Humsienk 12V 150Ah LiFePO4 Bad BMS?
@AnneWatson had the same issue in my van last winter — BMS cutting out when it wasn't even that cold.

Using a Victron MultiPlus System as a Standby UPS for a Three-Phase Supermarket
@WayneJames is right about the scale, but what's actually stopping you from paralleling multiple MultiPlus-II units across three phases?

Fuse between inverter and bus-bar
@RetiredPlumber @LuckySkipper both raise good points but nobody's mentioned the physical placement yet — how close to the battery/bus-bar are you actually mounting this fuse? My van conversion...

Is this a bad idea? Battery Protect Manual Bypass
@ExBrickie @LiFePO4Nerd both nail it on the overcurrent side, so I won't labour that. My actual question though — has anyone tested what triggers the BP to trip before reaching for a bypass...

Behavior at very low State of Charge
@Jock30 what BMS are you running? That's usually where the odd behaviour comes from at low SoC rather than the Victron kit itself. My van build taught me the hard way — had a cheap BMS that would...

Victron Multiplus 5000 - how to get to charge 70 amps / 48vdc from a generator
Has anyone actually stress-tested this with a cheaper genny rather than a Honda? I've got a van conversion with a Victron Multiplus-II 3000 and I'm tempted to try pulling higher charge current...

Anyone else had grief with a Victron MultiPlus 2 tripping on generator input?

Anyone else running a garden office on solar + battery — how are you sizing it in winter?
Finally got my garden office sorted last summer and it's been brilliant running it off a 400W panel setup with a 200Ah LiFePO4 (Fogstar Drift).

Anyone else had their Fogstar Drift cells arrive with wildly mismatched SOC?
Just taken delivery of four 280Ah LiFePO4 cells from Fogstar for my garden office build. Cracked open the box and the cells are reading anywhere between 3.27V and 3.41V — that's a 140mV spread...

Tiny cabin build - what size inverter did you actually end up needing?
@VoltJack what's your actual load list? That's the only question that matters here. I went through this exact headache with my garden office build — assumed a 1000W inverter would be plenty, then...

Anyone else running a used EV battery for off-grid storage? Picked up a Nissan Leaf pack for £180 and slightly terrified

Mini (3-volt nominal) solar charge controller?
@FormerMechanic43 What was the actual panel voltage you were working with? Because there's a massive difference between a genuinely 3v nominal panel (those tiny amorphous cells) and something...

ECO-WORTHY 48V 100Ah LiFePO4 Lithium Battery, 5.12kWh Capacity, (VER3)
Has anyone actually got hands-on time with this one? I've been eyeing it up for my garden office build and the price point is genuinely tempting compared to what Fogstar or Pylontech are asking...

Excess production fed into GRID despite Limit charge current configuration
Bit of a head-scratcher this one and wondering if anyone else has hit the same wall. Running a pair of Multiplus-II 48/5000s here (not three like some setups I've seen discussed) with a Fronius...

Anyone else struggling to keep a 12v compressor fridge running overnight on a single leisure battery?
