Option 1: Purchasing a new Inverter to replace the Sunnyroo.

If you decide you want to purchase a new inverter, then we suggest the following inverter choices. We base this on knowing the inverters below will just plug straight into your existing Sunnyroo installation, which means your electrician will easily do the swap over for you.

Sunnyroo SR1500TL – Solis 1.5kW

Sunnyroo SR2000TL, SR2000TLi – Solis 2.0kW

Sunnyroo SR3000TL, SR3000TLi – Solis 3.0kW

Sunnyroo SR4000TLi – Solis 4.0kW

Sunnyroo SR5000TL – Solis 5.0kW

 

Option 2: Get the Sunnyroo 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 Sunnyroo inverter faults we find.

ERR22 - 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.
There is no life in the inverter
By this I mean there is nothing on the screen, no lights are on. This will be the internal power supply on the inverter; the power supply is famous for collapsing prematurely. The good news is we can refurbish the power supply and get it working properly, while we are fixing the power supply we will also make a few minor modifications to it so it will last longer.
AL14 - Utility Waveform error
This is a very complicated way of the inverter telling you it cannot see the mains power supply. The first thing to make sure of is that all of the AC isolators are turned on, there will be one next to the inverter and one inside the meter box. If all of the AC isolators are on then it means the fuse inside the inverter has blown. An electrician will be required to change the fuse because the front cover of the inverter needs to come off in order to access it. It can be found in the lower right hand side inside the inverter. The fuses are quite hard to find, if you cannot source them locally then we are happy to send them out to you.
