BNG 0.3kW - 1.5kW
High Frequency Integrated Off-Grid Solar Controller Inverter
BNG series solar inverter/controller is a classic modified sine wave solar generator which is consists of solar controller and solar inverter.
Solar controller is an important part of solar power system. It could intelligently control and protect system charge, discharge and loading status. Its quality and performance directly affects the reliability of the solar power system, especially the lifespan of the battery. Overcharge and over discharge could cause damage to the battery or even cause fire.
Solar off-grid inverter converts DC power from solar panels into AC. BNG adopts high frequency topology with unique SMT and modularized artwork design. Utilization of maximum power from solar panels by BNG reduces end-user cost and pay-back period of the investment.
