Ran into this exact scenario when I built my DC-only shed setup — Cerbo GX coordinating two SmartSolar MPPTs and a Lynx Distributor, no MultiPlus anywhere in the chain.
The "Off"...
@CE_Builds is right about the sense wire, but worth adding — even with proper sense wiring, the absorption termination current threshold is often the real culprit here.
In VictronConnect, check...
Had this exact issue with my 100/20 last summer. Turned out the absorption time was set too short in the custom settings — Victron's default adaptive algorithm can be a bit aggressive in deciding...
Been doing a fair bit of research on the Multi RS Solar 48/6000/100 lately as I'm considering it as a potential upgrade path, and I've got a few questions I can't quite pin down from the Victron...
Interesting choice — AIMS is fairly popular in North America but you don't see them discussed much over here.
Running a small off-grid setup at my static caravan in the Peak District and trying to work out whether a single 200W panel is going to be sufficient to maintain a 100Ah leisure battery through...
@AlanJones63 the standing charge situation is genuinely absurd — I'm paying Octopus something like £1.10/day just to have the connection, before I've drawn a single unit.
@MultiPlusNerd worth considering whether your Fogstar cells have drifted out of balance over winter.

@PaulJackson The Daly BMS is the weak link here, frankly. It'll communicate nothing to your charger, so you're relying entirely on the BMS to hard-cut charging at full charge...
@QMC_Camper has already flagged the critical bit — Voc headroom — so I won't repeat that.
What I will add: three 200W panels in parallel keeps your Voc identical to a single panel, so if you're...

@GemmaWood the maths here is brutal and worth spelling out clearly. Your 400W array on a decent summer day might yield 1.5–2kWh. An EV needs roughly 6–8kWh per 20 miles.
@Pylontech_Wizard this is a known issue with the US2000 — the internal BMS recalibrates SOC via coulomb counting, and cold temperatures reduce actual capacity whilst the BMS hasn't yet performed a...
@Boycie the Daly isn't bad per se, but it's essentially a dumb protector rather than an active manager.

@GlenDixon one thing nobody's mentioned yet — check your DC input voltage sag under load. If your battery cables are undersized or connections are even slightly resistive, the Multiplus sees the...

Worth flagging something @OhmsLaw7 and @PV_Master haven't mentioned — the Venus OS Large firmware is what unlocks the proper Node-RED and Signal K...
