Inverters
Most homes are wired for AC electricity, but most solar panels and small wind turbines produce DC electricity. Solar inverters convert direct current (DC) electricity into alternating current (AC) electricity. Because of this, unless your solar system runs DC only, an inverter is usually a central component in both off-grid and grid-tie solar systems. Each type of system requires a different type of inverter:
- Off-grid inverters where a charge controller sends DC power to a battery bank, then an inverter converts the DC to AC for the home.
- Grid-tie inverters with no battery bank, DC power goes straight to the inverter, and then to the home as AC. Excess AC power is sent backwards through a special two-way net meter, and out to the power grid for others to use. Your meter runs forward or backwards depending on if you are buying or selling power at the time.
- Hybrid inverters connects to both a battery bank and the utility grid, letting you draw or send power from both.
- Battery based inverters are best for small projects or when the grid is not available at your location.
- Grid tie string inverters are best when you don’t have a lot of shading.
- Micro inverters are best when you have shade on some of the roof or multiple roof orientations.
- Hybrid inverters are best you want solar and batteries and be connected to the grid.
- Mobile inverters are best when you’re on the go, in the RV or on the boat.

Sizing an Off-Grid Solar Inverter
Choosing the right off grid inverter for your off-grid solar system depends on accurately calculating your electrical loads and usage patterns. The size of the inverter you need is based on your ‘peak load’ requirements. all the AC loads that could be turned on simultaneously.
For example, if you will be using the 1500 watt microwave, while also running 100 watts of lighting and running a refrigerator that will draw 500 watts of power, you will need an inverter that can handle at least 2100 watts (1500 100 500). Once you have identified a minimum wattage, you will select a style that has the same nominal voltage as your battery bank (12, 24, or 48 VDC).

Major Types for Your Solar Power Inverter
Now, let’s move to the best solar inverter types.
When you wonder about the most common solar inverter, it is a description of a String one. Behind the name hides the functionality. The inverters are linked to a certain string of solar panels in series. It converts the Direct Current energy into housing usable Alternating Current. The connection may take place in different ways. For example, a solar array can consist of at least 15 solar panels with 250Wp each. Then, each panel is connected to strings. You can find such a type in Europe and Asia the most.
The next type is hybrid or battery one. It is a combination of the best solar power inverter with a battery as one unit. It is a good option if you have regular power issues. In the case of a blackout, it will provide basic power support until the issue is over. The popularity behind this type is its relative cheapness compared to string inverters.
This type is also called a stand-alone system. It requires potent battery inverters with separate chargers. They can form a setup with either AC or DC solar systems. Today, experts also convert such models into multi-mode devices. Then, it is popular because of its relative eco-friendliness and sustainability. You minimize the carbon footprint.
Last but not least, micros inverters. They are compact because they are attached to individual systems directly. They will fit complex roof designs and locations linked to extreme shading. Even the compact size does not prevent you from their high costs. You will spend more than with other inverters if you choose a good model.
Solar Panel Inverter Choosing Criteria
If you decide to buy one, you should understand the factors to pay attention to when selecting. As of now, consider the following criteria:
- Quality, Trustworthiness of the Brand. Logically to assume, you should stick to popular brands of inverters for solar panels. They, in turn, will mean high-quality, longer and better lifespan, and a great warranty. The latter is extremely important if you live in areas with fluctuating weather conditions;
- Customer Service. When you buy PV solar inverters, you should receive a proper consultation or even guidance from experts. In case of any inquiries, the seller or manufacturer itself should address them;
- Warranty. Ensure your inverter has a good warranty to rely on. At least 10 years should be there. Otherwise, you will simply come across huge expenses on repairs and maintenance;
- Extra perks. Modern inverters come with extra features. For instance, there should be convenient panel-level optimization;
- Solar inverters price. Agree that a price greatly dictates your choice. So, ensure it is neither exorbitant nor cheap. Find a golden mean.
Best Commercial Solar Inverters in 2023
If you seek commercial solar inverters, you can find the below examples a good fit.
Check the Durability of the Inverters
Purchasing a solar inverter should be a long-term investment. It is, therefore, crucial to consider performance and lifespan under adverse weather conditions.
Australian weather can be particularly harsh in the summer months so an ability to handle high temperatures is usually a top priority. Yet, you should also be aware of any potential issues arising from interactions with the cold or rain.
Usually, high temperatures raise the solar power system’s voltage, and low temperatures decrease its voltage. Once the voltage exceeds the maximum specification, it can cause irreversible damage to the solar inverter. On the other hand, the extremely cold weather is also likely to make the solar inverter stop working.
When choosing a solar inverter, go for one which is resilient to rough climatic and atmospheric conditions. You can consider looking for a solar inverter that uses the IP65 tech as it ensures it is seldom affected by terrible weather conditions.
What is Your Budget?
If you are eager to go completely off the grid, then off-grid inverters are the best choice; however, they can be costly. Alternatively, you can opt for a grid-connected inverter which is less expensive and can help you significantly subsidize your utility bills via net metering.
The more capable an inverter is to handle larger loads, the more expensive it will be too. So you should try to get an understanding of your energy needs first.
Do you Have an Estimate of Your Energy Requirements?
Do you know the amount of energy you will need, whether it’s for your home or business? Estimating your energy requirements is essential before buying a solar inverter.
In addition, your solar power requirements will directly affect the size of the solar panels and, by extension, their pricing.
Consider buying a solar inverter of a slightly higher capacity than your energy needs, as there might be some energy losses in the system or particular periods where you might need a little more.
