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.
Features:
1. The real short-circuit protection.
2. The universal socket design, it is suitable for any plug.
3. Multi-protective functions with low voltage, overload, over current, high temperature and high pressure, short circuit.
4. Advanced circuit design with ultra low power consumption
5. Unique SMT + module combination processing technology to ensure premium stable performance.
6. High efficiency.
7. Auto controlled fan cooling
8. Intelligent large LCD displays the status of loading, overloading, battery cap, ultility power, frequency, faulty etc.
Range of application: Mobile phone charging, laptops power suply, TV sets, Air conditioner, Refrigerator, Professional tools, instruments, small home solar power system.
Suggest to connect with 4 x 12V/200Ah batteries.
