We do have a holiday let too which is all electric attached to same supply but the total never goes below 900W. Will be using a plug in meter over the next few weeks to see what’s using it. 900W x 24 x 30 = 649kWh At 29p/kWh that’s £188 per month just for base load. I dread to think what my base load is, as it’s a busy home with 2 adults + 4 kids ( 11-17 ) with all kinds of tech left plugged in / chargers on / vampire loads-a-plenty. @SteamyTea, please don’t work it out, or I’ll have to start removing sharp objects from my home. I’ve got about 8kWp of PV going in soon, plus a 9.6kWh battery system ( surplus stock from a non paying client which has only cost me a couple of £k ), so hopefully I can stave off the rising electricity bills soon! They’re the older 2000’s ( Pylontech ) batteries, does anyone know if mixing those with a couple of the newer 3000’s will cause any issue? Hoping to add 2 more cells as I think I will charge these without issue. Iirc if you parallel rechargeable batteries of differing capacities, they try to achieve “equilibrium “. @Onoff? Will be adding more PV later in the year to connect to my home-brew ‘thermal battery’. Will add some statistical data when the system is live.

For every kWh the kids can save, give them 20p. Will work out cheaper than a PV/battery combo.

I'll get back to you on the results of that experiment Don'y hold your breath. My PV costs will be an "at cost minus favours to date" sort of thing, so my payback will be 5-6 years max, probably less.

We seem to be falling into a trap that sudden and extreme rises are the new normal. Heard the same in '73. I think some caution about going over the top to generate power may be a false economy. Though cutting back waste is always a good thing. I could almost halve my 'per person' usage if I doubled he occupancy of my house.

Benjseb Posted April 3, 2022 Share Posted April 3, 2022 One of our issues is the holiday let/AirBnB attached to the house. Im thinking of adding some “Think of the planet, please use appliances when sunny” signs but they will probably be ignored. Or people will see straight through them and realise im just trying to save money 😂 We can’t currently get a smart off peak tariff as our smart meter installer was scared away by a loose screw on the fuse cover. DNO confirmed no risk at all. So another appointment booked for a less fussy installer. Let’s hope! Link to comment Share on other sites More sharing options...

SteamyTea Posted April 4, 2022 Share Posted April 4, 2022 1 minute ago, ProDave said: I don't see that, It was stable, and with the USA imposing energy conservation rules, it stayed stable until the Iran-Iraq war after the Shar of Persia was disposed. The 80's, especially in the UK, was caused by North Sea Oil comping on stream, and the Saudis pumping more to stop the USA investing. My Mother always tells the story about when she was in the Far East and the oil price dropped to $10/b from $15/b, and how all the oil workers where convinced that the industry was dead. Too much knee jerk reaction to energy prices. Just been a bit on the radio about milk prices. Farmers thought there industry was over when diesel hit 20p/litre. Europe has plenty of regassification capacity for LNG, the bottle neck is the ships, but they are relatively quick to make/convert as it is mature technology now. This coming winter may be a bit expensive, but not as expensive for the Russians, they will run out of cash and will not be able to resupply their front line forces. Going to be an interesting year, especially for economists. Link to comment Share on other sites More sharing options...

My understanding is it's reasonably OK to do this as long as the battery types are the same e.g. both lead acid but never say lipo + lead acid. Where issues can occur I think is if the lower capacity one over discharges but you don't realise as the bigger ones are "taking up the slack".

In round figures at the moment oil is about 10p per kWh which means a SCOP of more than 3 for ASHP or new condensing oil boiler which should be much better than the Aga.

Iirc if you parallel rechargeable batteries of differing capacities, they try to achieve “equilibrium “. @Onoff? While connected in parallel the terminal voltages are obviously identical so it's impossible for one battery to be over or undercharged. Current will just share out safely between them. However, I would make sure both batteries had the same terminal voltage before joining them as the above only applies when the voltages are exactly the same.
