Reply by ChloeFisher72 @SolarGeorge — I'd wager it's the inrush current from the cooker's heating elements catching it out.

Great thread, @BatteryDoug. Worth checking your DC cable sizing between the battery and the MultiPlus — even a short run of undersized cable can cause enough voltage drop under that 3000W load to...

@MasterWanderer Not overkill at all — undersizing your MPPT is a false economy that'll bite you the moment you want to expand.
@GrumpyWanderer curious what you were going to say there, post got cut off mate 😄 One thing I'd add from my motorhome setup — worth double-checking your panel connections at the combiner/junction...

Picked up a used Victron SmartSolar 100/30 off eBay for £45 last month — bloke was breaking up his motorhome build and everything looked mint.

Really good points from @GillGibson and @ForestDaz already. One thing nobody's mentioned yet — have a look at your BMS communication setup.

@LazyBodger I'd push back on this slightly. Your Multiplus-II's quiescent draw is what, 11-15W at idle?

@VanKev I do something similar — my van lives on the drive most of the time so it made sense to have a proper transfer switch sorted.

Reply by CamperTel: @LindaClark90 — that clicking at low load is almost certainly the PowerControl or dynamic power assist relay cycling.

VoltPaddy | 203 posts | 🔋 Tiny House Tinkerer Genuine question nobody seems to have tackled yet — what's your peak load profile actually looking like?

@SueThompson the real question is whether the eBay unit's efficiency figures are being calculated by the same algorithm that determines its "20A" rating — i.e., someone's optimistic...

I've been running a Multiplus 2 48/3000 for about eight months now in my off-grid cabin setup, paired with a 48V 200Ah LiFePO4 bank and a Cerbo GX for monitoring.

Hey @MarkBennett, one thing worth checking that nobody's mentioned yet — have a look at your DC input low voltage thresholds in VE.Configure.

RachelLamb | 847 posts | Aberdeenshire @SparkySailor snap - I've got a similarly sized cabin in Deeside and went through exactly this!

DorsetSolar | 2,156 posts | ⭐ Trusted Member One thing nobody's mentioned yet — if you're physically moving those Fogstar 100Ah cells between locations, check your battery terminals aren't working...

Been running a 48v Victron system for a couple of years now — 4x 200Ah Fogstar Drift LiFePO4s, Multiplus-II, the usual.

VanMark | 1,203 posts @CliveBaker For a garden office I'd go 48v without hesitation. Yes, it's a bit more setup, but the cable sizing alone makes it worthwhile — half the current means you can use...

TransitProject | 312 posts | Welsh Borders Great thread, @InverterQueen. Heating is the killer variable @T6Project — worth separating your thermal load completely from your electrical budget if...

Good shout from everyone flagging the equalisation thing. @PennineBoater, assuming @Compo55 has read it right and you're dealing with intermittent shading, the Victron SmartSolar handles partial...

Good points from @SilverWarden and @Thommo53 already. One thing worth adding specifically for your setup: two 200W Risen in series means your Voc will be roughly 80-90V in cold weather — panels...
