- Flexible deployment without grid power limitations
- User-friendly LCD keypad for easy operation
- Hybrid functionality supports both solar and grid/generator power
The solar pumping system includes solar pump inverter, solar panels, and solar water pump. During sufficient sunlight, the inverter converts DC from solar panels to AC to drive water pumps. When sunlight is insufficient, grid power or generators can supply AC power to maintain water pumping operations.
For keyboard control, no parameter setting required. For external switch control, set P00.06=1 and connect COM and DI1 with a wire or switch.
Ensure PV array VOC, VMP, and power match inverter input range. Technical support available online.
Use float switch to short DI3 and COM terminals as shown in wiring diagrams.
Set P47.05=30Hz and configure timing parameters P47.06 and P47.07 accordingly.
For three-phase motors: set P00.11=02; for single-phase with capacitor: P00.11=22; for single-phase without capacitor: P00.11=32.
Connect grid power or diesel generator to the inverter's AC input terminals to maintain operation during low sunlight conditions.
Check solar panel VMP/VOC, motor pump power and current, distance between motor and inverter, trip records (R25.00-R26.03), and motor insulation condition.
