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…

Alternative to spray foam?
Hi So I've seen this https://www.mortgagestrategy.co.uk/news/spray-foam-insulation-leaves-250000-homes-in-mortgage-limbo/ So, I really wouldn't want any spray foam insulation. What's a better form of insulation? One that doesn't have other issues down the line?

Solar Panels
Hi not sure if I picked the correct category but I hope someone can advise me. We have solar panels on the house. It was my husbands pet project and I was not involved at all. He died last year and it has taken me a while to sort things out. I discovered he had no paperwork so I had to get that and I have found out they…

Seeking opinions about solar quote please
I hope this is the right place for this. I hope I can get advice on whether this quote is reasonable cost-wise, but also whether it is the best system for us? We are fairy low electricity users and this system seems to be geared to us producing excess to export to the grid and thereby be paid, so that gives us a bigger…

As part of choice of house, we wanted to install a solar and battery system on the property. We will also be looking at if it is a suitable property for replacing the gas boiler with an air source…

SK-SU3700E off grid don’t charge battery is EPS is off
Hi I am not sure if I posting in the right place. Please let me know. I have a SK-SU3700E to use off grip in a garden room which I can’t have power from the house. I bought this hybrid inverter without checking much about the specs and manual because it was a bargain (I think) and I had no time to look for more information…

The largest system I've seen!
Thought I'd share what 52 bifacial rooftop panels (paired to 2 X Tesla PW3 battery inverters) looks like! DNO export permission for 22 kWh approved, also the highest I've been involved with! Expected annual generation is 20+ mWh!! :o

Solar/battery customer service
How many of you have found, after investing in a solar array and storage batteries getting any form of advice and customer service from the installer or the hardware manufacturer has been nigh on impossible? We had GivEnergy batteries and inverter installed followed by a very rudimentary introduction by the installer on…

Givenergy woes

Unfortunately this lasted for a very short time (Installed on 25th May and dead on 8th June) AC coupled inverter 2* 8.2KWh batter Roughly 10 days ago, I was checking the EPS (backup power…

Exporting as much as possible
we only need hot showers at 7am and 9pm . I disconnected the sender unit from the meter and put the offset at 500w which is the max. I have decided to divert as much energy as possible to my 'spin back' old fashioned meter . I heat the showers from gas which is cheaper . Is there any more I can do to save money ? We have 8…

Tesla PW3 Rebate Extended till June 30.
From the horse's mouth - the rebate program has been very well received by Tesla Certified installers & end customers alike, and so it has been extended till 30/6/26. Personally, I believe it's a promotion aimed at keeping the PW3 competitive while Tesla prepares to launch best in class energy tariffs aimed solely at…

Lux ac battery controller
Thought I'd start a new thread for the Lux battery controller as suggested on the battery storage thread. To kick it off, I notice there is an entry on the web portal stats under "history data" for battery temperature (tBat°C) but mine just shows zeros. There's also entries for max and min cell voltage but again, no…

When I asked Octopus for their cheapest tariff I got an email back asking if I had solar panels and a battery. I do have solar panels but no battery. What difference does it make. Would my tariff be cheaper if I didn't have solar?

Octopus Virtual Power Plant
As my Powerwall 2 failed, Tesla finally replaced it with a Powerwall 3. This led me to opt for being part of Octopus's Virtual Power Plant. So far I am not convinced of the benefits. I fear that my battery is being drained and recharged in ways that do not offer me as much as when I had fixed Octopus rates for import and…

Adding a battery to existing solar.
So, after about 2 years of having my solar panels, I'm comfortable with the system and my usage patterns. I'm currently exporting with EoN, at 16.5p, which seems to no longer be available. So now I wonder if there's going to be a general trend of SEG payments decreasing (as more people adopt solar and sell excess power),…

Basic Solar Question - Consumer Unit
Just in the very early stages of thinking about Solar and was wondering if access to the consumer unit is a must have, or can the connections just go to the meter/input which is outside. The house has relatively newly laid Kardeen flooring, with insulating boards under and I have no desire to lift and then replace them as…
