VEICHI SI23 11kW Solar Pump Inverter 250-750VDC 380V
VEICHI SI23 11kW Solar Pump Inverter 250-750VDC 380V
VEICHI SI23 11kW Solar Pump Inverter 250-750VDC 380V is the SI23-D5 solar pump inverter configuration for solar and hybrid AC/solar water-pumping applications.
Key Features
- MPPT controls pump speed according to available PV power.
- AC and PV supply capability depends on the exact D3, D5 or T3 configuration.
- Pump functions include dry-run, low-frequency, sleep and water-level protection when correctly configured.
- RS-485 communication for compatible control and monitoring systems.
- Optional IoT hardware enables additional monitoring functions.
