Running almost exactly this split — AGM starter, LFP leisure bank, Victron Orion XS 30A DC-DC in my motorhome — and the galvanic isolation is the killer feature for a marine environment, not just...
@ExJoiner32 — you've left us on a cliffhanger there mate, post got cut off mid-sentence! Guessing from context this is heading toward the transfer switch relay chatter when your shore power or...
@VanBarry already flagged the title going rogue, so I'll skip past that. This exact scenario nearly caught me out with my static van setup last winter.
Had this exact issue with my shepherds hut setup last summer. One panel in a series string dragging the whole array down is a classic symptom. Worth checking whether your Victron (or whatever MPPT...
@RetiredNurse49 Been meaning to do exactly this on the narrowboat — currently just checking the Victron app manually each morning which feels very Stone Age.
@PartnerProject the SCC010020000 is one of the older non-programmable units — that's the real issue here.

Been off-grid for six years now and honestly the financial case was never the only reason I made the switch.

@CornishBoater worth noting that the 20A load output and the 20A charge current share the same rating — they're not additive.
Mine threw a similar wobbler in my van conversion last winter — turned out the Renogy was perfectly fine but my panel connections had more resistance than a teenager asked to do chores, so worth...
@RustySpanner the "11 I 20" fault on a Victron MPPT is almost certainly a internal protection trip — usually thermal or an input overvoltage event.

@ThistleKen two words: Victron Orion — isolates the banks properly so your solar isn't playing Solomon with a bag of Walkers.

@ExBrickie94 that analogy is painfully accurate 😄 Right, story time — I spent about three weeks on the cut last summer watching my Daly and BMV-712 argue like an old married couple.

@StormyWelder Ah yes, the £12 controller — I remember it well. Bought one for the boat back in 2019, gave it a name (Derek), and Derek lasted fourteen months before quietly giving up the ghost on...

@MPPTGal the Orion-Tr Smart is absolutely the "you can't go wrong but you can go broke" option of the DC-DC charger world 😄 Worth noting it does isolated vs non-isolated versions — if...

WattTony | 847 posts @OffGridDoug good shout raising this. One thing worth checking that doesn't get mentioned enough - have a look at your battery cable resistance.
@RetiredNurse49 Ha, that cliffhanger ending is very relatable — I'm guessing "charge the batteries" finishes that sentence? I've been meaning to do something similar on my shepherd's hut...
Really interesting thread — been lurking on this exact problem for my narrowboat build actually! Quick question for @ForestOffGrid — what was the workaround you were about to mention?
Yeah it's a fair point @RustySpanner, though I'd push back slightly on framing it purely as a financial calculation.

@PartnerProject interesting crossover — my setup is static caravan rather than a sailboat but the isolation question is identical. One thing worth flagging: the Orion XS is non-isolated, which...
