your project is medium to small – about a few 200 W solar panels. There is a more exact way to figure out if a 40 amp charge controller is what you need. In order to do that, you will need to divide the wattage of your panels by the voltage of your battery bank.
In order to charge a 12 V battery from four 100 W solar panels, for instance, you’ll need a charge controller with a capacity of 33.33 A (400 / 12 = 33.33). Here, a charge controller capable of handling 40 amps would be more than adequate.
Picking the best 40 amp charge controller
Whether to go with pulse-width modulation (PWM) or maximum power point tracking (MPPT) is one of the most important decisions to be made when selecting a charge controller.
It would be less expensive to use a 40 amp PWM solar charge controller. In addition, because they are less complex, these controllers have a longer lifespan. A PWM charge controller should last between ten and twenty years. The longevity and low cost, however, come at the expense of efficiency. Using a 40 amp PWM solar charge controller would limit your ability to customize the charging process and give you only 75–80% efficiency. Additionally, when the voltages of the panels and batteries are mismatched, this type of controller loses too much energy.
If it uses MPPT technology, a 40 amp solar charge controller costs more. In return, you have greater control over the charging process and an increased efficiency of up to 99%. It depends on the manufacturer, but these controllers typically last between 10 and 15 years.

Review
For the sake of everyone’s wallets, I almost hoped the Victron wouldn’t be my favorite. But it was.
Out of the box, I found the Victron to have the most features and be the easiest to use. It’s about as “plug and play” as it gets.
Bluetooth is built in to all the models in the Victron SmartSolar MPPT product line. Once the Victron is installed, you can use the free VictronConnect mobile app to monitor and customize your system.
The Victron was the only MPPT I tested with Bluetooth built in. All the other charge controllers in this review make you buy a 30-40 Bluetooth module for that feature. That helps justify the Victron’s price a bit.
The VictronConnect app has a lot of features. It can be a little overwhelming at first. But, once you learn your way around it, it can be quite powerful. You can use one of the many battery presets or, for advanced users, easily create and save custom charging profiles.
And that’s just the tip of the iceberg. Victron makes all sorts of accessories — sensors and shunts and the like — that can pair with the app as well and communicate with your controller to customize and optimize your system. It’s a solar nerd’s playground.
I also performed a power output test and the Victron placed first — by a hair. I wouldn’t put too much stock in these results because of the variables I couldn’t control (e.g. panel temperature, fluctuations in solar irradiance), but it was nice to see a first place finish from a top-of-the-line MPPT.
The Victron’s wire terminals are passable, but nothing to write home about. The screws felt high quality, but the terminals themselves were shallow and a little too close together for my taste.
Otherwise, the build quality of the Victron felt solid. The case and heat sink seem durable. It was also the smallest and lightest controller I tested, if that’s an important factor in your system.
I tested the bestselling Victron SmartSolar MPPT model on Amazon at the time of my research, which happened to be the 100/30 model (100V PV voltage limit, 30A charge current rating).
But Victron has a huge product lineup and sells SmartSolar controllers with a wide range of PV voltages (75-250V) and current ratings (10-100A). So if the model I’ve tested is too much or too little for your purposes, you can upgrade or downgrade accordingly.
Budget Pick: Renogy Rover 40A
| Rated charge current: | 40A | Max. PV open circuit voltage (Voc): | 100V |
| Battery voltage: | 12/24V | Battery types: | LiFePO4, sealed (AGM), gel, flooded, custom |
| Max. PV input power: | 520W @ 12V, 1040W @ 24V | Max. wire size: | 8 AWG (10 mm2) |
| Bluetooth monitoring: | Yes (requires additional purchase) | Temperature sensor: | Yes (included) |
Pros: Great value, easy to use, good mobile app (must buy Renogy BT-1 Bluetooth Module to use), custom charging profiles
Cons: Not compatible with Renogy Battery Voltage Sensor
Best for: Those looking for the best bang for their buck
Review
I’ve had the Renogy Rover 40A for over 6 months, and I’ve become quite familiar with it during that time.
It’s well-priced and easy to use. It’s compatible with all the most common types of solar batteries, plus has the option to create custom charging profiles.
Renogy has a mobile app called Renogy DC Home. To use it with the Rover 40A, you’ll have to buy the Renogy BT-1 Bluetooth Module.
The Renogy app is good, but I found it a little less feature-rich than Victron’s. For many users it will have everything you need. I suspect advanced users may want a little more customization, though.
The Rover’s wire terminals were good but not great. The terminals felt roomier than the listed max wire size, but the screws were a little loose and hard to tighten at times.
The screen on the Rover 40A displays nearly every system spec I could hope for. It’s also easy to use it to select your battery type, edit load settings, and create custom charging profiles.
In my power output test, the Rover tied for last with the EPEver Tracer 4210AN. They both output a max of 142 watts compared to the 146 watts of the Victron which placed first. I think the difference of 4 watts is negligible.
The Rover 40A doesn’t have a port for connecting a battery voltage sensor, which I don’t love. You have to upgrade to the Rover 60A or Rover 100A for that feature. Battery voltage sensors help charge controllers adjust their charging voltage to account for voltage drop, which is helpful in certain systems.
Overall, the Rover 40A is a good MPPT charge controller for the money. It has all the features and battery presets you need to set up your system quickly and easily. And for more advanced users, you can create custom charging profiles and buy the BT-1 Bluetooth Module for remote monitoring.
Honorable Mention: EPEver Tracer 4215BN
| Rated charge current: | 40A | Max. PV open circuit voltage (Voc): | 150V |
| Battery voltage: | 12/24V | Battery types: | Sealed (AGM), gel, flooded, custom |
| Max. PV input power: | 520W @ 12V, 1040W @ 24V | Max. wire size: | 4 AWG (25 mm2) |
| Bluetooth monitoring: | Yes (requires additional purchase) | Temperature sensor: | Yes (included) |
Pros: Excellent build quality, my favorite wire terminals, 150V PV voltage limit
Cons: Must make custom charging profile if using with lithium batteries, Bluetooth monitoring is harder to set up
Best for: Those looking for a charge controller with great build quality; users with lead acid batteries; users with lithium batteries who don’t mind creating custom charging profiles
Review
From a hardware perspective, the Tracer 4215BN — sometimes called the Tracer BN or Tracer BN Series — was my favorite charge controller.
It’s big and heavy and virtually one entire heat sink. The wire terminals were easily my favorite. They felt like tanks. And they’re the biggest in this review – capable of handling up to 4 AWG wire. If you like to overgauge your wires, this is one to consider.
However, the hardware in a charge controller isn’t the full story. Charge controllers also have a software component. When that’s lacking, it makes the controller harder to use.
I didn’t test the EPEver app, but from reviews I’ve read it’s a little clunky. The included MT50 screen is great, though. It’s easy to view all your system specs and select your battery type. If you’re using lead acid batteries, the Tracer BN is about as plug and play as any other MPPT.
But it has no preset for LiFePO4 batteries. You’ll have to create your own custom charging profile if using lithium. It isn’t that hard to do, but it’s certainly not as easy as selecting your battery type from a menu.
These usability hurdles are small, but more noticeable than on the other controllers in this review. If you’re comfortable with technical product manuals, they shouldn’t be difficult to overcome. And, once you do, you’ll have a great controller that feels like it could last a lifetime.
As a final heads up, the Tracer BN’s days might be numbered. While doing research for this article, I tried to find this controller on EPEver’s website, but couldn’t.
From years of product testing, I’ve come to see these removals as the first sign of a product’s discontinuation. For now it’s still available on Amazon, but time will tell.
Renogy Rover Elite 40A
| Rated charge current: | 40A | Max. PV open circuit voltage (Voc): | 100V |
| Battery voltage: | 12/24V | Battery types: | LiFePO4, sealed (AGM), gel, flooded |
| Max. PV input power: | 520W @ 12V, 1040W @ 24V | Max. wire size: | 6 AWG (16 mm2) |
| Bluetooth monitoring: | Yes (requires additional purchase) | Temperature sensor: | Yes (included) |
Pros: Cheapest MPPT tested, good mobile app (must buy Renogy BT-2 Bluetooth Module to use)
Cons: No custom charging profiles
Best for: Those who want a cheap MPPT and only plan to use preset battery charging profiles
Review
Based on its name, I wouldn’t fault you for assuming the Renogy Rover Elite is a more advanced version of the Renogy Rover. I know I certainly did.
But you’d be wrong. It’s actually a cheaper version. (Whose idea was that?)
The Rover Elite was close to being one of my recommended picks. It has a lot going for it: It’s the cheapest MPPT I tested. It’s compatible with all the main types of solar batteries. And, if you buy the Renogy BT-2 Bluetooth Module, you can connect the Rover Elite to the Renogy app to monitor your system from your phone.
Based on that, I think it’s a good budget option for DIY solar beginners, or users who just plan on using the battery presets.
But if you want to create custom charging profiles, know that the Rover Elite doesn’t have that option. I know from plenty of reader emails and Комментарии и мнения владельцев that advanced users like to customize their charging setpoints.
Unlike it’s more expensive cousin, the Rover Elite does have a battery voltage sensor port. You can buy a Renogy Battery Voltage Sensor and connect it to the Rover Elite to improve the controller’s battery voltage reading.
I’ve tested a handful of Renogy products over the years, and I always seem to come to the same conclusion: they’re good quality for the price. The Rover Elite is the same. Overall, it’s a good cheap MPPT.
EPEver Tracer 4210AN
| Rated charge current: | 40A | Max. PV open circuit voltage (Voc): | 100V |
| Battery voltage: | 12/24V | Battery types: | LiFePO4, sealed (AGM), gel, flooded, LiNiCoMnO2, custom |
| Max. PV input power: | 520W @ 12V, 1040W @ 24V | Max. wire size: | 6 AWG (16 mm2) |
| Bluetooth monitoring: | Yes (requires additional purchase) | Temperature sensor: | Yes (included) |
Pros: Fast power point tracking, custom charging profiles
Cons: Not the easiest to use, mediocre wire terminals
Review
The Tracer 4210AN — sometimes called the Tracer AN or Tracer AN Series — is a solid controller.
But, when pitted side by side against the others, it didn’t stand out to me in any way. I’m not sure what type of user I’d recommend it for.
I think it’s a good value for the money, but not as good as the Renogy Rover. The build quality is solid but not outstanding. I think the wire terminals are subpar.
On startup, it did track the maximum power point the fastest of any controller tested (in about 9 seconds on average, compared to the 57 seconds of its sibling, the Tracer 4215BN, which placed last). That’s something, I suppose.
It has a good screen and, on Amazon at least, the 40 amp model comes with the MT50 display included.
But I do want to underscore that this is a well-made unit. It works well, is solidly built, and even has the lowest power consumption of those tested. EPEver claims ≤12mA (it doesn’t say at what voltage), which is less than the 30mA (at 12V) of the Victron, the next closest.
If this controller is on sale, or you just prefer the EPEver brand, I’d say go for it. If it was the only MPPT I owned, I expect I’d end up being perfectly happy with it.
How to Choose the Best MPPT Charge Controller for Your Needs
Rated Charge Current
Also called: rated battery current, battery charge current or rated output current
The rated charge current is the maximum amount of current (in amps) that the charge controller can charge the battery at. It’s such an important number that it’s often included in the product name (e.g. Renogy Rover 40A — “40A” is the rated charge current).
30A-40A: Many popular MPPTs (including all the ones I tested) fall in this range. They can usually handle between 400-500 watts of solar at 12 volts and 800-1000 watts of solar at 24 volts. They’re best used with lithium batteries of 80Ah or greater and lead acid batteries of 130Ah or greater.
40A: MPPTs with charge current ratings greater than 40 amps are designed for large solar systems. They can usually handle greater than or equal to 600 watts of solar at 12 volts and 1200 watts at 24 volts. Some may also be compatible with 36V and 48V batteries and capable of handling even greater PV power inputs at these voltages.
Note: Charge controllers with load terminals may also list a rated discharge current (aka rated load current). This is how much current the controller can output through its load terminals.
Maximum PV Voltage
Also called: maximum PV open circuit voltage, maximum input voltage
Use our solar panel voltage calculator to calculate the maximum open circuit voltage of your solar array. Then, pick a charge controller with a maximum PV voltage greater than this number.
100V-150V: This is the most popular PV voltage range for MPPT charge controllers. Models in this range can usually handle 3-6 12V solar panels wired in series.
150V: MPPTs in this range are designed for large solar arrays. They can usually handle 7 or more 12V solar panels wired in series.
Note: Estimating the max voltage of your solar array is not as simple as multiplying open circuit voltage by the number of solar panels wired in series. This is because solar panel voltage increases as temperature drops. To get an accurate estimate, you’ll have to correct for temperature.
Battery Voltage
Also called: system voltage, nominal battery voltage
This number refers to the nominal battery voltage the controller is compatible with. You may see the word “auto” next to the battery voltage — e.g. “12/24V Auto.” This means the charge controller automatically detects whether you’re using a 12V or 24V battery bank.
12/24V: Many popular MPPT models are compatible with 12 and 24 volt batteries. Indeed, these are the compatible battery voltages of all the models I tested for this review.
12/24/48V: There are higher-end MPPTs compatible with 12, 24 and 48 volt batteries. These are usually MPPTs with higher charge current ratings.
12/24/36/48V: Some brands sell models that are also compatible with 36 volt batteries.
Note: Some charge controllers also list a max battery voltage in their spec sheet. As you’d expect, you don’t want your battery voltage to exceed this number.
Compatible Battery Types
Make sure the charge controller you’re getting is compatible with your type of battery.
Here are the most common types of solar batteries:
- LiFePO4 (Also referred to as lithium iron phosphate, LFP, or simply “lithium”)
- Gel
- AGM/Sealed lead acid
- Flooded lead acid
If a controller is compatible with a type of battery, it essentially means it has a preset charging profile for that battery chemistry that you can select when you set up the controller.
Custom charging profiles: Many MPPT controllers also offer the ability for you to create custom or “user” charging profiles. These let you select all the voltage setpoints — such as absorption voltage and float voltage — so you can tailor it for your specific battery.
In essence, custom profiles make the controller compatible with all main types of solar batteries. Many advanced users also like to adjust these numbers to try to maximize their battery lifespan.
Maximum PV Input Power
“PV” refers to solar panels, so this number is the max solar array wattage you can connect to the controller.
You’ll notice that the controller has different max PV input power ratings for different voltages. This is because watts is based on both volts and amps (W = V A).
If you’re having trouble figuring out what charge current rating you need, you can also refer to this number for guidance.
Bluetooth Monitoring
Being able to monitor and control your solar system from an app on your phone is great convenience. Don’t underestimate how nice it can be! MPPT controllers fall into three different buckets here:
Built-in: Some controllers have Bluetooth built in, meaning you don’t need to buy anything in order to start monitoring your system from your phone. Of the controllers I tested, only the Victron SmartSolar came with Bluetooth built in.
Additional purchase required: A lot of controllers require an additional purchase before you can use Bluetooth monitoring. You have to buy a Bluetooth module that connects to the controller. These typically cost 30-40. The remaining 4 controllers I tested fall into this bucket.
No Bluetooth: Some MPPT charge controllers come with no Bluetooth capabilities at all. The only way to monitor your system with these is through the screen or LED lights on the controller.
Wire Terminals
Look for good wire terminals with quality screws. Cheap charge controllers skimp on their wire terminals and you’ll notice right away. They’re easier to strip and you can’t tighten the screws down as much. They may be quicker to loosen over time.
Some people also like to over-gauge their wires. Thicker wires help minimize voltage drop and make it easy to expand your system later on. If that’s you, you’ll want to pay attention to max wire size.
Power Consumption
Charge controllers consume a modest amount of power, which will be listed on the specs sheet. In most DIY solar systems, the power consumption isn’t enough to make a material difference.
However, power consumption can come into consideration if your solar panels will go for long stretches without receiving sunlight. For instance, one reader from Scandinavia wrote to me about how charge controller power consumption factored into his buying decision because the solar panels on his off-grid cabin were covered in snow for most of the winter. He didn’t want the charge controller to consume so much power that it fully drained his batteries.
In these situations, look for a controller with low power consumption. Most charge controllers have lower power consumption at lower system voltages, so you may want to keep your battery bank at 12 volts. PWM charge controllers tend to consume less power than MPPTs, so you may want to also consider a PWM model.
Temperature Compensation
If you’re using lead acid batteries and they’ll be experiencing wide temperature swings, you should look for a charge controller that adjusts its voltage setpoints based on temperature — a featured called temperature compensation. Lithium batteries don’t need temperature compensation.
To have this feature, the controller needs to have a temperature sensor. The sensor will either be a built-in internal sensor, or an external sensor included in the box or available as an additional purchase.
If it’s an external sensor, You plug it into the temperature sensor port on the controller and then tape the probe to the battery.
Operating Temperature Range
Pay attention to operating temperature range if your charge controller will be experiencing wide temperature swings — such as if it’s located in a boat, RV, or campervan without AC. The higher-end models are typically able to handle wider temperature ranges.
MPPT vs PWM Charge Controllers
MPPT charge controllers are more expensive, but more efficient. Most are around 95% efficient.
PWM charge controllers are cheaper, but less efficient. They are around 75-80% efficient.
What’s more, MPPT controllers often have higher charge current ratings, such as 30 amps or more. This means you can connect more solar panels to them. (The MPPT models included in this test, for instance, can handle solar arrays of 400-1000 watts depending on system voltage.) They also have higher PV voltage limits, so you can connect more panels in series which can save you money on wiring.
PWM charge controllers usually have lower charge current ratings, such as 10-30 amps, making them best suited for solar arrays of 400 watts or less. They often only have high enough PV voltage limits for 1-2 12V solar panels in series. If you’re using lots of solar panels with a PWM, you’ll probably have to wire them in parallel which can increase wiring costs.
The Bottom Line
I liked all of the MPPT charge controllers I tested for this review. I’d be happy to have any of them in my system. Alas, the job of a reviewer is to rank the options from best for worst.
After testing 5 MPPTs side by side and comparing their spec sheets, I think the Victron SmartSolar MPPT is the best MPPT charge controller on the market. I thought it had the best build quality and was the easiest to set up and use.
The Renogy Rover 40A has the best bang for your buck. It’s a well-made model that can be paired with Renogy’s mobile app if you also buy the BT-1 Bluetooth Module.
Lastly, the EPEver Tracer 4215BN is built like a tank and has the best wire terminals of any charge controller I’ve ever used. It’s not compatible with lithium batteries out of the box, but you can use the included MT50 screen to create a custom charging profile.
As a reminder, all the charge controllers I tested offer models with different charge current and PV voltage limits. If you like the Victron, for instance, but need a higher current rating, consider the Victron SmartSolar MPPT 100/50. It has a 50 amp current rating, compared to the 30 amp rating of the model I tested.

Due to the relationship between the load output and solar input (daylight/darkness etc) the load output does not supply consistent power suitable for operating appliances such as a fridge/freezer. We therefore do not recommend connecting electronics such as a fridge/freezer that require reliable consistent power directly to the MPPT Solar Controller. Instead, all accessories should be directly connected to your battery bank via appropriately fused circuits.

Please Note: This MPPT Controller is not waterproof.
This unit is not a full battery management system, rather a charge controller that can supply power to small accessories such as LED lights. Due to the relationship between the load output and solar input (daylight/darkness etc) the load output does not supply consistent power suitable for operating appliances such as a fridge/freezer. We therefore do not recommend connecting electronics such as a fridge/freezer that require reliable consistent power directly to the MPPT Solar Controller. Instead, all accessories should be directly connected to your battery bank via appropriately fused circuits.

What Size Charge Controller for 400W Solar Panel?
So you want to know what size charge controller to buy for your new 400W solar panel system. But what exactly is a 400W solar panel? And how much power does a 400W panel produce? In this article, we’ll discuss the important details on sizing the right controller, the size of 400W solar panels, how much energy can the 400W solar panel produce and more.
How do you choose the right charge controller for a 400w solar panel? To find the right size for your system, consider several factors, including the battery system voltage you have, how much output you’re looking for and how much energy your system needs. Read on to learn more!
Before we go any deeper, let’s conclude: for a 24v 400w solar power system you need a 24v 20A MPPT charge controller, for a 12v solar power system you need a 40A Solar charge controller, calculate the charge controller size by using this size tool or simply by the formula (watts/battery volts = amps 25%).
How to size a solar charge controller
When determining how to size a solar charge controller for 400 W solar panel, you must first take into account the power and voltage your panel can produce. and the total voltage of the battery systems, In general, To properly size a solar charge controller for 400W, you must first choose a voltage range for the panels and the battery. you should size your controller 20% higher than your panel’s power output. However, you must consider environmental conditions and wattage consumption when sizing your solar panel. To determine the correct solar charge controller for your system, you can use a sizing calculator.
We prefer MPPT controllers, as The MPPT solar controller will optimize the power output of your panels by monitoring the voltage and current in the circuit. helps you get the most power from the panels.
What is a 400w solar panel
When choosing a charge controller, it’s important to understand how the wattage of the solar panel is rated, Solar panels are sized based on their output capacity. For example, a 400W solar panel can be rated for 400 watts of output under ideal Standard Test Conditions (STC), as it will be affected by your specific location. the actual output will depend on many factors, including the tilt and shade of the panels, as well as weather conditions.
How Many Amps Does A 400 Watt Solar Panel Produce?
There is no label on a 400-watt solar panel, but you can find out its maximum output by multiplying its open circuit voltage (Isc) by a number of factors. The maximum current is calculated by multiplying the Isc by ninety percent, and the maximum working current by two thirds. If you’re using the solar panel for a whole house, you may want to use the smaller 400-watt panel. But if you want to power a small home, it might be more economical to introduce a larger board.
Using a 400-watt solar panel is sufficient to power most home appliances, including small electrical appliances like a cell phone charger. It can also run a few large appliances at once, like a refrigerator, air conditioner, or a PC. The best way to test a solar panel’s power is to plug it into a battery for backup. In addition to avoiding surges, you should avoid plugging large devices directly into the solar panel. For this, you can use a larger battery or multiple 400-watt solar panels in parallel.
The maximum output of a 400-watt solar panel is approximately 24 to 26 amps per hour during summer. However, this may vary in other seasons. Summer is when solar power production is highest, while winter and colder seasons will produce lower output. In these seasons, you can use the power generated by your solar panel to recharge your batteries or access the main grid for your home. If you are unable to use all the power your 400-watt panel produces, you can always store it in a battery bank.
What Size charge controller for 400w solar panel
To determine what size charge controller to buy for your solar panel, look at the current and power of your panels. Then, multiply the current by twenty percent to find out the maximum operating voltage and current. Remember, your solar panels may be placed in parallel or series, so you will need to factor in the size of each controller accordingly. You may also need an extra charge controller if your system is too large. In order to determine the right size charge controller for your 400w panel, you should look up the voltage of the panels that you will connect to the charge controller.
A 400 watt solar panel requires a charge controller with a current flow of at least 120% of its solar power. It is best to go for a MPPT charge controller rather than a PWM controller, because they work better with solar panels.
You can calculate the solar controller size by this:
400W/24V=16A and plus additional 25% and thus you need a 20 Amp Charge controller at least.
400W/14V=33A and plus additional 25% and thus you need a 40 Amp Charge controller
