Option 2: Get the JFY Solar Inverter Repaired
This is where we can help.. the process is straight forward. You will need to arrange for an electrician to get the inverter off the wall and into a box; once done we will arrange a courier to pick it up and send it to us, we will fix it, and have it sent back to you – the whole process takes about 14 days from pickup to drop off.
Below are some of the most common JFY inverter faults we find:
Output Relay Fault
The output relay fault is a very common problem; sometimes it means the relays need to be replaced, sometimes it will be the output filter capacitors collapsing; either way the inverter will need to be sent to us for repair. When we repair the relays we use OMRON relays, there are a robust industry leading relay and will give much better service life.
