I have received great advice over the years from this forum and am hoping for some more.....
We have a Powervault P3 4Kwh battery attached to our 8kwh solar panels and would like to add 2kwh more. During the installation (3 years ago) Powervault assured us that this upgrade would be a simple 'just plug them in' process, but when we approached them fo a quote they want £4,000. Yes, you read that correctly. Our whole battery system originally only cost £3,500 so I am stunned that 2 more battery packs can cost so much. Is this right? If so, is there a way of just buying the same batteries online and getting them installed by a local PV specialist? Does it have to be a specialist or is it as simple as opening the cabinet and plugging them in.....? Will Powervault notice, and if so, will it matter? Thanks all.
