managing battery inverter output.
I realise that there are Battery Management Systems but I could be wrong that they only control input? I am currently planning and installing extra solar generation capacity (about 2.5kWp max) following purchase of an electric vehicle (phev) and Zappi. At many times there is sufficient spring to autumn excess to charge the…

Cost of living reporting
Listening to the news this morning, I have been pretty shocked by people's misunderstanding about energy savings. For example, one person said it would cost £6 for a tumble dryer load - which would work out at 20kwh! Another lady said she could not afford to charge her electrical wheelchair every day - which surely must be…

PV home battery storage and EV charge point conflicts.
I couldn't find an answer anywhere on here, If I have a Hybrid DC coupled battery set up with my PV, when I plug my EV in at night what's stopping the EV from emptying the home storage battery? I've seen how this can be avoided with the Zappy by using the export margin but I'm talking about a bog standard wall point. Is…

I have two options for the portrait panels on the side roof: 1) 1.85m (395w) panels. Which would result in eaving a 0.17m gap to the…

Sorry, put this in the wrong place
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,…

Solar panels on single story extension flat roof - permitted development?
Hi All, I am reading the permitted development rules for panels which states they must not protrude more than 200mm from a roof surface and not go over the top of the roof (excluding chimney). I already have a set on my pitched roof. I have space on a single story extension (the house is 3 story) for extra panels. Since…

Adding batteries to existing solar system
I have a 4kw solar PV system thats about 10 years old and was toying with the idea of adding battery storage to it. I have a quote for a 4.5kw battery and hybrid inverter £5500. The company say that using it I will pretty much not use any electricity from the grid. Seems a bit far fetched to me. What kind of saving on my…

Low flow temperature radiators
If you buy these, for gas boilers, could you then switch them to electric quite easily down the line? Right now, the house I'm buying, has a brand new gas boiler largely because their old one broke. Doesn't then seem worth doing much until 2035, but if I can slowly switch over by having better radiators for heat pumps…

Solar PV installation companies - Greater Manchester?
I filled out a form on Greenmatch, and Evergen keeps coming up as a company, but the reviews from Evergen are quite shocking Does anyone know of a decent company that fits these in greater Manchester? Along perhaps with battery storage I've decided against heat pumps for now, largely because the COP isn't comparable with…

Suntech vs. Hyundai 400W panels
Got a chance to inspect both brand's black panels up close and personal and was surprised at the difference in quality. Both are 400W but Hyundai (made in Australia) was the clear winner despite being less expensive and having a better warranty. See for yourself below: HYUNDAI REAR SUNTECH REAR HYUNDAI FRONT SUNTECH FRONT…

We are thinking of adding a battery, a hybrid inverter and a few panel to our FiT registered installation. The output from the additional panels will be kept separate from those on the original installation to keep the FiT safe and we will be replacing our ageing inverter with the hybrid. Can anyone recommend (from…

Inverter downsizing - Looking for advice
Hello, I'm in the process of having a 5kwp solar pv system installed. The installer had initially said they would install a 4.5kwp solar edge Inverter, but after looking at the Inverter model online they've installed a 3.68kw Inverter.

My wife and I are really interested in getting solar panels, partly to save some money but mainly to lower our reliance on fossil fuels. Our house has two roofs, one adjacent to the other. One is flat and the panels (8) can be orientated directly south with no shading. The other is pitched and faces slightly south west…
