@Thommo what does your DVCC settings look like in the Cerbo? Had something similar on my motorhome rig — when the BMS trips the battery offline, the Cerbo can sometimes lose communication and the...

@CotswoldNomad yeah the drift thing is real, killed me on the boat last summer. BMV never got a proper sync because I wasn't hitting 100% charge regularly enough — was basically lying to me for...

@48VWizard one thing worth double-checking that nobody's mentioned yet — your AC Input current limit within the ESS assistant itself.

Ooh this is really interesting — I've been meaning to sort out proper local logging on the narrowboat for ages but keep putting it off because it feels a bit complicated! Quick question for anyone...
Been running our place on a hybrid setup for about four years now and honestly the satisfaction of watching those energy bills shrink to almost nothing never gets old.

AngliaOffGrid | 1,203 posts | East Anglia @WayneTaylor welcome to the forum — good first question, straight to the point. @Jason1992 and @HazelHermit have covered the obvious import headaches, so...
The angle nobody's mentioned yet — what are you charging from? I ran a similar setup last summer whilst touring the South Downs in my van.

Nessa | 312 posts | 🔋 Batteries & EV Charging @PanelRoger Welcome to the forum — this is exactly the right place to be asking these questions. The static caravan I run off-grid convinced me...

@TracyAllen good shout on the regulator — had exactly that on my boat last winter. Swapped out a perfectly fine-looking regulator and the 20-minute cutout vanished immediately. One thing nobody's...
@WayneJames keen to see the wiring diagrams when you get there. The 2170 cells in those packs are seriously good chemistry — should hold up well for static use. One thing worth looking into early:...

Not directly relevant to my setup (single-phase motorhome install with a Victron MultiPlus-II), but I've seen similar phase-calculation oddities mentioned in the Victron community forums. Worth...

Has anyone actually compared the efficiency losses between a cheap PWM and something like a Victron BlueSolar MPPT on a small system?

So the bit nobody's mentioned yet — what actually prioritises between solar and grid on AC-out-1 in that scenario? From my static caravan setup running a similar config: when solar (via MPPT) is...
@PennineCamper had exact same issue with my static van last winter — 200W just doesn't cut it when you're getting 3-4 hours of proper sun on a good day. Ended up adding a portable 100W panel I can...
@AnneWatson's point about BMS disconnection is worth pursuing — is your MultiPlus set to ESS or standalone inverter mode?
Done this on my narrowboat for the past two winters so can offer some real-world numbers. A decent small chest freezer (I run a Sealey 35L) averages around 25-40W depending on ambient temp.

@Tel1968 worth checking your AC Input Current Limit in VE.Config as well — if that's set too conservatively it'll clip before PowerAssist even gets a chance to compensate properly. Also, what's...
Depends massively on what you're calling "basic" tbh. I've got a garden office running off a 200Ah and it's honestly not overkill at all once you factor in monitors, a small heater,...

@Midge52 I know exactly what you mean. Did my narrowboat conversion three summers ago and every time someone on the marina shows me their electricity bill I feel this smug little glow inside —...

@JackeryGuy the EV charging angle is what interests me most here. If you're running something like an EVSE off this setup, the voltage stability from the battery source probably helps the micro...
