Review on 🌞 EEEKit 30A Solar Charge Controller: Advanced LCD Display, Dual USB Ports, Timer Setting and PWM Auto Parameter by Eric Schwalbe

Like most guides with these foreign devices they suck but the device is pretty intuitive and easy to hook up. I found that all of the answers to the above questions were wrong. Just remember to connect the battery to the controller first so it can detect the voltage. I am using 2 36 volt solar panels connected in parallel which will produce 18 amps in bright sunlight. I also use two 12 volt batteries connected in series to get 24 volts. I connected the batteries first and the little battery icon appeared on the display and the controller read 25.6 volts. Then I connected my solar panel and the little solar panel icon lit up. The system worked perfectly.
