Well dear reader, it’s been determined by the inverter manufacturer Fronius that it is cactus and needs a replacement. It wasn’t something that could have been mended, which was disappointing to say the least.
Something else that’s come to light is that due to electrical regulations for solar PV systems, the isolation switches have to be replaced. As well as that, due to the inverter being completely replaced, the system has to be inspected again.
So here’s the quote by Energy Matters (aka SunEdison);
|Item||Cost (incl. GST)|
|1x Fronius Galvo 3.0 Light||$1881.00|
|4x DC Isolators||$933.97|
|1x Earth Fault Alarm||$7.24|
|1x Label Kit||$79.21|
|Service (labour, shipping & installation)||$385.00|
A fair bit out of pocket, and I estimate that it will need at least 3½ years of operation to pay itself back. Not too bad, but it was certainly not an expense I expected after only 9 years of operation.
I will have to draw down on my mortgage to pay for it, so that means I have to work longer to pay it off. Swings and roundabouts I suppose because it has been due to our very low electricity bills since 2007 that we’ve been able to pay down our debt rapidly in the first place.
The only way to proceed is forward, so I’ve asked the work to proceed. Once the installation starts, I’ll give you another update. Hopefully nothing else goes wrong in the process.
