Just to add to what @LB_Camper said — mine did a switchover so fast my laptop didn't even blink, though my cabin kettle somehow still managed to trip the shore power breaker on day one because I'd...

@Bazza makes a fair point but yeah, even accounting for PWM losses you'd still expect some consistency in the numbers. Had almost the exact same situation in my van conversion last year — swapped...

DodgyRigger | 847 posts @SaltyMechanic Yeah, your MultiPlus-II 48/5000 is only rated 4kVA continuous — a 7kW Type 2 is asking it to perform miracles mate.

Been there, @LesHarris. The rating on those cheap units is almost always a fantasy figure - measured under ideal lab conditions that bear no resemblance to real-world use.

Really interested to hear how you get on with the Fogstar long-term @SaltyMaker — they've got a decent reputation for the price point.

HamishLee | Posts: 312 Worth asking — did you have any load still drawing from the bank over winter?

Pretty sure this is a known quirk with the DCC40S specifically — I ran one for about eight months in my motorhome before switching over to a Victron Orion-Tr Smart. The DCC40S can behave strangely...

SaltyRigger | Posts: 23 @Charlie1981 Quick one — have you thought about where the BMS will sit in relation to your fuse placement?

@PennineBoater the OP got cut off so I'm guessing you're moored somewhere with tree cover or a bridge causing intermittent shading on one panel?

AngliaCruiser | 1,203 posts @DailyDream Honestly, once you've got the Orion-Tr Smart doing its job properly, the old split-charge relay is just redundant weight and potential confusion.

MountainGeoff | 847 posts | ⭐ Trusted Member @PanelMike congrats on the build! The honest answer is: 400W will be brilliant June through August, adequate in spring/autumn, but genuinely struggling...

@SilverRanger nice write-up, curious what you ended up with for storage? Running a similar setup at my cabin and the battery choice was honestly the biggest headache.

@BirchLover that PowerAssist revelation is real — I went through exactly the same moment on my static when I first plugged in the kettle and the microwave at the same time without tripping...

NotAnElectrician48 | 156 posts | 🏠 Semi Off-Grid House @CraigLamb something nobody's mentioned yet - with paralleled AGMs you really want a dedicated battery monitor with a shunt, like a Victron...

Reply by NigeScott98: @Ben1968 Good shout on upgrading from that ancient leisure battery - thing's probably got the capacity of a AA at this point!

My Victron Orion-Tr Smart did the exact same sulky act on a hot July run down the M6 — turns out the Transit's alternator was already sweating like a nurse on a 12-hour shift before the B2B even...

@SparkyHiker is absolutely right — Equalisation is completely the wrong tool here. @LeeParker that could actually damage LiFePO4 cells if anyone's running lithium, so worth correcting firmly. The...

@LuckySkipper is probably right about the default profile being the culprit. I had something similar on my cabin setup with a Renogy 20A and generic LiFePO4s — absorption was cutting out way too...
