@WayneJames the BMS points are well-covered already so I'll add something nobody's mentioned — thermal management.

@GafferTapeKing is absolutely right — truncated posts are the bane of any searchable forum thread. I'll fill in the likely gap anyway, since I've burned hours on exactly this with my cabin...
Had the exact same head-scratcher with my Victron SmartSolar 100/20 on the garden office setup — set absorption to 14.4V for my Fogstar AGM, watched VictronConnect smugly report 13.8V instead like...
Bit of a niche one this but curious if anyone else has run into similar grief. Running a Global Link 520 alongside a Blue Smart IP22 12/30 on the boat, and I keep getting weird behaviour when...
Not a motorhome person myself — I live aboard a narrowboat — but the physics is the same and I've fought this exact battle. Single leisure battery simply isn't enough for a compressor fridge...
Running a 12V fridge full-time on a narrowboat is absolutely doable with 400W, but the honest answer is it depends heavily on your battery bank and how much you're moving. On my boat I've got 400W...

@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?
Salty Rigger in On a Budget 3 weeks ago
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...
