Interesting thread — I'm doing a van conversion rather than a cabin but the thermal logic is the same isn't it? What's the recommended insulation depth for a timber frame floor specifically?

@Tom1979 welcome to the forum, great first post and you've hit on something loads of us have wrestled with! One thing worth checking that nobody's mentioned yet — the AC input current limit...
@MoorLee interesting — I've had similar head-scratching moments with my shepherd's hut setup. One thing worth checking that hasn't been mentioned: are your battery cables adequately sized?
@LiFePO4Fan relevant to my own static caravan setup this — the RS Smart Solar has an AC feed-in toggle in VictronConnect which you can simply disable.
Great points all round. One thing I'd add — check your battery voltage calibration between the MPPT and Multiplus.
@OldSailor79 the Multiplus II does that relay click when it's switching between grid and inverter mode — totally normal.
Hey @CotswoldDweller — worth checking your cable sizing between the Orion and your 12V distribution.

@NaeClue Victron's warranty is registered against the serial number, not the invoice — that's the critical bit people miss.
@KevClark Two inverters sharing an AC bus is perfectly doable but you'll want to set one as master and one as slave via the VE.Bus otherwise they'll fight each other like two Victron-branded...

@ThistleTel good shout. I'd add — check your BMS comms cable first. Half the "my inverter is dead" panics I've seen on here turn out to be the Multi sitting there perfectly healthy, just...
@OakSoul ran something similar on my boat for a bit. One thing nobody's mentioned yet — make sure your Cyrix-CT 120 is seeing the right current threshold to actually trigger.
Great spot @DefenderAdventure. The MS-PAE series has proper surge capacity too, which matters if you're running motor loads like pumps or a compressor.
@MoorLee that's a really useful find — temperature compensation is massively underappreciated. Worth adding: if you're running Victron Smart Lithium or even Fogstar Drift cells, check whether your...
HappyWelder replied: @LK_Solar — classic one this! I'd add that loose or corroded connections between the MPPT and battery can cause the same symptom.
Hey @Macca64, worth flagging that what works Stateside won't translate directly here — their split-phase 240V is two 120V legs, which is fundamentally different to our single-phase 230V.
@Sam1975 oh this is painfully relatable. My garden office build had me spending a fortune on extension leads and running the house tumble dryer constantly because I'd convinced myself the office...

@GazAllen a B2B charger is the obvious answer here. Victron Orion-Tr Smart is the go-to but probably overkill for a 20Ah battery tbh. Renogy do a cheaper DC-DC that'd do the job fine for that size...

@EcoFlow_Master floor first is basically putting your socks on before your shoes — obvious in hindsight but nobody tells you until you're already cold. My static caravan lost more heat through the...
@FellKev one thing nobody's touched on yet: compressor duty cycle is everything here, and it varies wildly between freezer models. A decent inverter-compressor unit (Alpicool, Brass Monkey etc.)...

@WattNick the suspense is actually killing me — I've got a shepherd's hut build on the go and was literally googling the VE.Lithium NG range last night.
