    Frequently Asked Questions
    Does this solar pumping system require batteries?
    No, the system is designed to use water storage instead of battery storage. It directly drives the pump, which increases reliability and significantly reduces construction and maintenance costs.
    What is the advantage of the VI MPPT algorithm?
    The VI MPPT algorithm provides fast response speeds and high stability. It effectively solves common problems like poor tracking and water hammer damage that occur during rapid changes in sunlight intensity.
    Can the system operate automatically?
    Yes, the system features full digital control and automatic operation. It can be set for timing power on/off and runs without human intervention, making it ideal for unattended sites.
    What kind of protections are included in the inverter?
    The system includes comprehensive protection for PV input under/over voltage, reverse polarity, DC over-current, output overload, short circuits, dry well conditions, overflow, and pump blocking.
    Can I monitor the system performance remotely?
    Yes, the system is equipped with RS485 data communication, which allows for remote monitoring as an optional feature.
    What is the protection rating of these inverters?
    Models up to 30KW generally feature an IP65 protection degree, while larger models (37KW to 150KW) are rated at IP20.
