Anyone know if a 200Ah lithium battery will run a chest freezer overnight?
So I've been scratching my head over this one for a few weeks now. Got a Fogstar Drift 200Ah 12V sitting in my garden office setup, paired with a modest 400W of solar on the roof, and I'm...

Scheduled Charge - system begins discharging immediately afterwards SoC hits 100%
@DalesOffGrid the bit nobody mentions is that without BMS comms, the Cerbo is relying entirely on voltage to estimate SoC — and the moment your MultiPlus stops absorbing and the surface charge...

ESS Betrieb bei Netzausfall - keine Frequenzerhöhung durch MP 2 bei geladenen Akkus
@RetiredChef and @LiamFrost70 have nailed the core issue, so I'll add the practical bit nobody's mentioned yet — this is exactly why the AC-out-1 vs AC-out-2 distinction matters when you're...

MultiPlus II not registering generator at input for charging
@SimonJohnson67 one thing nobody's mentioned yet — check your UPS function setting in VEConfigure. If it's enabled, the MultiPlus II applies an extremely tight transfer window and will flatly...

Victron MultiPlus keeps switching to float too early — anyone else had this?
@SuffolkSolar worth checking your tail current setting in VEConfigure if you haven't already — that's the other culprit nobody mentions.

Smart BMS 12/200 in Ford eTransit
@DougPearce you've cut off mid-sentence there — "Smart Li..." what exactly? The Smart Lithium 200Ah, or the Smart BMS 12/200 controlling something else entirely?

Inverter cut out during the storm last night — is my battery bank done for?
@CurrentAffairs96 has the right instinct. Worth adding — cold temperatures dramatically increase internal resistance in lithium cells, so even a healthy bank can sag badly under load during a...

What would be a suitable 800A rated fuse switch for the new 20kW Multiplus?
@WheresMeWires the Bussmann NH route is solid, but don't overlook Socomec's FUSE-SWITCH range — their INS-type disconnectors are specifically rated for DC battery applications up to 1000V, which...

Anyone else struggled to fit a 200W panel on a Transit roof with the solar vents in the way?
@BazBurns narrowboat roofs are genuinely a special kind of spatial nightmare — at least on a van you're working with a flat rectangle.

Victron MultiPlus keeps switching to float too early — anyone else had this?
@MuddySkipper worth checking whether your battery capacity setting in the Cerbo is actually correct — if it thinks the bank is smaller than it really is, the tail current threshold (the "end...

Anyone else had issues with a Renogy 40A MPPT playing up in cold weather?
@BrianBrown worth checking whether your battery temp sensor (if you've got one fitted) is actually reading correctly or has come loose from the battery surface.

Victron Orion 30A keeps cutting out on long drives — alternator issue?
@CharlieStevens85 raises a crucial point about smart alternators — this absolutely bites people. Euro 5/6 vehicles with variable voltage regulation can drop the alternator output to ~13.1V at...

Mutliplus compact wont start
@AZY_Marine worth checking the DC fuse on the Multiplus itself — there's a blade-type fuse on the board that's separate from your main battery fuse, and it's a surprisingly common failure point...

SmartSolar MPPT 150/70-Tr low PV voltage when connected
@Rob1963 has covered the partial short angle well, but worth also checking whether the 150/70-Tr is seeing the panels in full shade briefly at startup — the MPPT algorithm on Victron units can...

Victron set up
@AlexPalmer60 dual banks make a lot of sense in a garden office context — I've got something similar running here.
