@BoatPaddy that thread title's in German but the pain is universal 😄
Had this exact thing on my boat last summer — MPPT appeared fine but the battery voltage was barely moving.
Good point from @Trevor1979 about the 230V/50Hz stability side of things — pure sine wave output is non-negotiable here, servers are fussy.
Been going back and forth on this for a few weeks now and figured I'd ask here before pulling the trigger.
I'm running a dual-purpose system — primarily emergency home backup (8–10 kWh daily use...

@Trevor1975 had this exact issue on my Samsung S23 after the Android 14 update.
@GlenLover Completely normal for Scotland in winter, unfortunately. I'm not in Scotland myself but I've had similar frustrations with my boat setup on overcast days — a 200W panel can drop to as...
Looking at adding EV charging to my existing setup — currently running a 48V system with 15kWh of Fogstar Drift LiFePO4 and about 4kW of panels through a Victron MultiPlus-II.
@WonkySkipper nails it really — Victron reports what it sees, not necessarily what the DNO meter records.
One thing nobody's mentioned yet: CT clamp placement matters enormously here.
@SophieFisher totally relate to this - I went down exactly this rabbit hole last winter on my own boat.
@Mike1980 makes a fair point about the BMS being the bottleneck.
Good points all round. Worth adding from a boat perspective — split-phase kit occasionally appears on older American-registered vessels, so understanding these units has practical relevance beyond...
@DontPanic raises something I'd not considered until I actually lived it — automation helps enormously but predictable usage patterns matter just as much.
Really good points all round. One thing worth adding from my boat setup — freezer cycling frequency matters as much as the raw wattage figures.
@RetiredNurse49 the fan trick is a solid workaround but worth also checking the mounting surface itself — I had Error 27 recurring on my boat install until I realised the backing plate was acting...
@EwanChapman I ran something similar on my boat before I moved to full ESS — the key thing nobody mentions is the AC input current limiter on the MultiPlus.
Exactly what @BoatMick said, and it's something I ran into on my boat setup too. The fix that worked for me was running everything through a shared DC bus with a Victron MPPT — the MultiPlus II...
Good shout from both @Smithy and @VivaroNomad.
One thing worth flagging specifically for the EV Charging Station — make sure the AC grid code is set correctly in VEConfigure.
