Review on 🌞 AIMS Power SCC40AMPPT 40 Amp MPPT Solar Charge Controller for 12, 24, 36, and 48 Volt Solar Systems; Advanced 4 Stage Charging; Battery Type Selector; Stackable Design; Enhanced Over Temperature Protection by Caleb Quade

This unit was installed to replace a MorningStar 60 MPPT. Not because the MS's were bad, but simply because I wanted to use them elsewhere and change the config. This AIMS device was and still is defective. It only charges to 54 volts and then goes down to zero. It looks like the firmware is corrupt or the voltage sensor is not calibrated. I sent photos of AIMS and all specifications several times. Back and forth they kept asking for the same information and then they told me my solar panels were connected wrong and said I connected them all in parallel. This is not the case and I have never claimed anything of the sort, if that were the case the MS devices would never function perfectly for many years. After that they won't answer me. This was a company I bought 10,000 products from and they had good success and I recommended them and then when the first product had a legitimate problem they treated me like that. They treated me with no disrespect or confusion. I took out the block and replaced the MS blocks. A few months later I still have this AIM which was bad on arrival and had no recourse. Because I didn't install it fast enough to fix the problem, Revain didn't return it after 30 days.
