Magnum PT-100 100A 200VDC MPPT Charge Controller
The PT-100 is an MPPT charge controller that harvests the full amount of usable energy from the PV array and delivers it to the batteries. The MPPT algorithm in the PT-100 finds the array’s maximum power point and works there while controlling the output current to 100 amps and the battery voltage to completely charge the battery. Auxiliary relay with programmability built-in for system access. Energy harvest data and battery Ahr/Whr data are stored for up to 255 days using internal data logging capabilities. To view this detail, use the optional remote.

For logistical reasons, all shipments are made using our company’s shipping account.
Estimated Delivery Time For standard delivery, most orders will arrive at their destination within 7 to 10 business days. Please note that these estimates are subject to change depending on carrier’s operational capabilities and other factors beyond our control.
Inspecting Shipments Upon Delivery When your order arrives, it’s of utmost importance that you meticulously inspect your shipment upon delivery. If delivered by a freight truck, you should reach out to the freight carrier using the phone number given on the carrier’s bill. By signing the delivery receipt without noting any potential damages, issues, or if you’re unable to inspect the delivery, you are legally confirming that you’ve received the shipment in good condition. Please be advised that USSolarSupplier can’t be held responsible for any damages or missing items not listed on the delivery receipt. If you decide to accept a package that’s visibly damaged, make sure to note on the delivery receipt that you’re signing for a damaged package. However, please note that USSolarSupplier can’t be held responsible for any damages or missing items accepted via signature delivery. After receiving your shipment, it is crucial that you carefully count and inspect the contents before acknowledging delivery. In the unlikely event that your shipment has been damaged during transit, please take photos of the materials and note the damage on the Bill of Lading (BOL). If there is major visible damage, you should reject the delivery outright. In case of damages, it is required that you notify US Solar Supplier by email (kyle@ussolarsupplier.com) within 24 hours of delivery. Please include the signed BOL, as well as any additional photos or supporting documents. If the BOL is not properly noted at the time of delivery, US Solar Supplier cannot be held responsible for additional costs for replacement materials. All returned items are subject to inspection and approval.
Expedited Shipments We strive to ship expedited orders on the same day we receive them. However, orders placed after 1:00 PM Eastern Time (10:00 AM Pacific Standard Time) may not ship the same day. Expedited orders placed over the weekend or on major holidays will be processed and shipped on the following business day. Please note that carriers do not deliver on weekends or major holidays, with the exception of Saturday delivery. If you require Saturday delivery, please contact our sales department at 1 (800) 230-7004 for assistance.
Out of Stock and Backordered Items Occasionally, an item may have a lead time or be backordered after your order is received. If there is a lead time associated with your order, we will contact you to confirm whether this lead time aligns with your project deadline.
Please include this information in the order notes when placing your order, and we will do our best to accommodate your needs. For other special requirements, please call our sales department at 1 (800) 230-7004 before placing your order.
Multiple Shipments
We warehouse our products across the United States, and occasionally, we may need to ship your order from two or more different locations. In such cases, we will never charge you more for shipping than your original payment. If you require your order to arrive in a single shipment, please contact our sales department when placing your order at 1 (800) 230-7004 or add this information to the Order Комментарии и мнения владельцев box. To consolidate certain orders, we may need to bring the products into our Vista office and combine them before shipping, which may result in an additional 3-5 day lead time and additional shipping charges.

Introduction: Make the Harbor Freight 45W Solar Panel Charge Controller Useful With a Simple Mod.
Like many of us who are interested in solar power, I bought a Harbor Freight 45 Watt Solar Panel kit for about 150 which came with three solar panels, and a charge controller. It was exciting times when I set it up several months ago to see the front panel lit up. I thought that I was getting enough solar juice to charge my SLA batteries. However, the excitement was short lived. I was foolish enough thinking that the light was all powered by solar for the very first night, and forgot the fact that the battery was fully charged already before I connected it to the solar panel. Just like many found out, the charge controller doesn’t appear to be working as we expected. For example, my SLA battery originally had 12.5 Volt. During the day, the front panel shows about 13-14 volts so I leave the charge controller on, but when I come back from work, I found that the battery wasn’t charged at all. In fact, the voltage would go down about 0.1 volt to become 12.4 volt. What’s going on?
As usual I searched for answers on the internet but most people simply complain that this particular charge controller is not efficient, or it can only be used as a power distribution device. To get a better charger, one would need to invest another 100. Basically, the solar panel kit is only good for demonstrating the concept (I have to say that from outside, the charge controller looks nice and solid).
Recently, I got some spare time and started making diagnosis on this charge controller and I found that while it indeed charges during the day, it discharges as the sun goes down. I suspect that when the voltage from the solar panel is below the voltage of the battery, it may be discharging the battery. I don’t know this for sure since I haven’t open the device to see the design. This device does discharge at night at about 30mA if you leave it on (the LED display uses power unless you turn the LED display off which is recommended).
Step 1: Add a Blocking Diode to Stop Discharging the Battery
One experiment I did was to simply add a blocking diode on the back of the charge controller. I initially placed the diode on the battery side but based on recommendations from evilmunkey, the diode should now be put on the solar panel side. The diode I am using is 1N5822 which happens to be in my toolbox so I guess many other diodes would work as well. 1N5822 can handle 40v 3A so I use two of them in parallel to make sure it can handle the current from the solar panel. Also make sure that the cathode lead of the 1N5822 should be connected to the charge controller side while the anode should go to the solar panel side. Previously I experimented with putting the diode on the battery side but I was concerned that it might overcharge the battery so now the diode is on the solar panel side. After the modification, my SLA battery is charged better.
Step 2: Caveats With the Blocking Diode
Since I don’t know the charging circuit inside the box, the effect of this added blocking diode on the solar panel and battery charging is not clear. Theoretically the charge controller should already have blocking diodes on the solar panel side, otherwise it will give all back the solar power at night. The ultimate solution would be to look at the components inside the box and see what it’s doing. There are many different kinds of controllers and they all work differently. I assume that this is a PWM type but I don’t really know. For example, does it have a microcontroller to control the voltage? What about current limiting? Given all the unknowns, I wouldn’t risk charging any expensive batteries. In my case, I salvaged some old 12V SLA batteries by refiling with Epsom water. I also leave the battery outdoor in case of outgassing. So far it works fine and the battery is actually revived to a certain extent. This is very much an experiment so be careful not to overcharge. Finally, make sure to add an inline fuse near the battery terminal (such as 5A). It’s better to be on the safe side. If anyone has any better suggestions improving this unit, please let me know. I may open the box in the future and write another instructable later. For now, I need to move on to the next project with desulfator.
