Victron BMV-712 showing different SOC to my BMS — which one do I trust?
Good points already made on tail current and coulomb counting. One thing worth adding — the BMV-712 will drift over time if your shunt isn't the only path for current.

Charging Station NS won't connect to car
Been having a similar head-scratcher with my static caravan setup and thought this thread might be relevant to a few of us running EV charging off-grid. I've got a Victron MultiPlus-II 48/5000...

Controller showing absorb all the time
Seeing this crop up a fair bit lately and had something similar on my static van setup last summer, so thought it worth sharing what I found. Running a Victron SmartSolar 100/30 with a 200Ah...

Anyone else noticed their electricity bill has gone up even though they're barely on the grid anymore?
Same experience here with my static. Even though I pull maybe 2-3 units a month from the grid now (just running the immersion occasionally as backup), the standing charge alone is eye-watering.

Orion -Tr Smart 12 I 12-18 isoliert zur Erhaltungsladung der Starterbatterie
@TransitAdventure — worth noting that the Orion-TR Smart isolated variant behaves quite differently from the non-isolated when used purely for starter battery maintenance.

Humsienk 300Ah 200A Smart LifePO4 Battery, Seplos 200A 10E Bluetooth BMS with LCD Screen, Balance Boards, and Front Cover Plate - Colorado
Interesting build — I've been keeping an eye on the Seplos BMS units for a while now. The 10E series with Bluetooth is genuinely decent kit for the price, and having the LCD screen on the front...

3Ph 90kVA System not accepting Generator
Curious whether anyone's tackled a large 3-phase Quattro setup refusing to accept a generator feed — I've been wrestling with a related (albeit smaller-scale) issue on my static caravan site and...

Swapped to lithium on my narrowboat – shore power charger now playing up
@GrumpySparky the absorption voltage ceiling is the killer with those old units — most are capped at 14.4V which sounds fine on paper but they'll sit there for hours trying to "top off"...

Signature Solar EG4-LL 400ah (12V) Server Rack Battery Issue???
@KevClark is right — EG4 is very much a North American brand, you'll not find them stocked anywhere mainstream over here. That said, BMS cut-out behaviour is fairly universal regardless of...

Before ordering cables & fuses: final technical review of 24V Victron campervan schematic
@QJ_Builds curious what your mistakes were — I'll share mine whilst waiting. On my static caravan 24V setup, the two things that nearly bit me were: Cable sizing at the inverter — people...

Anyone else had issues balancing a secondhand LiFePO4 pack after sitting idle?
@Gibbo39 worth connecting each cell individually to a bench power supply and logging the resting voltage after a 24-hour soak — not immediately after charging.

Victron MultiPlus-II 48v — anyone running one in a static van on a tight 13A supply?
Finally pulled the trigger on a MultiPlus-II 48/3000/35 after months of deliberating. Running it in my static caravan alongside a 48v Fogstar Drift 200Ah LiFePO4 battery bank and about 1.2kW of...

Has anyone managed to monitor battery SOC AND grid import together on one dashboard?
@TelHall this is exactly my setup — Multiplus II, Fogstar Drift 10kWh, Cerbo GX in my static. The piece that tied it all together for me was the Victron Modbus TCP integration in Home Assistant...

Victron MPPT keeping my batteries at 80% even with float set to 14.4v — anyone else had this?
@TorDweller raises something worth expanding on — if you've got BMS communication set up via the Victron VE.Direct or CAN bus interface, the BMS itself can be actively instructing the MPPT to hold...
