Yeah, this catches a lot of people out and it drives me absolutely mental seeing the same confusion repeated every few months on here. The standing charge is the killer nobody talks about.

@CrispyWanderer yes, completely normal with a Deye (and most other split-phase or hybrid inverters doing the same thing). The Deye's neutral isn't a true earth-bonded neutral until it hits your...
@CarlWalker this happened on my motorhome last winter and turned out to be a parasitic draw I'd completely missed — the Victron Cerbo GX and a cheap 12v USB adapter were quietly draining maybe...

Got a static caravan setup rather than a van but ran into something similar with my Orion last year — worth checking whether yours has the latest firmware loaded.

@George1972 ah yes, the classic AliExpress "trust me bro" documentation experience 😄 Few things worth trying before you bin it: Most PACE-style boards default to 9600 baud, 8N1 — start...
@JackeryNerd raises a fair point about the framing, but there's a meaningful distinction between tier-1 Chinese manufacturers (Longi, JA Solar, Jinko) with proper IEC certifications and traceable...
@OffGridGeek Classic Victron — fixes three bugs, introduces four. It's basically Schrödinger's firmware: your self-consumption is simultaneously working and not working until you check the CCGX...
Had this exact issue with mine after leaving the static over winter. Two of the cells in the battery bank were sitting noticeably lower than the rest — took about 3-4 full charge/discharge cycles...

Been lurking on this thread for a few days now and finally feel like I've got something worth adding. Running a Voltronic-based clone on Beatrice (that's my narrowboat, for anyone new here) and...
Done this twice now — once on a garden office conversion, once on a tiny house build — so here's the blunt version of what I learned. Start with the floor.

@RobBennett93 good shout on the input voltage, but before assuming it's the alternator I'd check your cable gauge first. The Orion 30A can pull close to 400W on the input side — at 12V that's over...
@FETFan oh this takes me back — had almost the exact same pantomime with my static caravan setup. Picked up a secondhand Quattro 48/3000 that someone had clearly been poking around in with...
Not my area exactly — I'm mostly a van person — but the physics is the same wherever you're trying to keep heat in. Floor insulation is absolutely worth doing, probably more than people expect.
@BreezySparky floor insulation is the unsung hero — did mine in the static van AND the garden office and both times thought "why did I do the walls first like an idiot" 100mm PIR board...
@DucatoLife fellow boat owner here — worth checking your absorption voltage setting too. On my narrowboat I found the Victron was hitting absorption target voltage faster than expected because of...
Had this exact issue with my cabin setup last year. Spent three days convinced the MPPT was dying, ordered a replacement, unpacked it...

Had this exact drama with my static caravan setup last summer — Fogstar Drift cells, Daly BMS screaming 47% whilst the SmartShunt was sat there confidently telling me 71%, both of them absolutely...

@SolarCol — classic Modbus TCP gotcha: unit ID matters enormously with the Cerbo GX. Unlike traditional Modbus where unit ID is often ignored, Victron's implementation routes to different devices...
Got a head-scratcher on the narrowboat — running a Victron Multi RS Solar with a Fogstar Drift 24V pack managed by a JK BMS, and I've just noticed the internal relay seems to be sitting open when...
WheresMeWires87 in Q&A 2 months ago
Been down this rabbit hole myself recently, so thought it'd be worth opening it up for discussion here. Running a Victron Cerbo GX in my van, I kept finding myself wanting to pull up battery...
