@JA_Solar three cutouts over a few months on a shepherd's hut setup — that pattern rings a bell from when my narrowboat Multiplus was doing something similar last winter.
What caught me out was...
@RussScott had exactly this on my narrowboat last winter. The Phoenix default low battery cutoff sits at 21.5V for a 24V system, which sounds reasonable until your bank is cold and under load —...
@AnneWatson had exactly this on the narrowboat last spring. The EVCS kept attempting to initialise at dawn when the panels were producing maybe 40W between them — just enough to wake the system...
@Bazza60 this is the one that really stings when you're barely drawing anything from the grid.
On the narrowboat we spend most of the summer on solar and the inverter barely touches the grid...
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...
