@PennineSolar did this on the narrowboat a couple of years back. The Xantrex wasn't terrible but the lack of any decent monitoring drove me mad — you're essentially flying blind.
One thing worth...
@WingAndPrayer absolutely — and don't underestimate how temperature plays into this on a boat. Bilge temps on a narrowboat can drop below 0°C in winter, and most lithium BMS units will cut...
Had exactly this on my narrowboat setup last winter. MultiPlus-II 3000 was calling float at around 80% SOC according to my BMV-712 — drove me mad for weeks.
Turned out to be a combination of two...
@Deano interesting setup — AC-coupling a Growatt grid-tie with a MultiPlus-II is doable but the frequency-shift load shedding (Victron's standard method) needs careful attention with Growatt...
@DevonNomad interesting you mention the Fogstar pairing — I've been running a similar high-voltage setup on my narrowboat for about six months now and the silence is almost eerie after years of...
@JackeryGuy this crosses into territory I've spent a fair bit of time with, running a narrowboat setup where I occasionally need to feed shore-power circuits from battery.
One thing nobody's...
@TracyMitchell the low voltage warnings in cold weather are almost certainly your battery internal resistance increasing rather than the inverter itself.
@RetiredChef is on the right lines, but also worth checking whether your EVCS is actually on the same VE.Can network segment as the Cerbo.
Good point from @Paddy on the settings side of things. One thing I'd add that's bitten me before on my narrowboat array — double-check your cable sizing between the SolarSense 750 and the charge...
@CharlieStevens85 classic symptom of the tail current threshold being set too high relative to your battery capacity.
@Midge52 the HQ number question is a good one — on the Smart Lithiums it's embedded in the Bluetooth device name within VictronConnect, format is something like HQ2234XXXXX.
@DorsetCamper this one caught me out too on the boat. The ESS assistant won't show as active on the Cerbo until the VE.Bus firmware on the MultiPlus-II is at a compatible version with your...
@Bazza60 had the same saga on the boat — turns out the input voltage drop was compounding the thermal issue on mine.
@FormerCop nailed the realistic wattage — and that's before you factor in the MPPT not even bothering to wake up properly on deeply overcast mornings.
On my narrowboat I run 400W panels feeding a...
Re: Sterling B2B 60A vs Victron Orion 30A — worth paying double for the Victron on a leisure battery bank?
Worth flagging that the Orion Smart (not the non-Smart version) integrates with VRM and...
