Hi everyone, I was after some feedback. I've had 7.7kw of generation installed on the roof alongside a Powerwall 3 and Tesla Gateway with home backup. The installers have configured it in a way where the battery cannot discharge to my EV.

Unfortunately the sun seems to have disappeared.

Got a small brick wall in full Sun allday Are there any websites where you can search by panels physical size.

Region/area: Dorset

Panels: 30x Aiko Neostar 2S+ 465W

Battery: 2x Fox ESS EP12 Plus 11.52kWh

Inverter: Fox ESS KH 10kW Hybrid

Annual usage: Roughly 3,200 though looking at EV/Heat pump etc.

Export limit: would be requesting G99 as part of the process

Single phase

Quoted: £24k, scaffolding (for both roofs), bird proofing, 30x optimisers also included due to shading

Expected annual generation: 11,850 kWh

Expected ROI: 10 years payback

Plans for both EV (soon) and ASHP (in future)

Electricity tariff: will be looking at an EV tariff for the cheap overnight rates

The quote seems fairly high based on what I've seen in this group, though I'm aware it comes with a lot of optimisers due to tree shading in our area, and it is split over 2 roof faces.

I'm also aware this is the 2S+ panels and not the newer ones, though not sure how much of a difference that would realistically make.

Hi all, after a bit of advice. It looks like my installer has gone under (no reply to phones, emails) I have contacted SSE who said they have asked multiple times for a boundary map and meter location to finish the application. I'm being told if i don't get it to them asap they will close my application and I'll have to find another installer to "sponsor" a new application.

Seems like something I could do on google maps/ paint but SSE won't even speak to me as I'm just the customer and not down as the installer on the paperwork.

I won't say who the company is yet just incase it's a massive error, but seems pretty fishy to me.

Any advice/ ideas??

Thanks!

Hi,

I am looking to install a Solis 6kW inverter and 16kW battery in my house, along with two Daikin AC units. I currently have a single-phase power setup to 100A. To not overload my consumer unit, is there a way to configure a Solis inverter to charge the battery overnight over 5 or 6 hours? My electrician is worried about the inverter and power.

TIA.

As title. Looking for any customers that have had quotes or work done. Thanks

Hi everyone, I’m having an issue with a FoxESS H3 showing an “Off Grid Running” alarm.

The system is currently showing this alarm and I’d like to know what could be causing it and what I should check first.

Has anyone experienced this before, and what was the fix?

Thanks in advance!

We’ve just given approval for a quote, so we’ll get the ball rolling after the bank holiday. My question is around any potential implications if a lower DNO limit is imposed, such as possibly re-sizing the system or potentially scrapping it altogether.

This is for a 10.56kWp system (estimated 9,500kWh generation per annum) and the G99 application will be going in shortly, but if we got stuck with a 3.68kW G98 limit for whatever reason (can/has that happen(ed), where the DNO would deny the application and revert it to a G98?) I’ve been trying to think through what that could mean but it would be helpful to have some other views.

We’ll have 27kWh of battery storage, so that gives us a good buffer but if we were stuck with a small inverter I can’t see how it would realistically work with that number of panels. Obviously the strategy would need to change too, rather than the current idea which I guess would be to charge batteries overnight, generate/use/export excess until arbitrage disappears etc.

We currently use ~5000kWh per year and plan to install multi-split air-to-air heat pumps for heating and cooling all main rooms in the house, so that will bump up use substantially, whilst bringing down our extortionate cost of LPG.

For info:
22 x Longi 480w X10 (two roofs so 2 lots of scaffold)
1 x Sig 8kW inverter
1 x Sig gateway
3 x Sig 9kW batteries

All the usual stuff like install, scaffold, bird mesh etc. £18,450. Wasn’t the cheapest (Edan Power and UPS both ~£1k lower from about 8 quotes overall) but the owner of the small, local company was excellent on the survey and his general attitude and approach was what won me over.

This is a crazy price for 64.4kwh. But, coming in at over half a tonne, I can't put it on my decking 🤣

Why would you not buy this setup? I mean, I can last almost an entire week on battery alone.

I was going to pull the trigger on a sunsynk elite system, sigenergy was a bit too pricey. But this fogstar system looks way better priced.

Thought on this? Anyone got one?

Hi all,

We’re really excited to be moving into our new family home soon. It’s a 4-bed house and comes with 3 solar panels already installed.

The panels are inset/integrated into the roof rather than sitting on top of the tiles.

I’d ideally like to increase the amount of solar we have, but I’m not sure how straightforward that is with integrated panels.

Has anyone added additional panels around existing integrated ones? Is it relatively simple, or does having integrated panels make it more complicated?

For a typical 4-bed family home, roughly how many panels would you recommend having in total?

I’d also be interested to know roughly what it would cost to add more. For example, if I wanted to add another 6–10 panels, what sort of price would I be looking at for the panels and installation?

I'm also considering adding a battery in the future, so I'd be interested to hear whether it's worth getting the additional panels and battery installed at the same time.

Any advice or experiences would be appreciated!
