Solarway is a professional off-grid power inverter supplier, is a sino-german joint venture, mainly engaged in off-grid power inverter/MPPT and PWM controller, research and development, manufacturing and sales, we can provide customers with off-grid power INVERTER OEM and ODM. The factory is located in Jiaxing, Zhejiang Province, China. We have R & D Center and After-sales Service Center in Beijing, China and Leipzig, Germany.
MPPT solar controller (also known as an intelligent solar charge controller, solar charge controller, PV controller) can intelligently regulate the working voltage of solar panels, letting the solar panels always work at Maximum Power Point of V-A curve. Compared with ordinary solar controller, this MPPT controller can increase the efficiency of PV modules by 10%-30%.
