Had this exact headache on the narrowboat when I first wired up ESS — kept seeing small grid draws even with the batteries sitting comfortably at 80%+.
Turned out my minimum SOC and grid setpoint...
@WattAMess25 — you've hit on something that caught me out badly during my first winter on the cut.
The Quattro's AC-in-2 is fundamentally a "generator input" in Victron's logic, even if...

Been running a mixed string on my narrowboat for about eighteen months — a 200W Renogy alongside a 150W panel I salvaged from the static when I upgraded it.
@WonkyWelder I ran mine on the narrowboat for two winters doing exactly this — mostly ticking over, occasionally earning its keep when the alternator or solar couldn't keep up.
What won me over...
@FrostyHiker done exactly this — ran a 200W panel on my 58ft boat for two seasons before I wised up.
The killer nobody mentions is tree shadow.
Finally pulling the trigger on getting the static wired up properly. It's been running on hook-up whenever we visit, but we're losing the EHU pitch next spring and I want it fully self-sufficient.
Been running a Pi on the narrowboat for about eighteen months now, pulling data from the Victron via VE.Direct cable — proper game changer compared to squinting at the SmartSolar display.
The bit...
@VoltFiona mate, I completely understand. Last winter on the narrowboat I had the Cerbo GX alerts set so tight I was practically living inside the VRM portal.
@OffGridHamish this is worth digging into the Victron docs properly rather than guessing. The MP 48/8000 datasheet specifies a DC input low shutdown of 44V by default, but — and this is the bit...
@BoatFinn from a practical standpoint on my narrowboat setup, the concern is more about string design discipline than paperwork.
Something I noticed on my narrowboat setup that nobody's mentioned yet — firmware consistency between the two units.
Had a similar overshoot issue after I updated one MultiPlus-II but forgot the...
Both worlds here — narrowboat and static caravan — so condensation has been my nemesis for years.
The thing nobody mentions alongside any forced-air heater is thermal bridging at your windows.
The usable capacity trap is real — I learned that one the hard way on the narrowboat. Bought what I thought was a 14kWh Lifepo4 bank, then realised I was only getting about 10kWh usable when I...
