Using technology from the EG4 3kW All-in-One Solar Inverter, the EG4 MPPT100-48HV is a simple, affordable, yet reliable solar charge controller MPPT(Maximum Power Point Tracking).

The EG4 MPPT100-48HV solar charge controller extracts the maximum available power from your PV modules and safely converts it to a lower voltage to charge your battery bank. Optimize your new or existing solar power system by adding this unit and take advantage of additional solar harvesting capabilities.

BMS Communication

The MPPT charger is able to communicate with EG4 batteries when operating with non-EG4 compatible inverters via its RS485 BMS port.

What is an MPPT Charge Controller?

An MPPT, or maximum power point tracker is a DC-to-DC converter that optimizes the power between the solar panel array, and the battery bank. Basically, they convert a higher voltage DC output from solar panels down to the lower and consistent voltage needed to charge batteries.
