System Design Recommendations
- Solar panel power should be 1.3-1.4 times higher than solar pump power
- Solar pump inverter power should be higher level than solar pump
- For distances over 100m between pump and inverter, use output reactor or higher power inverter
- Solar panel total VOC must be less than maximum DC voltage of inverter
- Recommended solar panel VMP: 305V for 220V pump, 530V for 380V pump

Product Applications
Frequently Asked Questions
Automatic Start After Stop
For keyboard control: no parameter setting required. For external switch control: set P00.06=1 and connect wire/switch between COM and DI1 terminals.
Solar PV Water Pump System Design
Key requirement: PV array rated VOC and VMP must match inverter input range. Technical support available online.
Float Switch Configuration for Water Tank
For digital float signals: use float switch to connect DI3 and COM terminals as shown in wiring diagram.
Frequency Range Setting (e.g., 30Hz-50Hz)
Set parameters P47.05=30Hz, P47.06 and P47.07 to appropriate timing values.
60Hz Motor Frequency Configuration
For 60Hz rated motors: set P01.06=P01.08=P11.05=60Hz. Quick setup: set P00.11=02 for three-phase motors, P00.11=22 for single-phase with capacitor, P00.11=32 for single-phase without capacitor.
