Solar pump Inverter For Water Pump 2.2kw 4kw 5.5kw 7.5kw 11kw 15kw 18kw 22kw
1. Cover voltage levels 220V AC and 380V AC.
Support single-phase 220V and three-phase 220V/380V pumps,the power from 0.4KW to 37KW.
2. Easy to use
The inverters automatically start or sleep only after being connected to solar battery panels without any parameter setting.
3. Highly reliable for using multiple protective measures
Including PV over-voltage protection,PV polarity reverse warning,and auto derating against over-temperture,which extend product life.
4. Use advanced MPPT algorithms,ensuring that the solar power tracking efficiency reaches 99%
5. Models of 2.2kW or lower can be configured with boost module,meeting low-voltage work requirements.This reduces the use of solar battery panels and therefore the cost.
6. it can implement auto switch between solar input and grid input by configuring the boost or auto switching cabinet(meeting lightning protection requirements),implementing 24-hour unattended work.
Accessories:
1. GPRS (support 2g/3g/4g internet)
It supplies water volume monitoring and operation of inverter from anywhere at anytim
It’s convenient to visit real time and historical data via web or Android APP anytime and anywhere.
This easy-to-use platform makes monitoring of solar pump systems simple and convenient,
far reducing operate time and monitoring costs as well.
2. LCD keypad
Standard inverter are with LED keypad,LCD keypad is optional.
LCD keypad can monitor 4 parameters at the same time. LED keypad show one parameter only.
LCD keypad with detailed parameter explain,no need use user manual ,more user friendly.
LCD keypad with copy and update and download function.widely used for government projects and big farms.
3. Output Reactor
When the distance between inverter and pump is more than 70m, you need use reactor to protect this system.

Technical Questions and solutions
1. How to achieve Automatic start after stop?
If it is controlled by keyboard no need to set any parameter. If you want to control by external switch
As the default control mode is keypad control, First set P00.06=1 and use a wire or switch to connect com and DI1,When the switch is closed, the drive run, when the switch is open, the drive stop
2. How to use a float in the water tank to stop the pump if the tank is full?
If your float signal is digital signal Use float switch to short DI 1 and com and P00.06=1
3. How to design solar PV water pump system?
Key point: the rated VOC and VMP and power of the PV Array need to match the input range of the inverter. If needed, we will provide technical support online.
