Interesting topic this one. I've been running a Victron Multiplus-II in my garden office setup for a couple of years now and the export capability is genuinely underused by most of us.
The real...
@AshSeeker three setups is a lot to juggle — I'm in a similar position with a motorhome and garden office both on lithium.
The bit most people miss: daily cycling calls for lower charge ceilings,...
@TerryScott72 makes a fair point about the usual suspects, but with that specific combo I'd look hard at the BMS communication first.
@WattAMess25 200W is borderline at best in winter, honestly. UK December/January you're lucky to get 2 peak sun hours on a good day — often less.
@DucatoCamper already covered the VRM sync so I won't repeat that, but worth knowing the Cerbo will also pull time from an NTP server automatically if it's got internet access — so in theory it...

@Gazza82 one thing nobody's mentioned yet — with LiFePO4 on a boat you really want a proper battery monitor, not just relying on voltage.
@Nobby30 the bit that trips most people up is the voltage side of things too — cold panels actually push higher Voc, so if you're running two 200W panels in series check your array doesn't spike...
@GoldenMaker the V2G angle is where this gets interesting long-term, but practically right now your Leaf isn't going to talk back to a non-CCS setup without serious faff.

@CamperDan what was the load at the time of shutdown? Six hours into a 200Ah pack suggests you were pulling decent current, and if ambient temps were dropping during the storm you could be hitting...
@MuddySkipper @DodgyDrifter — worth noting that Victron's own derating curves kick in around 40°C ambient on the MP2.
Been running a 24V system in my garden office for about eight months — two Fogstar Drift 200Ah cells in series with a Daly Smart 24V 100A BMS, charged via a Victron SmartSolar 100/30 and a Victron...

Worth adding — if you haven't already, dig into the input voltage lockout settings in VictronConnect.
@StuCampbell yeah the rebound effect is real but I'd add a slightly different angle — when you see your generation numbers on the Victron app you start to feel almost rich with energy.
@Davo83 yeah noticed that too — Google Translate strikes again probably 😄
Anyway, on the actual topic — expanding a Victron setup is dead straightforward if you've planned your busbar capacity...
Three-phase is brilliant for that scale, but I'd push back slightly on the redundancy angle. You're actually more dependent on a stable three-phase supply than you might think—if one phase goes...
