Inverter replacement (?) - Newcastle
Can anyone please offer me any guidance with who I should contact to check my current set up? We had our solar array installed in 2011, so receiving the fit generation payment, and it is still using the original Sunny Boy inverter. The installer has long since gone bust. Everything has been working fine until recently when…

I’m really disappointed with Sofar Solar right now.
I’m really disappointed with Sofar Solar right now. My ME3000SP inverter was bricked by their own latest 3.60 firmware update — a firmware version that has known issues and has caused the same failure for other users. I contacted Sofar for help, but because my warranty expired in 2024, they’ve refused any support at all.…

Renewables: "talking 'bout my generation"
Please forgive the corny thread title inspired by The Who but this post on the bloated 'how do I make the most of it' thread prompted me to initiate a new one... Well, there was yet another misty and bleak start in North Notts today (Thursday), but my SSW 3.92 kWp system was generating around 3kW for just a few minutes…

Solax self use and export settings
Need a little help regarding the export side of Self Use mode for Solax Inverter. We have 10 panels on roof ( don’t know any more than that) with a Solax X1- HYB -3.7 Inverter and also a battery. The system have been in and up and running for year and all was well. From Feb 2026 we were getting Outgoing Octopus payments…

Growatt Battery Setting Help
Hi all. Now that the days are starting to get longer, although not long enough yet, I'm looking for some advice in regards to the battery settings on a Growatt. Since the Solar and battery has been installed, I've been charging the battery using a cheap overnight tarrif (Intelligent Octopus) and then discharging the…

Ashadegreener
Hello, My sister has had "Rent a roof" free solar panels from a Shade Greener fitted some 12 years ago. She doesn't believe she is seeing any gain and has had Octopus engineers check meters etc. and nobody can say that all is OK. Comparing her electric bill to the bigger family next door (hers is roughly the same if not…

CT Clamps - some Qs.
Well, got all my bits, and now just need to join them together; 3 of 5.7kWh Alpha-Ess batteries, Sofar ME300SP AC-coupled inverter, and all the gubbins. The two CT clamps have short wires, so I need to extend them. I understand Cat cable is good for this. Q1 - for neatness and convenience, can I share the same Cat cable…

Alpha Ess M48112-S 5.7kWh - 'Commercial/Industrial' designed for series.
But any reason they won't also work in a domestic situation in parallel? I think the essential Q is, will the COM port communication be compatible with a domestic AC-Coupled inverter/charger such as the Sofar ME3000? https://www.alpha-ess.co.uk/images/datasheet/M48112-S.pdf

Ripple Energy wind farm?
Has anyone looked at Ripple Energy? I'm thinking about it, but not too seriously. I don't have a lot of time to investigate it and if anyone else has taken a look I'd appreciate their thoughts before I take a more serious look.

Battery Electric Vehicle News / Enjoying the Transportation Revolution
I thought a more specific thread/title might be useful for posting news on BEV's (and EV's in general), given that we have threads to discuss the minutia about EV ownership, but perhaps a thread just for the news might be useful. Disclaimer from the start, BEV news can easily become Tesla heavy, so posts, especially mine,…

Solar panel and battery quote
We are looking at getting solar panels and battery. We can fit 4 panels east and west facing and 3 panels south facing so 11 panels overall. We had a company out who suggested a 9kw battery and advised getting a bigger inverter of 7kw to avoid issues using oven/kettle/tumble dryer ect together. This was their suggestion…

Consuming excess solar with smart plugs?
Hi all, I've recently had a 4.8kw solar system installed, I decided against a battery and hot water diverter due to cost and value for money. My inverter is a Solis S6 and has an app to monitor generation but not it seems consumption. I am currently using my smart meter to keep an eye on the exported energy. I'd like to…

New Plug-in Battery, no electrician required
Just stumbled across this. Pre-order £699 for a 2kWh battery. sounds interesting, capacity a bit small, but might suit someone - certainly I'd think a shed with solar on top might benefit for outdoor supply to the garden. https://www.nodienergy.com/

8.5 kW Bifacial PV System: ~7 year ROI: Fact OR fiction?
Updated system size is 8.45kW at a total installed cost of £10.5K. Current ROI is forecast at 6.5 years. Hi there, I've recently been quoted for solar panels from 3 installers referred by Solarguide. My guidance to these companies was maximum solar power yield per panel for their proposals. Quote: The LG panels are dual…

Solar Panel Quote
Hi, currently in the process of gathering quotes. I have received 2 x quotes so far, one from EON which I have already discounted and 1 from a local installer, no site survey from this one yet (see below). I have emailed this guy back requesting requote for 10 x panels and a 5kw inverter. I have just had another local…

Cost of adding batteries to existing PV system.
I'd always shrugged off doing this as the return time would be too long. But I've recently seen some near-new battery setups being sold on FbMarketplace for prices that are hard to ignore - sometimes as little as £1.5k for excess of 10kWh. The Q is, what would the additional costs be should I jump? Ie, installation, and…

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…
