KEY ADVANTAGE
1. Cover voltage levels 220V AC and 380V AC.
Support three-phase 380V pumps, the power from 4KW to 11KW.
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. 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.
7. Support the configuration of the GPRS module, which implements
remote parameter viewing and control by using the mobile APP.
8. Support the cabinet solution for level IP65.

Applications
Q&A
No, it doesn't. The inverter has a self-adaptive and self-learning
function. It is automatic start and stop, you can press Run key to
start, or you just wait for 600S then it will automatically start
2. Could it replace my previous PV pumping inverter?
Yes, of course. Selecting inverter model according to the rated
voltage, current and power of the water pump. A bit more is better.
Then take off the old one and put ours on, the system will work.
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 need, we will provide
technical support online.
Usually, solar PV water pump system can meet the needs of pumping
water.
If there is no sunshine, the system will not work. But out inverter
could also support AC input. So, connect the power grid or diesel
power generation to the inverter, the pumping system will work. If
necessary, keep switch and interface locations during the system
design time.
5. How to use terminal control with external switch to run and stop
solar pump inverter ?
(Terminal control): 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
6. How to use a float in the water tank to stop the pump if the
tank is full?
Use float switch to short DI 1 and com.
7. Use level probe in the well for protection against dry running
Set P24.12=1 and set P24.13 and P24.14 and P23.21
8. How to set minimum frequency 25hz and maximum 50HZ?
Set P47.05=25HZ and 47.06 to some time and 47.07 to some time
9. If pump is 60HZ frequency, how to set max frequency?
Notice:If your motor rated frequency is 60HZ you should set
P01.06=P01.08=P11.05=60HZ.
10. How to achieve Automatic start after stop?
Our solar pump inverter is automatic start and stop with our
special software
