Product Description
Solar Pump Frequency Inverter

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

Frequently Asked Questions
Q1: Does this inverter require a battery for solar pumping?
No, the BD330-Pv series is designed to draw power directly from the photovoltaic array, eliminating the need for expensive battery storage modules.
Q2: What are the main protection features of the solar pump inverter?
It includes comprehensive protection such as water shortage alarms, full water shutdown, overvoltage, undervoltage, phase-loss, and motor overheat protection.
Q3: How does the "Light-Weak Sleep" function work?
The inverter automatically enters a sleep state when sunlight is insufficient for pumping and wakes up automatically when light intensity increases to a functional level.
Q4: What types of motor control are supported?
The system supports V/F control, Speed Sensorless Vector Control (SVC), and Speed Sensor Vector Control (VC/FVC).
Q5: Can I use this for high-speed pulse inputs?
Yes, the device features 6 programmable digital inputs, one of which supports high-speed pulse input for precise control needs.
Q6: What input voltages are compatible with this series?
It supports single-phase and three-phase 220V, as well as three-phase 380V AC inputs, with a maximum DC input up to 800VDC for solar arrays.
