ESmart3 MPPT 40A Solar Laadregelaar Max 150VDC Input Back-Light LCD Solar Regulator RS485 Poort met LCD12V 24 V 36 V 48 V Auto

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. functions, also optimized the following points:

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

2. Add the TAX sampling to be used more clearly of output load.

3. wider PV input voltage than eSmart2, so it’s suitable for more types of PV modules

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

Choose ESmart3, more intelligent in life!
