SCC80AMPPT 80 Amp MPPT Solar Charge Controller; Charges 12, 24, 36 and 48 Volt Solar Systems; 4 Stage Charging; Battery Type Selector; Stackable; Over Temp Protection

This charge controller is very heavy duty. It also weighs a lot, you'll need a hefty place for it. It works great. The only thing is there isn't a options for farenheit on the battery temp. Other than that it works great with my lithium batteries

Great charger for solar. It's quite on account it doesn't use a fan.

I purchased two identical solar charge controllers, but only one functions as expected. The other was faulty right from the start, requiring immediate return for repairs, and subsequently broke again. Despite claims from AIMs that the issues stem from my system, this is not the case. Further research reveals numerous similar complaints about this company online. Additionally, the advertised remote management software does not work. When attempting to use the warranty, I found that not only does the buyer pay for shipping of these heavy units, but AIMs also frequently claims that issues are not covered under the warranty. I have since switched to a different brand and recommend that potential buyers consider doing the same.

This was a lot more than I wanted to spend but I was very leery of buying something cheap from a foreign country. So I took a chance and I'm glad I did. It works perfectly fine. I haven't had any problem with it. It seems to work exactly how it's supposed to. The only reason for docking a star is because there was no explanation in the manual of the abbreviations used on the digital display. I had to call customer support and their rather lackadaisical response made me wonder for a moment if they really knew what they were talking about. For reference, my system includes 4 230-watt solar panels, a 200ah LiFePo4 Plus battery and a 3,000-watt pure sine wave inverter.

Works great i am running 70 amps thru it

I have the 80 amp unit, and I love it. My 40 amp unit will serve as a spare, and I'll also use it in my van too !

Excellent

I purchased this unit because I was told they could be run together being fed from different arrays. 1st one unit failed and was fixed, now the 2nd unit has failed, but caused my inverter to shutdown because of high battery voltage. Amazon won't cover the warranty repair and AIMS won't take the unit back under warranty repair so I'm out the money. I wouldn't buy this Unit from Amazon get it from the inverter store directly so you have a warranty. 30 days for the price of the unit is seriously a joke for a warranty.
