Been having this exact issue with my Orion 30A in the van. Every time I pull up to a junction or hit slow traffic, the engine drops to idle and the Orion cuts out — then kicks back in with a clunk...

Seeing a few mentions of this issue on other forums so thought I'd raise it here too — anyone else on Venus OS v3.71 noticing their AC load readings freezing after roughly 10-15 minutes on the new...
@ExBrickie makes a solid point on tail current — that caught me out on my own setup too. One thing worth adding: check your battery temperature compensation if you're running without a Smart...
Just had my latest statement through and it's gone up again — third time this year. I'm on a floating tariff which clearly isn't doing me any favours right now. Honestly it's one of the main...

Been thinking about this a lot lately for my motorhome build but it applies to my tiny house setup too — what generator do you actually pair with a LiFePO4 system as a proper backup? My current...

Slightly tangential to the thread title but relevant enough I think — been through something similar expanding a Victron setup on a static caravan, and some of the lessons probably apply to a...
@DerekMoore89 mate, that's the narrowboat canal gods telling you something. I've got a similar rig on my boat — Multiplus-II GX, Fogstar Drift 48V bank, the works.
Good thread this. One thing I'd add for anyone going through the G99 application process with a Multiplus II 6k5 — Victron publish a dedicated compliance document pack specifically for the DNO...
Bit of a niche one but wondered if anyone else has run into this with their Cerbo GX setup. When CCL drops to 0 (charge current limit, usually when the BMS is saying "stop charging"),...
@George1972 raises the exact question I'd want answered. On my narrowboat I trialled a similar budget inverter before settling on a Victron Multiplus, and the fixed-speed fan was genuinely the...
@ExJoiner32 2,000 hours of sunshine — don't remind me, I'm sitting in my shepherd's hut watching horizontal rain batter my 200W Renogy panels for the third week running 😅 The one thing I'd add for...
@PartnerBuild yeah this exact thing drove me mental on the boat last summer. Multiplus kept screaming low battery, BMV-712 sitting there saying 12.8v, totally fine. Ended up being a dodgy crimped...

SD_Sparks | 1,203 posts Worth adding to what @LiFePO4_King mentioned — ambient temperature makes a surprisingly big difference here.

EssexNomad | 847 posts @MarinePhil narrowboat solidarity — mine was basically a draught-powered refrigerator until I fitted a Webasto and stopped pretending the original 1970s foam was...

@GafferTapeKing that cold January failure is a concern — my garden office setup needs to be reliable year-round, not just when the weather plays nicely. One thing I'm trying to work out with these...
Good shout from @BoatClive on the data cables — I'd add that the power connector on the Cerbo itself is worth inspecting closely.
@BaySeeker that logging approach was exactly how I sorted mine for the cabin build — once I could see the actual voltage curve over a proper drive cycle, the answer was obvious.

Great thread @DODQueen, and nice to see Fogstar Drift cells getting a mention — I've got a similar setup in my static caravan and they've been brilliant. One thing worth flagging that nobody's...
@HeathOllie all valid, but the practical workaround in my motorhome is just letting the Victron handle it via voltage-based charge control — set your absorption to 57.6V (3.6V/cell × 16), float at...

@ExBrickie is right but let's be specific about why this particular unit concerns me. That Renogy's MPPT is rated at 80A input — fine in theory — but the charge controller, inverter, and charger...
