Review on 🌞 Efficient EPEVER 40A MPPT Solar Charge Controller for 100V PV Max Input: LiFePo4 Battery Charger with MT50 Remote Meter & Temperature Sensor Tracer4210AN by Jeff Johnson

You should know that 40a is what a controller is, I also think it's max 720 watts, read the instructions with it, I have 600 watts on 3 x 200 panels, I draw 2 kilowatts a day, winter spring, fl. I have 6-6 volts 215 amps. Sam's Club Hour Batteries. At 10 o'clock I am fully charged with 14.5 volts. This controller is so reliable after 3 months of use that I exceeded the advertised 520w or so because the manual says it can exceed those limits and if the amps are bigger it will just lose power. Really I need more batteries, just read the user manual, you can download this controller and it will handle it.
