Re: PAS 63100:2024 - Protection against fire of battery energy storage systems for use in dwellings

Don't be bringing science into our accounting work! [/quote] :lol: It's quite a big deal though, isn't it? This makes it quite a lot harder and more expensive to install home batteries. Will also worsen the perception of them, making people think they're more dangerous than they actually are, which...

This would be frustrating. My understanding is that there have been almost no fires due to LFP batteries. Does this feel like inappropriate standards for LFP batteries? Surely dodgy e-bike batteries more of a fire risk?

Re: Battery-inverter cables upgrade

I'm seeing a lot more battery packs and inverters in the 80-480V range. If you're charging/discharging much faster than 100A then this seems very sensible. Ooh where have you seen those? I'd like the 45kWh battery system I'm dreaming of installing to have 15kW inverter. To keep current to 100A, tha...

Re: Idiot's guide to a self build battery

Very true. I've just been I touch with him myself. I note my post has a wee warning sign beside it. I wonder if it automatically looks for bot or AI stuff? Clever feature if so.

Re: Idiot's guide to a self build battery

I used Chatgpt to summarise this thread, not having hundreds of hours to read in detail :D It seems to have done an OK job. I asked it to include suggested suppliers. What do you think? Can delete the post if not helpful. Building a DIY LiFePO₄ battery storage system requires careful planning, quali...

Re: New wind record?

I'm actually pretty disappointed that wind power will only average about 9.4GW this year, up from 8.8GW two years ago. That's fairly paltry growth, and surely wind power capacity has grown by a lot more than that. I assume curtailment has a lot to answer for. Luckily other trends have been positive,...

Re: New wind record?

Iamkate showed 22.1GW earlier today, which I think is 0.1GW higher than the figures I saw earlier.

Looks like wind averaged over 20GW in the last 24hrs. Surely a record. I'm more interested in day and month averages these days than the short term peak figures.
