Product Description
Solar Water Pumping Inverter
The BD330-Pv series products do not require battery modules, and the power supply is directly sourced from the photovoltaic array to realize PID control and MPPT functions. Based on the original protection functions, the product adds functions such as light-weak sleep, light-intensity wake-up, water shortage alarm, and full water shutdown to ensure the normal operation of the water pump.

Frequently Asked Questions
Does this solar inverter require batteries?
No, the BD330-Pv series is designed to work directly with photovoltaic arrays, sourcing power from solar panels to drive the pump without needing battery storage.
What is MPPT and why is it important?
MPPT (Maximum Power Point Tracking) ensures the inverter extracts the maximum possible power from the solar panels under varying sunlight conditions, optimizing water pump efficiency.
How does the auto sleep and wake-up function work?
The inverter automatically enters sleep mode when sunlight is too weak to drive the pump and wakes up when light intensity becomes sufficient, ensuring autonomous operation.
Can it protect the pump from dry running?
Yes, it includes a water shortage alarm and underload pre-warning functions to protect the pump from damage when water levels are too low.
What motor types are compatible with this inverter?
It supports a variety of motor control modes, including V/F control and vector control for asynchronous motors, and is compatible with different PG cards for closed-loop control.
Is it possible to use AC grid power as a backup?
The system supports AC input (220V/380V), allowing for flexible power sourcing from either the solar array or the utility grid when necessary.
