Upgraded ESmart3 MPPT 40A 60A Solar Controller 48V/36V/24V/12V Auto Back-light LCD Max 150VDC Input Energy Saving RS485 Port

40a mppt solar charge controller 48v



ESmart3 series is the third generation of eSmart mppt controller, combined with the second generation of high conversion efficiency, back-light LCD display, control mode, connect way, internal structure etc. features, also optimized the following points:

1.Increase all kinds of protection function to be used more reassuring.

2.Add the LOAD sampling to be used more clear of output load.

3.Wider PV Input voltage than eSmart2, so it suitable for more kinds of PV modules

4. Reduce the static standby self-consumption, energy saving and more simply for small system.

Choose ESmart3, more intelligent in life!
