Review on ⚡️ AMPINVT MPPT Solar Charge Controller 12V 24V 36V 48V Battery System Auto, Max Input 150V PV Solar Regulator Negative Grounded (MPPT-60A): Efficient Solar Charging Controller for Multiple Voltage Levels by Keith Baker

This is a very good controller, I have used many expensive ones like the Outback and this one is much better. The metal case is very heavy and well made. The circuit boards inside are very professional, nice and clean. I run 2 of them and they both work great together. All in all very easy to set up. I am charging 7s 10p 18650 lithium batteries for our off grid solar system, with lithium you just need to set the float charge level and in my case it is 29.2 volts and the controllers are in place. The only problem I have is that I wish the spade lugs were bigger, I think they will take 6 gauge. My wife and I have been in the self power business for many years so any of you looking for a good product will not be disappointed. The fan turns on at around 20 amps and if you buy one your manual will likely say that the passcode is three down arrows and then three up arrows. If that doesn't work, change the code. Five stars! I bought an 80 amp one a few months ago and it works great. One big difference is that the lugs are nice and big, three times the size of the 60 amp lugs.
