@Nobby mine did something eerily similar in the static van — turned out the DC cable run was way too long and undersized, so the MultiPlus was seeing a completely fictional voltage at its...
Scotland in November is basically a solar panel's worst nightmare — you're generating about as much useful power as a damp potato.
@T5Wanderer raises something important, but I'd add one more layer to this story — temperature compensation. My Fogstar Drift cells in the back of my Sprinter used to trigger early absorption...
@BoatMark been down this exact rabbit hole with my Orion-Tr Smart 30A. One thing nobody's mentioned yet — wire gauge matters more than people realise.

@DodgyMechanic the consumption forecast bit genuinely feels like Victron designed it specifically to humble overconfident engineers 😄 On my narrowboat I use the historical average method rather...

Had something eerily similar with my Victron IP67 12/17 on the boat last spring — plugged it in after a winter lay-up and the thing was convinced my 100Ah LiFePO4 was sitting at about 4 volts when...
Running a small garden office rather than a shepherd's hut, but the sizing question is identical so hopefully this is useful context. I'm currently trying to work out whether a 200Ah LiFePO4...

FormerTeacher50 | 234 posts | ⚡ Off-Grid Enthusiast @SolarTrevor Before you dive in, the key figures to check are your MPPT's maximum open circuit voltage (Voc) and short circuit current (Isc)...
Good shout from @Taffy55 on the GX, but if that's overkill for a straightforward dual-bank setup, worth knowing the BMV-712 actually handles two batteries natively — the main shunt monitors your...
@BurnWalker that's exactly what I keep going round in circles on with my static caravan setup. I've got Pylontech US5000s sat here waiting to go in and I can't get a straight answer on what Voc...
@SimonKelly yes, hit this exact issue on my motorhome setup. The problem is v2.08 introduced a stricter SoC threshold check in automatic mode — if there's no battery (or it can't read one), it...
Been through similar on my boat up around the west coast — Scottish summers look great on paper but the solar yield is genuinely poor for days at a stretch. Few things that made a difference for...
@LisaStewart71 looks like your post got clipped but I'm guessing you're asking about integrating a non-Victron inverter into the Cerbo's ecosystem via Node-Red?
The support headache is something I learned the hard way with my shepherd's hut build. Started out with a bargain inverter-charger nobody had heard of — looked great on paper, specs seemed solid.
Yeah @AZY_Marine has hit the nail on the head there. Standing charges are the silent killer for anyone trying to cut grid dependence.

Just seen this come up in a few places and wanted to flag it here too — has anyone else noticed a reverse polarity condition on the AC output with the Junbpaw 2080W unit? Been doing a lot of...

Has anyone actually pulled the trigger on one of these? I've been eyeing them up for my cabin setup and the spec sheet looks decent on paper — 314Ah at 48V is a serious chunk of storage for the...

Been mulling this one over for a while and thought I'd throw it out here. Running a Victron MultiPlus-II 48/5000 in my setup — Cerbo GX, Fogstar Drift lithium bank, ET340 on the grid tie — and...
@OffGridHamish Had exactly this frustration on the narrowboat. DESS doesn't expose its reasoning natively, but there's a practical workaround worth trying. Pull the MQTT data from the Cerbo and...
Done the same swap on my motorhome and the charger drama is basically a rite of passage at this point.
