How do PV charger/inverters 'control'?
In very basic terms! I remember asking the installer at the time how the system 'knows' to prioritise supplying the house over the Grid, and he explained the inverter constantly monitors the exact grid voltage, and 'ups' the supply from the PV system a tiny amount to override it - the system therefore supplies the house…

Solar quote confusion
Apologies, have been reading up but still fairly new to all this. Have contacted a couple of online companies and also a couple of local ones who have done site visits and I'm kind of surprised at the difference between what they are all suggesting is suitable. Even down to the placement on the roof some seem to be pushing…

Solar & battery tariffs and how to get best export rates?
Im contemplating a 10 panel solar pv, 15kwh battery and 5kwh hybrid inverter. Ive got my quotes and researched the component parts so am not looking for comments that 'you're better using this make' etc, etc. Ive no intention of getting a heat pump and getting an EV is very unlikely. As Im nearing 70, the faster the…

Battery only install
For now going for the cheaper option, as solar is out of our price range. Average usage is around 6kWh a day peak time. I know payback is not as good as solar (not that I'm worried about that), but needs must & will make a nice saving a month on bill, charging overnight on IOG, which we are on with 2 EV's & not wanting…

Growatt Solar batterys?
Does anybody rate Growatt solar batteries? I'm looking into getting a solar pv system with batterys, have been quoted by one company which are offering 2x6.5kw batteries as part of the package. Bit hesitant as I understand their inverters aren't great and their customer service is non existent?

The Iran Impact: Panel and Battery Inverter Prices rising from 5/26 onwards
Just received confirmation from two of the installers I use. Component prices are rising across brands, which will impact new Solar quotes from May onwards. As an example, Tesla distribution had 700 PW3s in stock in early April. Last Friday, < 100. Said another way, the UK will likely sell out of Tesla PW3s by month's end.…

North Wales solar panel quote
For info I went direct to eon for a quote to solar panels before reading a lot of the posts here so am aware that the brands quoted are not always recommended, but would welcome any input to this quote. I am a little unsure where to start with getting an independent other than just pick a company registered with the Mcs…

Our very own @QrizB gets a mention in the FT
While I don't believe the battery ownership experience needs to be as agonizing as the journalist's experience clearly has been, I do hope that more home battery owners will exercise more diligence when deciding whether a battery, and perhaps more importantly, which battery is the right decision for their households. Link…

Aurora Inverter Decode
My solar panel system is controlled by an Aurora Power One inverter fitted approx 6 years ago. Can anyone help me decipher the various messages that flash up on the screen display. The serial no is of only passing interest, I am more interested in knowing how much power the unit is producing at any one time and whether I…

I'm in a quandary. We are a household of two, mostly at home all day. The property is in Cornwall with no obstructions. We only use 2000 units a year electricity (with effort) and 4000 gas. We have no EV and no plans to get one for a few years but had no power for two or three days last year because of the storms. Eonnext…

Which storage battery
Hi all, We have recently had a 12kW ashp installed in our 4 bed house (4 of us); prior to this we were reasonably heavy users anyway using anywhere between 5-15kW. Currently we’re between 15 and 25kW and this will obviously increase in winter. I have just started to get quotes for battery storage; we also have solar panels…

Help with battery choice
I have a house with a 3.9 kWp FiT PV system. We are about to start major renovations and as part of that will be installing an ASHP and UFH to replace an LPG boiler and ancient radiators. Now would seem to be the right time to add a battery, and possibly replace the old solar panels and increase the PV generation. I have…
