EPSolar eTracer MPPTEPSolar eTacer MPPT

EPSolar eTracer MPPT is an advanced Maximum Power Point Tracking (MPPT) controller for off-grid photovoltaic (PV) systems up to 3KW. The controller features a smart tracking algorithm that maximizes the energy harvest from the PV by rapidly finding the solar array peak power point in all weather conditions. The controller provides higher efficiency up to 98% with lower power loss.
Include up to 450 days data logging by connecting to Ethernet.[/vc_column_text][vc_row_inner][vc_column_inner width=”1/2″][vc_column_text]
