Sadly unlikely to be possible in my lifetime. With the short winter days at our latitude and the sun only reaching 16 degrees above the horizon in mid-winter I calculated I'd need another 55 panels and another 30kWh of battery storage to get us through the darkest / rainiest week in December...

... wish I'd thought of that ;) Oh no.. just spotted your new signature. I'd assumed the new MG was for the missus, not replacing the XPower. Have you broke the news to @salty? YW. Fingers crossed it is repairable - IME they usually are unless the puncture is too close to the sidewall 🤞

That's a huge difference. The cynic in me, wonders if demo vehicles have some software tweaks so that the consumption figure appears higher than it should?.... says the VW-driving gal! ;)

Hope you get over your cold soon, @Archev 😷

My understanding, which is from LiFePO4-based home energy storage balancing (so may be different with EVs) is that balancing is based on cell voltages, but with LFP can only commence when the cells are above a certain threshold (typically about 3400mV) as below that voltage is not a good...

Tyre repair fluid is temporary. As it is holding some pressure then, IMHO, would be better to take it to a tyre centre for a repair. I've heard rumours that using the repair fluid can stop some places from repairing punctures - maybe others on here know whether that's true or not?

The BMS will use coulomb counting, rather than voltage for SOC calculation. Because the upper knee on LFP cells is so steep the delta will be quite large (i.e. compared to NMC cells) when cell voltages are over 3.45V per cell, despite them being relatively well balanced. Graph below is no-load...

For NMC yes, but with LiFePO4 cells you'll often see bigger differences at the upper knee of the SOC-voltage curve.

Really? Shell V-Power Diesel is available throughout Germany 🤷‍♀️ https://find.shell.com/de/fuel/10026575-berlin-paulstrasse-20 Shell V-Power Diesel €2.469/L But, yes. it is a ripoff!

So for Jan and Feb, about 50kWh / day peak kWh. Is that your usage (i.e. including solar production) or energy import? P.S. have PM'd you.

I guess you have done the calculations - but I would have thought that - if your usage is that high for freezers and heat lamps etc. - then buying kWh at 5p, rather that 25p would result in massive savings, especially over the winter. What is your typical daily energy usage over 24h in winter?

Should have gone to spec-savers, my "reading-between-the-lines" was way out !!!

Yes :) Assuming you are referring to needing a two-core cable to connect a current clamp (as opposed to a data link for a remote energy meter)... the best choice would be to use twin screened microphone cable. This will have the necessary shielding to protect from interference as well as...

I thought that a lot of supermarket ones were shut down because a) many supermarkets don't own or operate the car-parks and b) there were issues as to who was responsible for waste water discharge on those sites. Being paid cash-in-hand, not declaring it for income tax and/or NI is, in my mind...
