BNT 500W - 5kW
Solar Inverter / Controller
BNT series solar inverter/controller is a classic pure 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. BNT adopts low frequency transformer based design with strong loading capability. The inbuilt AVR function enables a wide input voltage range. It outputs pure sine wave power, is capable of supporting all kinds of loads with full protections against overload, short circuit, low battery voltage, surge, and lighting, etc.
