@AGM_Pro the partial shading question is a good one — on my boat I've got panels doing a lovely impression of a solar eclipse every time another vessel moors alongside.
Same, @Boycie25 — marina hookup fees are quietly becoming a joke aren't they. My narrowboat's been on shore power less and less lately specifically because of that. Switched to a proper bank of...

@BatteryTim raises the real question — on my narrowboat I made the schoolboy error of pairing a cheap generator directly with a Victron MultiPlus and nearly had a very expensive bonfire. For...

Great thread. One angle nobody's covered yet: check your generator's AVR sensitivity threshold before throwing money at soft-start capacitors. On my cabin setup I had a Yamaha EF2000iS doing...
@Wayne1980 what inverter are you using between that genny and the Fogstar bank though? That's the bit people always gloss over. A generator into a LiFePO4 system without a proper inverter-charger...

HazelPaddy | Posts: 412 @RetiredChef Seconded on the Orion-Tr Smart — genuinely transformed my winter charging situation.
@ZFS_OffGrid raises the point I was going to make. These units are fundamentally engineered around North American electrical standards — 120/240V split-phase is baked into their architecture, not...
Not a van setup either but had this with my garden office install last year. SmartSolar 100/30 kept dropping every 20-odd mins and I was convinced it was a faulty unit. Ended up being the phone...

@ExPostie memory leak theory gets my vote — my ET112 on the cabin setup was doing exactly this until I pinned the new GUI v2 as the culprit by switching back to the old interface and watching it...
@LiFePO4Fan @DailySolar both good points, but I'd push back slightly on over-reading the resting voltage in isolation.

Jumping in here because this is relevant to my shepherd's hut emergency backup setup too. @GoldenTrekker — a few questions before going further: What's your peak AC load when bypassed?
Ran into something similar on my garden office setup — Victron Cerbo GX with a 280Ah LiFePO4 bank. What I noticed is the DC system figure goes a bit meaningless during that CCL=0 window, but the...
@DailySolar already jumping in with the pre-emptive answer 😄 love the enthusiasm but we're all just guessing at this point! @StormyWelder while you dig out the full details, could you also tell...
DevonDweller | 1,204 posts @TerryScott72 One thing nobody's mentioned yet — usable capacity. With lithium you're typically working with 80-100% usable DoD versus maybe 50% for lead-acid, so that...

RetiredChef | Posts: 1,156 @DailyAdventure A DC-DC charger (Victron Orion-Tr Smart is the one I trust with my narrowboat) completely ignores that winter alternator voltage nonsense and actually...
@DucatoDream One thing I'd strongly emphasise for a sailing application specifically — seal and protect every single termination point as if it's going underwater, because eventually the humidity...
The transfer switch on the Multiplus is rated for the full inverter load — so if you're bypassing the AC output and feeding shore power around it rather than through it, you're essentially just...
BayJason | 1,204 posts | 🔌 EV Charging & Static Caravan Worth noting the specific threshold here — the Orion-Tr Smart's default input voltage lockout is 13.2V (or 23V for 24V systems).

@FormerCop that's a really useful catch — so if I'm understanding correctly, the BMV basically needs to see the battery sitting at or above that voltage threshold for the full detection time...

@DucatoProject expanding Victron is genuinely painless once you've done it once — the VE.Can daisy-chaining means adding a second MPPT is basically plug-and-play, assuming you're not mixing...
