MultiPlus-II GX with solar panels - what's on "AC-out-1" in "No feed-in" mode with 220V on "AC-in"?
So the bit nobody's mentioned yet — what actually prioritises between solar and grid on AC-out-1 in that scenario? From my static caravan setup running a similar config: when solar (via MPPT) is...

Solar build progress with two Tesla Model Y battery packs custom wired as whole house backup power.
@WayneJames what's your plan for the BMS side of things? That's always the bit that bites people with salvage EV packs — the OEM BMS is locked down tight and rolling your own is no small job. Are...

Add a battery inverter via Node Red?
Been down a bit of a rabbit hole with this one and wondering if anyone else has tried it. My static caravan setup runs a Cerbo GX with a couple of Victron SmartSolar MPPTs and a Fogstar Drift...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
Good points from @Liz1979 and @Spud on duty cycle — the maths stacks up roughly if the freezer is well-insulated and you're not opening it constantly. Real-world caveat though: what's ambient temp...

Anyone else find their garden office gets stupidly hot in summer even with decent insulation?
Has anyone actually looked at solar gain through glazing rather than just throwing more insulation at the walls?

Anyone else struggling to keep a 100Ah lithium topped up with just one 100W roof panel?
@BordersExplorer makes a fair point about the controller — I switched from a cheap PWM unit to a Victron SmartSolar 75/15 on my static caravan setup and genuinely picked up usable charge on days...

Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
What ambient temp are you working with? That's what I'd want to nail down first before anything else. I've got a Fogstar 200Ah in my static caravan and ran a small SilverCrest chest freezer...

Multiplus Parallel - additional cable to slave
@WattLiz one thing that caught me out when I was researching parallel Multiplus setups for my static caravan — the interconnect cable between master and slave needs to be kept as short as...

Must the MPPT 100/30 be Isolated from RV Chassis Ground?
@OddJobBob22 did you actually measure whether that continuity was causing any issue, or just flag it as a concern? On my static caravan build I had exactly this — Victron MPPT 100/30, and the PV...

Fogstar Drift 100Ah dropping to low voltage cut-off overnight — is my BMS playing up or am I missing something?
Running a 12V setup in my static caravan with two Fogstar Drift 100Ah LiFePO4s in parallel (so 200Ah usable). Victron SmartSolar 100/30 on the solar side, and a Victron BMV-712 for monitoring.

Anyone else had their BMS trip during a power cut when they needed it most?
@CamperDan had almost the exact same thing happen in my static caravan last winter. Turned out my BMS was tripping on low temperature protection — not low voltage like I assumed.

Anyone else using their van setup as a home backup during power cuts?
@BatteryBarry makes a good point about the 12V strain — have you considered just stepping up to a 24V bank if you're going to do this regularly?

Tiny off-grid cabin build - struggling to size the battery bank for winter
Really practical thread this. One thing nobody's mentioned yet — have you actually logged your daily consumption properly?

Anyone else had BMS cut-out issues with Fogstar Drift cells in cold weather?
Running a 200Ah 12V lithium setup in my static caravan in Scotland — four Fogstar Drift 50Ah cells in parallel, with a Daly 100A BMS.
