The Veichi 18kW (25 HP) Solar Pump Inverter is engineered for reliable solar-driven pumping in agricultural, irrigation and remote-water applications. It integrates advanced MPPT, vector motor control and pump protection functions (dry-run, low-frequency, over-current, minimum-power protection), enabling efficient direct-drive of submersible and surface pumps. Compact, easy to commission with multi-language menus and RS485 (Modbus) communication, the SI23 series delivers stable pump performance and improved energy harvest for off-grid and hybrid systems.
Typical applications include irrigation, livestock watering, potable water supply, and remote pumping where grid power is unavailable or expensive.
