Replacement inverter needed - is this a good quote?

Hungerdunger

In 2011 I had a 9.4kW ground-mounted system installed consisting of 38 panels with two inverters each of which takes power from 19 panels in two strings. Recently I noticed that the output from one of the inverters was roughly half of the other one, and a local installer (not the original one who has gone out of business) worked out that both strings are generating power, but the inverter is only accepting power from one input. Anyway he decided it needs replacing and has come back with a quote of £960 (including VAT) which includes installation, 5 year warranty and his original call out.


This sounds a lot to me but if anyone has experience of recent prices of similar equipment I'd appreciate some feedback. The faulty inverter is an Eversolar TL5400. Rated AC power 4600W; Max AC power 5060W. The installer has recommended a Solis 4.6kW inverter.


The other thing which concerns me is that he didn't know of any local businesses who might be able to repair it and had no idea whether a repair might be possible. With any other piece of expensive electrical equipment I'd be getting someone in to look at it first, but it appears that at least in this part of the world (Carmarthenshire) it's not possible.

I paid £580 inc vat for a replacement 4kWh sofar inverter.

Ebay suggests the solis 4.6 is around £550

It depends a bit on how much you think the installation should cost and whether you feel competent to do it yourself. You're not going to get a 5 year warranty with an inverter bought off eBay and it sounds as if you will be charged for your original call-out regardless.
