Installed equipment different than quoted.

stuhow20

Hi, I had a solar package installed but have realised the inverter is a different version than quoted. 

The sale went as follows:
salesman visited and quoted for a system, we agreed and paid deposit. (No equipment details given at this stage)
formal quote listing all equipment and savings etc. We accepted and signed, install date arranged. 

Install took place and final contract was sent through and signed. Again this stated all the equipment. 

We then had a dispute with the company and was given compensation and a new contract with the new amount was sent and signed. This version has a different equipment version. 

Company are saying the original quote and contract was a data error as the version stated wasn’t even in production. This has been disproved by the manufacturer by email. 

So question is where do I stand given the original quote and contract signed state a different inverter than was installed? The one stated offers better output than the one installed. 

Thanks.

What do you class as "better output", do you mean higher rated maximum output, higher efficiency, something else? Are they broadly comparable and often used interchangeably, eg. One has a max output of 3.81kW and the other 3.79kW?

If there is a difference which makes it worth pursuing thr you could take the route of asking for more compensation, trying to require them to fit the original etc. though it will depend on contract and the differences etc. Especially as you have now signed the new contract.

Just to clarify…original contract was not fulfilled, there was a dispute, you received compensation.  

Then a second contact was drawn up and signed and agreed?  Is the installed equipment as detailed in the second contract?

Yes one outputs 2.6kwh from better ones the other 3.6kwh

Amended contract was signed after tge installation and just states the make of inverter and no G2 as the original and quote.

Not sure if you felt that was a clear answer to the question (or if you weren't attempting to answer that question), but is the installed equipment as detailed in the second contract?  If you've signed a contract that supersedes the original one, then what was originally quoted becomes much less relevant, if at all.

Maybe worth amplifying on the dispute and compensation, in terms of whether the supplier was effectively compensating you for installing the inferior specification?

I think if you've signed a new contract following a dispute and received a discount and the new contract shows the equipment that is actually installed then you are going to have difficulty making a case for anything more. If I was the installer I would argue that you signed off on the new contract and agreed to the spec shown there. Which is going to be difficult to counter unless you have something explicitly stating otherwise?
