VEICHI SI21 1.5kW Solar Pump Inverter 150-450VDC
VEICHI SI21 1.5kW Solar Pump Inverter 150-450VDC
VEICHI SI21 1.5kW D3 Solar Pump Inverter is the 150-450VDC configuration for photovoltaic water pumping. It converts PV DC power into controlled 220V-class three-phase AC output for compatible pump motors and uses MPPT control to maximise available solar energy.
Key Features
- MPPT solar-power tracking for photovoltaic water pumping.
- Variable-frequency control for compatible pump motors.
- Pump functions include dormancy, dry-run, low-speed and water-level control where configured.
- Supports compatible asynchronous and permanent-magnet motors.
- Optional IoT hardware and monitoring functions depend on the ordered configuration.
