The BD603 series solar pump inverter from Zhejiang Folinn Electric Co. Ltd. is a vector control inverter designed for solar powered water pumps, eliminating the need for batteries by drawing power directly from PV panels. It supports two control modes, CVT and MPPT, with maximum power point tracking ensuring optimal energy harvest under varying light conditions. The unit integrates PID control for precise water level management, including automatic stop at high water, restart at low water, and underload protection with pre-warning signals.
Built with full protection and diagnostic mechanisms, the inverter handles faults such as water level sensor failures and weak light conditions by entering auto-sleep mode, then waking automatically when light intensity increases. It is compatible with three-phase asynchronous pumps and motors, and supports both DC and AC input, allowing grid power to operate the pump during low sunlight or rainy days via parameter settings. The design prioritises ease of installation and minimal maintenance, with RS485 enabled for real-time remote control and monitoring.
This inverter is typically deployed in agricultural irrigation, municipal water supply, and off-grid solar pumping systems where reliable, energy-efficient operation is critical. Buyers often source it for projects requiring stable water delivery in remote areas with abundant sunlight but limited grid access. Trade terms such as MOQ, lead time, and packaging are confirmed directly with the supplier, as these are not specified in the listing.
