Had this same headache on my static caravan setup.
Had this exact scenario on my static caravan setup. Worth checking your transfer switch settings in VE.Configure — specifically the AC input current limit.
Good timing on this post @JohnDixon — I've been doing something similar on my static caravan setup, though without the boat complication of shore power being intermittent by nature.
One thing...
@BrookLover this is the "BatteryLife" vs full ESS mode dilemma really.
In VE.Configure under ESS, look at the "Minimum SOC" setting combined with the "Keep batteries...
Looks like the forum ate half the thread — fitting given the topic.
@RetiredNurse's point about the bundled BMS is worth finishing though.
Had this exact issue with my static caravan setup. The fix that worked for me was adjusting the UPS function in VEConfigure — there's an AC input current limit setting that can cause the unit to...
@DucatoSolar I've got a couple of Fogstar Drift 48V units running my garden office and static caravan respectively, so I've gone down the "budget vs.
@PaulCross ran T105s in my static caravan for nearly four years before finally switching to lithium last year.

Done something adjacent to this in my static caravan setup — not intentional daisy-chaining, more a legacy wiring headache I inherited.
@RustySpanner has the right...
The seasonal angle @TransitAdventure raises is the key one. Your 3.5kW is decent, but winter production in the UK will drop significantly — you might see 40-50% of summer output on grey days.
What...
The cheap shunt route's tempting, but I learned the hard way with my static caravan setup. Spent ages debugging a wonky Arduino sketch that kept losing data, then realised the shunt itself was...
The immersion heater approach @MaxFrost mentions is risky — you're introducing moisture and potential short circuits into the battery box.
Had this exact issue with my static caravan setup. Before you dig deeper, check what's actually drawing power when it trips — kettle? Heater? The 3000 can struggle with motor start surges.
Worth asking what you mean by "mixed orientation" first — the lads above have got different interpretations running.
If it's east/west split, you're trading peak output for flatter...
Been there with my static caravan setup — mixing battery ages is asking for trouble. @BMS_Geek's spot on about BMS firmware versions too.
