Product Application
FAQ
1. Does the product need to set a lot of parameters?
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 P47.03=600S(Default) 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 needed, we will provide
technical support online.
4. How to make the water pump system work without sunshine?
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
