Ha, @VoltageViking, duck contributions are a whole other category of panel contamination! 😄 I'm on a static setup in the Welsh borders and the oak pollen this spring has been something else —...

Been through exactly this with my shepherd's hut setup, so hopefully some of this is useful even though you're in a van. The short answer is: one leisure battery almost certainly isn't enough,...
@LizStewart — on the MultiPlus-II, "Solar Priority" is essentially achieved through the ESS (Energy Storage System) assistant rather than a standalone toggle.
SimonThompson replied: Had this on my narrowboat setup too — worth checking your alternator output voltage under load.
@ExSquaddie49 When you say they cannot be paralleled — are you referring specifically to the parallel function in the traditional Victron sense (same model, same firmware, VE.Bus synchronisation),...
Been running a Growatt SPF 3000TL on my narrowboat for about 14 months now and it's held up reasonably well, though I did have an early firmware headache getting it to communicate properly with...
Seen this exact gremlin in my motorhome — Victron's low battery threshold is calculated against a loaded voltage, so if your BMS is reporting resting voltage but the Multiplus is measuring under...
Running a narrowboat and trying to figure out if a single 200Ah lithium (Fogstar Drift 12v) is going to cut it for keeping a small chest freezer going overnight without the engine running. The...

@Renogy_Pro what current output are you actually getting through to the 20Ah though? With such a small bank I'd worry about over-speccing the charge rate and stressing the cells — most B2B...

Been having a weird one with my Victron ESS setup in the shepherd's hut lately and wondering if anyone else has seen similar. My system is single phase rather than 3-phase, running a Multiplus-II...

@NotAnElectrician80 makes a good point on ESS — worth adding that once ESS is configured, you'll want to set your minimum SOC carefully so the system isn't constantly trying to discharge to grid...
Had something almost identical happen with my setup last year — Victron Multi-RS 48/6000 refusing to budge out of storage mode even though the JK BMS was communicating perfectly with the Cerbo GX.

CamperSam replied: @SmartSolar_Queen Right, ignoring the forum gobbling up half these posts like a hungry seagull... Classic MultiPlus charger dropout.

Been having a nightmare with this exact thing on my narrowboat setup and wondering if anyone else is seeing it. Running a Cerbo GX alongside a pair of Victron SmartSolar MPPTs and a MultiPlus-II...
Really useful thread this. Following @VivaroWanderer and @Ben1960's points on parasitic loads — one thing I've been trying to get my head around for my van build is whether it's worth fitting a...

Running into something similar with my shepherd's hut build and wondering if anyone else has hit this wall. Setup is: Multiplus-II 24/3000 (latest firmware) Cerbo GX (v3.73) SmartSolar 150/85 2x...

@Frank1969 curious what your setup was when that happened — AGM or flooded? For anyone considering this for a van conversion, worth flagging that the MS-PAE 4448 isn't exactly compact.
Good point from @CurrentAffairs on the app config. One thing nobody's touched on — check your input voltage under load.

Had similar grief with my Quattro in the motorhome last year. Worth checking your generator's Hz output under load — mine was drifting badly once the EV charger kicked in and drew heavy current.
@Boycie25 good catch on the VE.Bus conflict — that one bites people hard. One thing nobody's touched on yet: assistant switch / remote on-off terminal.
