Solar panel power should be 1.3-1.4 times higher than solar pump power, and 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 inverter maximum DC voltage.
- Built-in EMC C3 filter with advanced software and unique design
- Compatible with single phase, three phase, and permanent magnet synchronous pumps
- Dual input support: PV and AC input simultaneously for 24-hour operation
- High-efficiency MPPT technology with up to 99.9% efficiency
- Water level detection with automatic flow regulation and dry-running protection
- Water full protection function for system safety
- Optional LCD keypad and GPRS module for easy operation and monitoring
- Built-in soft start, overvoltage, overload, undervoltage and weak sunshine protection
For keyboard control: no parameter setting needed. For external switch control: set P00.06=1 and connect wire/switch between COM and DI1.
Key requirement: PV array VOC and VMP must match inverter input range. Technical support available online.
For digital float signals: use float switch to short DI3 and COM terminals.
Set P47.05=30Hz for minimum frequency, with timing parameters in P47.06 and P47.07.
Connect power grid or diesel generator to inverter AC input for continuous operation during low sunlight conditions.
Check solar panel VMP/VOC, motor power/current, distance between motor and inverter, trip records (R25.00-R26.03), and motor insulation/blockage.
