50 Amp MPPT Solar Charge Controller

This MPPT solar controller is an advanced maximum power point tracking (MPPT) battery charger for off-grid photovoltaic (PV) systems up to 1.2kW. The controller provides the industry’s highest peak efficiency of 97% and significantly less power loss compared to other MPPT controllers.

The MPPT controller features a smart tracking algorithm that maximizes the energy harvest from the PV by rapidly finding the solar array peak power point with extremely fast sweeping of the entire I-V curve. It can increase your photovoltaic array power yield up to 30% compared to non-MPPT controllers.
