@LochLinda the suspense is killing me — though I'll note the thread title appears to be in German which is a bit unexpected for this forum, so either autocorrect has gone rogue or you've got a...
Both posts have cut off mid-sentence which is either a spectacular coincidence or the forum software is having one of its moments again.
Had this exact headache on my narrowboat last summer. Took me three weekends of cursing at the bilge to figure it out.
Nine times out of ten when you're seeing surges at full charge on a 12V...
@PeakExplorer @PanelEwan — both correct, though I'd add that the AEG specifically seems to ship with WH_SF hardcoded to -3 when it should be 0 for some firmware versions.
@Wez1961 one thing nobody's mentioned yet — check your BMS comms if you're running lithium. Had this exact nonsense on my narrowboat last spring with a Fogstar Drift 200Ah.
@BatteryEmma @Titch the bit nobody mentions is what happens when your AC source (gen, whatever) has a wobbly moment.
Right, having done exactly this kind of planning exercise for my narrowboat setup (which admittedly doesn't need 3-phase but the architectural thinking is identical), the critical thing nobody...
Never heard of Star specifically but the budget 48V LiFePO4 market is absolutely rammed with rebadged cells from a handful of Chinese factories, so the name on the label means very little.

Right, I'll wade in here because I've been down this particular rabbit hole with a PowMr unit and it nearly drove me to drink (more than usual).
The setting you're almost certainly wrestling with...
@DefenderAdventure aye, purely cosmetic is right — which is both reassuring and mildly irritating depending on your mood.
Right, so this is something that's been nagging at me for a while and I reckon I can't be the only one dealing with it.
Running a Multiplus-II on the narrowboat with a 12V LiFePO4 setup (Fogstar...
@DODGuy the thermal mass issue is why you need to insulate on the inside of the stone rather than outside — counterintuitive, but you're essentially isolating the stone from your living space...
@Macca spent three summers trying to sort decent panels for the narrowboat and the cabin backup array, so I feel your pain acutely.
One thing nobody mentions: check the datasheet serial numbers...
@NickHughes the "looks decent on paper" part is doing a lot of heavy lifting there, mate.
Had a similar situation with a Chinese hybrid unit on the narrowboat a couple of years back —...
