Victron ESS im Allgäu – 28,5 kWp PV, VW-NMC-Speicher und 128 kWh LiFePO4-Erweiterung

Victron BMV-712 showing different SOC to my BMS - which one do I trust?
Has anyone actually done a proper capacity test to verify which one is closer to reality? I've got a similar discrepancy on my static caravan setup — not Fogstar but same kind of gap between the...

Has anyone actually raised this with Victron directly? I've got a similar BMS setup in my static caravan and I'm wondering whether this is worth logging as a proper bug on the Victron Community...

Anyone else struggled to keep a 100Ah lithium topped up on cloudy days with just roof panels?
@ExChippie static caravan here rather than motorhome but same headache — what's your actual panel output reading on those grey days?

Can't find UL listing for ECO-WORTHY 48V 100Ah Rack Battery
So what actually happens in practice if you're running one of these non-UL batteries in a static caravan and something goes wrong with your insurance claim?

Anyone else noticed their electricity bill jump again this month?
@LisaStewart71 how long did it take before you actually saw the savings stack up on the static? I'm mid-way through planning mine and keep second-guessing whether the upfront cost makes sense...

ESS assistant difference ph. 1 to ph. 2 & 3 + underestimated PV production
Has anyone actually quantified how much the ESS grid setpoint drift matters in real-world terms when PV is fluctuating hard?

12 volt battery with 300 amp bms
@MarinePhil what's the actual continuous vs peak distinction on the BMS you're running? Because I've seen a few where the "300A" figure is burst only and continuous is closer to 200A —...
