BC900GF Series PV Inverters

BC900GF is a special variable frequency drive device for photovoltaic water pumps. It is equipped with a high-precision and fast MPPT tracking algorithm. The light energy utilization rate can reach 99%. The water pump can be started smoothly in low-light environments and is suitable for various photovoltaic array direct drive conditions. The product adopts optimized vector V/F control, low-frequency and high-torque output, soft start and stop to greatly reduce motor impact, and is suitable for three-phase asynchronous and permanent magnet synchronous water pump motors. It supports dual inputs of photovoltaic DC and mains AC, and automatically switches power supply during dark periods to achieve 24-hour uninterrupted water supply. It has built-in multiple protections for dry pumping, shutdown when full of water, overvoltage and underflow, and stalling. It automatically sleeps and wakes up when the light is insufficient, making it suitable for unattended scenarios. It comes standard with Modbus communication
