Heheh!Oh got it house plus 2x EVs, I was imaging 120kwh of home storage, makes more sense now
Solar panels and battery - any real world reccomendations?

We had a very short power cut today. We can't afford to lose our heating and office in a power cut so we specifically requested islanding. Is it possible to tell from the schematic/proposal if batteries will definitely power the house in an outage? (I'd love to share the diagram but I don't have a website to share it from.)
Edit: they said it would, but I don't trust so easily!

Go Faster is the 21:30 to 02:30 slot onwards, so you get 5 hours at a sensible time of day, when a great deal of people are still awake and using higher drain appliances while not depleting the batteries as much. This means on a predicted (or actual) poor solar day you will have more power left for the morning/daytime in the house batteries. It also gives you an extra hour to charge larger battery car(s) which is an extra 7kWh per car. Downside is 8.25ppkWh.
I had an old work acquaintance contact me yesterday, he was due to have the following installed on Friday.
Does the Fox system integrate with Octopus?
Which is the better system?
Is one significantly cheaper than the other?
He's asked me not to disclose the cost, but its steep even for now, he was quoted early July.
- 15 x Perlight Solar Panels 400w Black Mono
- GivEnergy 5kW Hybrid Inverter
- G2 GivEnergy 9.5kWh Battery
- Perlight Solar Panels 400w Black Mono
- Fox H1AC presumed 5kW Hybrid Inverter
- Fox HV2600 presumed 9.7kWh Battery

Those fox batteries look quite expensive
I think they were what one of my installers said was an option if I insisted on inside rather than outside, more like rack mounted, in fact if its them he said they would be in effect a wall mounted rack system
If they are the ones he was indicating to me better than givenergy but then you never know with installers as whatever they can get will be the best right

Solar powerful out of clanfield did mine and @HungryHippos and suspect they cover your area. Whether they have the time to come is a different matter.

11k for 18 panels does that include a battery? If not then that is expensive.
Solar Dynamics are based in Horsham and should cover your part of the world.

Stick with Givenergy - the missing cables are the fault of the installer, not the supplier. It pretty clearly says on every order that you need to order appropriate cables.
Reason for this is the Gen 2 devices have different cables, so you need to pick the right combination.
18 x 415w Jinko mono panels (JKM415N-54HL4-B), 18 x enphase IQ7PLUS-72-2-INT, enphase envoy, bird guards and 2 storey scaffolding.
They quote another 10k for a Tesla powerwall (which seems about a grand or so over expectations).
Will take a look at solar dynamics thanks
Yeah the FOX stuff is OK, the batteries will be 4x 2.6kWh modules (they look like server rack batteries) but only have a 90% DoD, so the capacity would be 9.36kWh, so a bit more than the GivEnergy single battery, it also uses an external BMS. I'm not sure if the inverter is compatible with Octopus or any ToU tariffs, but I'd be asking them for the 6kW version the FE-H1-6.0 since he'll have 6kWp of panels, it about £20 more than the 5kW version..

Prices are just ridiculous right now it seems. What's the point in paying so far over the odds? I'll wait until things are a bit more sensible.

What do you consider over the odds?
My system, £13k I just ran the numbers on with revised cap this week. Assuming i get close to generation and charge in batteries gives me 6.25 years payback,
I have 2 years almost baked in with the current cap and expectations.
Thats ignoring my contribution to reduced fossils usage!
With energy at that level I think demand is going to stay similar to now for 2 years and in 2 years time who knows what the going rate will be.
Unless we see significant government rebate to costs (which I doubt) its hard to see them being significantly cheaper, and in the mean time I can pay around £1k for my elec usage as opposed to £5k I predict at 34 pence cap.

Prices are higher than they used to be, which is true of most things (Supply and demand, evil corporations, pandemic, etc etc). Those of us who don't want to wait and hope, must watch out for companies charging more than others are for the same thing at the same time.
I don't see how prices of energy or domestic renewables could drop within the next year. If they do all all, it is more likely to be 18 months+ and we can't wait for that. Any vendor with business sense will keep costs high to recouperate pandemic losses and save up capital.

I do feel the same. I am happy with the capped prices for now considering where they were headed.
Going to see what's what in 12-18 months time. Might be a bad choice if thinks kick of with China over Taiwan though, but that might be the least of our worries if that happens.
Inflation is running at 10%. Prices are only going one way.
That is another issue i forgot to mention in my post. But being a relatively lower energy user I can offered to take my chances I guess.
