SR series MPPT solar charge controller adopts the industry-leading peak power point tracking technology to achieve the peak energy tracking of solar panels, so that it can quickly and accurately track the peak power point of solar cells in any environment and obtain the peak energy of solar panels in real time, which significantly improves the energy utilization rate of solar systems and is an upgraded alternative to traditional solar charge and discharge controllers. The product can effectively store the DC power emitted by solar cells in the battery, which can effectively solve the living and industrial electricity consumption in remote areas that cannot be covered by the conventional power grid.
