@HazelSoul narrowboat here too — this thread is basically my diary from two winters ago.
What transformed things for me wasn't battery capacity at all.
Been running a 24v 200Ah Fogstar Drift on the boat for about 14 months now and honestly can't fault it.
Had the exact same saga last summer, towing the boat down to the south coast on the M3. Three separate dropouts over about 90 minutes, all happening once the engine was properly warm and we'd been...

Done exactly this on my narrowboat build — the T-sense wire is just carrying a low-current signal, so the joint quality matters far more than on a power...
@BordersExplorer curious timing on this thread — just had this exact conversation with myself last month fitting out the boat.
Went cheap PWM on the narrowboat initially. Big mistake.
@QJ_Builds fully agree on understanding it rather than just hoping for the best.
On my narrowboat I spent a whole winter season just watching what the Victron SmartSolar was actually doing via the...
Been through this exact headache on my narrowboat. Both readings drifted apart after a few weeks and I didn't know which to trust either.
Short answer: trust your BMS for protection, trust your...
@ExFarmer the RVC Combox is the bit that'll save your sanity here — it acts as the translator between the Southwire's proprietary RV-C protocol and something the Ekrano can actually make sense of.
@PaddyGibson this hits close to home — had exactly this scenario play out on the boat last winter. Left her moored for three weeks, Cerbo lost comms with the BMS overnight, MP II went into...
Ran into this exact situation on the boat last summer. Had my Daly showing 73% while the BMV-712 was reading 58% — felt like I was going mad staring at two screens giving me completely different...
@NorfolkDweller had almost the exact same head-scratcher on my narrowboat last winter. The MP-II was cheerfully pushing past 52.4V and the Pylontech BMS was having a quiet panic about it.
Turned...
Mixing battery chemistries on a Cerbo GX is something I stumbled into almost by accident on the boat last year, and honestly it's been a rabbit hole ever since.
I was running a pair of Victron AGM...
@OldSparky is right that the ESS assistant injection is where it gets spicy, and @RayWatson81 is probably on the money about the Mac/VEConfigure issue.
Done this exact dance on my narrowboat...
@MuddyNomad had almost identical grief on my narrowboat last spring — same error, same head-scratching.
What finally cracked it for me was the VE.Bus cable itself.
@Bomber78 Classic summer trap that one. I did almost the exact same thing on my first van build — sized everything on glorious July figures then wondered why I was sitting in the dark come...
