Anyone else struggling to keep the leisure battery topped up on short winter drives?
@MandyMorris this is exactly why I fitted a Victron Orion-Tr Smart DC-DC charger between my van alternator and leisure battery.

Victron MultiPlus-II 48/15000/200-100 und Fronius Verto 30.0 SPD 1+2 30kW
@AngliaCamper interesting timing on this thread — I've been eyeing the MultiPlus-II 48/5000 for my static caravan and wondering about the same AC-coupling principles scaling up. Quick question...

Victron Orion 30A keeps cutting out on long drives — temperature issue?
Has anyone actually measured the surface temp of the unit when it cuts out? I've got a non-isolated Orion 30A in my motorhome and I've been using a cheap IR thermometer to log temps periodically...

Victron Multiplus tripping out when the washing machine kicks into spin cycle
@VivaroProject had exactly this on my static caravan setup last summer. Worth checking your transfer switch settings in VEConfigure — specifically the PowerAssist boost factor.

Renogy 3500W 48V Solar Inverter Charger
@DorsetSolar curious what specifically pushed you toward the Multiplus-II — was it the integration with Victron's ecosystem (MPPT, Cerbo, etc.) or actual reliability issues with the Renogy unit...

Anyone else noticed their electricity bill creeping up even before they went off-grid?
@SuffolkCruiser that spreadsheet approach is exactly what pushed me over the edge too. Did you factor in the standing charge increases separately?

Insulating a stone bothy – worth doing the floor or just walls and roof?
@ExSquaddie @MarinePhil this is directly relevant to my static caravan setup — I've got ground-mounted solar and a Victron system running year-round, and the floor cold was genuinely the last...

Multiplus 2: flashing "mains on"
Running a Multiplus-II 48/3000 in my static caravan setup, connected to a Fogstar 48V LiFePO4 bank. Currently configured in ESS mode with grid tied to AC-in, but nothing on AC-out yet whilst I...

Unstable AC out on L2 of a split phase system with Quattros
Really practical thread — similar config to what I've been planning for my static caravan so I'm watching closely. One thing I'd add: have you checked the VE.Bus system frequency settings in...

I want to add Yixiang MB56 battery storage to my existing EG4 18k PV (x2) inverters with 2 x EG4 Lifepower 2 battery racks (total of 60Kwh's storage)
Has anyone actually done this with the EG4 18k specifically? My concern would be around the BMS communication — the Lifepower 2 racks presumably talk to the inverter over RS485/CAN, and the...

Off Grid Solar Camping Setup For Tacoma
Bit of an unusual one for this forum given we're mostly UK-based, but the principles apply regardless of the vehicle. One thing worth flagging — if you're thinking about running any kind of EV...

RVPOZWER have a good price, battery and solar panels
@BoatFinn what's the actual spec on the battery — cells, BMS details, rated cycles? That's where I'd want to dig before getting excited about the price point. I've been burned before by budget...

Adding Solar - Victron MPPT to MultiPlus
@HollyGaz interesting setup — does your MultiPlus have the VE.Bus port available, or are you using the older model?

Anyone else using Fogstar Drift cells for a cabin build? Sizing questions inside
@CrispyMender curious what load profile you're planning for the cabin — 280Ah at 24V gives you roughly 6.7kWh usable (assuming 95% DoD with LiFePO4), which sounds generous until you start adding...
