Ahh yes, i forgot about that.. Very handy for some..

Could you not change to an economy 7 meter (unless thats the meter you have?) and go back to edf on their new rates? (and assuming you have battery storage and dont use peak rate at all) Unless of course you sell back to the grid?, which you obviously couldn't do with the edf tariff..

I spoke to utilita live chat, they told me yes, its all fine. When i call them up yesterday to switch, they say, if you have an economy 7 meter, we are not taking on new customers, and havent been for a year! All their old gen 1 smart meters went wrong and they are having to replace them all...

Thats what i meant by expensive during the day. Only worth it if you dont use peak electricity. For me, based on 8kw a day usage, thats a massive £12 a month max. And thats not taking into account any free solar power being generated. Edit - infact, kinda defeats the point in having...

Also, i phoned octous a month ago and they said they are not taking on any more octopus go customers. A month before this, they told me they were. So best to call them and ask first.. If they are, then this may be of interest: (taken from their octopus go page) (maybe combine with utilita...

Dont think it supports export stuff, but utilita do an economy 7 tariff of 5p kw/h overnight. Expensive during the day, but NO standing charge. I dont export and never use peak electricity due to battery storage, so is far better than octopus go if you never use peak leccy and dont export.

Hi, i have an epever inverter that annoyingly would pull a constant 10w from the grid, but if grid supply was turned off for example, at the breaker, the inverter still runs fine as it should and takes that 10w from the batteries or solar, or just doesnt need to draw 10w at all. So i now have a...

Thanks 👍 ill check them out..

Yes didnt think about that. It would only operate when at a high state of charge, say 3.4-3.45v - but if the batteries were being charged at the time with a reasonable load, that could cause the voktage to be at 3.45 whilst being charged, but then drop back down etc when relay switched on etc...

Yes, a jk bms, not sure if they have their own protocol or use another companies. Thats a definate possibility though... I also have a shunt that has relay control based on battery voltage that i could use, and control it via the bluetooth app. Theres always a way 🤔

Thank you, yes, ive been watching a few videos on youtube about them now, i see they have a clamp meter style device to detect whats going into the grid and then divert that energy to the water tank etc. So, yes unfortunately no good for me 😢. Best option for me would be using a raspberry...

Can i ask, im now having a look into these devices,, do you know if they require a grid tie inverter? If not, do they communicate with the inverter at all? And, if they are supposed to use any spare power from pv, how would it know, for example, that the battery bank is full and i have...

I got my cooking sorted using the 3kw inverter a few days back (thanks santa!) : No need for 4+ kw of big cooker to do the dinner! Got a 550w multi oven and 1200w air fryer to do it all! . With them both running at the same time, and with the tv on, amplifier on, router, phones, top...

Like ive said above, i use cheap rate over night only to charge the batteries when needed in the winter, and i pay 44p a day standing charge with edf. I am switching to utilita as ive found out that they have no standing charge, and 5p kw/h night rate. So, total of £12 a month based on 8kw...

Pretty much, yes, there will be some degredation, but its so minimal, its not worth worrying about. I used to think 20-80% also, based on the very data sheet you have posted, but after much reading and watching videos from people with lots of experience and testing in the real world, i now go...

Yep. The mains are there if i need them, and to charge the batteries overnight in the winter, but thats all. Just want to stop using the power shower as thats the last thing. So will use hot water from the immersion once i replace the element with a 2kw.

For a proper top balance, should always charge to 3.65v to get all the cells balanced as best as possible. Then just charge to 3.45v afterwards. Wont hurt them unless charged to 3.65v many times..

Ok I see.. don't think that will work so well then for me.. Not completely off grid as in the winter I charge the batteries only ever at economy 7 times, currently 8.8p edf(from january). The panels are on two shed roofs, so i was able to diy it. No more space for any more unless i put them...

Ok yes, good point, not sure how that would react. Probably best just to use 2x 1kw in parallel, simplest is usually the best. I guess £80 is worth it, as itll pay for its self in about 100 days or so.

The whole house... Thats the only thing left i need to sort out now.
