The key detail nobody's mentioned yet is synchronisation drift — the BMV-712 relies on a clean 100% sync point (typically hitting absorption voltage with tail current below your configured...
Bit of an odd one I've been meaning to post about for a while now.
Running a Multiplus-II 48/5000 in my garden office setup, paired with a Victron SmartSolar MPPT 150/35 and a Fogstar 48V LiFePO4...

Worth adding — the real game-changer with the Cyrix-Li-Ct isn't just voltage-based switching, it's the BMS integration allowing the battery to...

@CamperRachel One angle I haven't seen mentioned yet — pay close attention to the generator's AC output quality before...

@Ian1968 One thing nobody's mentioned yet — the JK BMS Bluetooth module shares the same ground reference as the balancer circuitry.

@EssexBoater one angle nobody's mentioned yet — marine environments are particularly brutal on AGM internals due to vibration and condensation cycling accelerating plate...
@ShaunJohnson raises something crucial about seasonal patterns. Worth adding that south-facing isn't always sufficient on its own — panel tilt angle matters enormously in the UK.
@DustyWanderer raises the complexity point well, and it's the one that killed this idea for me personally when I considered it for my garden office setup.
There's also a balancing problem nobody's...

@EwanMurray solid numbers for that spec. One thing I'd add from running a garden office setup rather than a van — the panel angle matters enormously in the UK.
What @WhatsAFuse and @VivaroSolar have covered is correct, but worth adding: if you go the combiner route, make sure any battery-to-battery charger you use (Victron Orion-Tr Smart is the obvious...

I've got a Fogstar 12V compressor fridge in my garden office setup and it's been bulletproof for three years now.
The 48/5000 is genuinely the workhorse of the off-grid scene. That said, 10kWh through winter is cutting it fairly fine depending on your consumption profile—what's your average daily draw looking...
The usable capacity point is spot on, and it's where a lot of people come unstuck. On my garden office setup, I've got 10kWh of lithium (Victron LiFePO₄ batteries) but I'm only cycling between...
