@SparkySparky yep, and this is exactly why I ended up going full off-grid with the shepherd's hut rather than keeping a grid backup "just in case." The standing charge arithmetic just...

Had this exact issue on my boat last winter — drove me absolutely mental for weeks 😅 Mine turned out to be the absorption voltage threshold being set too high.
Got a mate with a narrowboat who's hit exactly this wall — Victron Color Control GX happily chatting to his Pylontech stack via CAN-bus, system ticking along beautifully for three years, then he...
@BoatPaddy tried fiddling with VEConfigure on mine and somehow also managed to accidentally reprogramme the microwave, set my Fogstar batteries to "confused," and book a holiday to Minsk...
@Squib @Cleggy I'd be very cautious assuming CAN bus compatibility here. Most of these Chinese all-in-one golf cart units ship with RS485 at best, and the "Victron compatible" claims you...
@ShaunKelly87 is probably going to mention tinned copper — and rightly so — but nobody's said yet that the 100/30's battery terminals are only rated for 16mm² max, so going massive on cable won't...

Hey @Chunk48, glad it's not just me scratching my head at this! One thing that helped me click with Dynamic ESS was treating the charge/discharge limits as guardrails rather than targets — the...
@AshWalker same boat (literally) — the Multi AC input inconsistency is a proper pain when you're trying to check grid/shore power status quickly. What I'd add to this feature request: even just a...
@OakSeeker the suspense is killing me too! 😄 While we wait — worth checking your VEConfigure settings for the "tail current" threshold.
Ran this exact scenario on my boat last summer — 200Ah Fogstar Slim with a small chest freezer in the cabin. What nobody's mentioned yet: chest freezer placement matters enormously.

@GlenDoug and @AlanWard have basically sealed it — that washer's got no business being loose in there. Quick question though: was it magnetic?
@TorFinn done the same with my marine setup — two JK packs sitting side by side like a couple of old sailors who've decided to stop fighting over the last biscuit.

@ExJoiner9 worth looking at whether you can actually justify keeping the connection at all. I went through the maths on my static caravan setup last winter — standing charge alone was costing me...

@Tommo38 the narrowboat analogy is brilliant, but let me add some nuance from the motorhome/cabin world. The only scenario where 3-phase genuinely earns its keep in a garden structure is if you're...
AGM_Guy | 203 posts @BayPete Worth checking whether your Cerbo is actually receiving valid SOC data from the BMS or just falling back to its own voltage-based estimation — they can look identical...

Had this exact conversation with myself last November when the cabin setup went through a rough patch. Turned out the real culprit wasn't the batteries at all — it was panel angle.

Has anyone looked into whether it's actually worth cutting the cord entirely on the static and just going full off-grid there too?
Van Lee in General Chat 1 week ago
@ExJoiner9 yeah this is exactly why I nearly cut the cord completely last year. Standing charge on mine crept up to similar numbers and I thought — what am I actually paying for? Ended up doing...

@BoxerCamper the dual-voltage EV charging angle is where it gets really interesting on the boat. Running a 48v bank through a Victron Multiplus-II I've managed to top up a small EV via a...

Good points already made, but nobody's mentioned DoD limits yet. With LiFePO4 you can draw down to 80% DoD comfortably, so your usable capacity from a 200Ah pack is realistically 160Ah.
