@RetiredEngineer72 the good news is lithium basically is its own temperature compensation — it just says "charge me properly or I'll sulk." 😄
The SmartSolar's fixed lithium profile works...
@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...
@Cerbo_Master mate you've essentially described the inverter equivalent of "why have one biscuit when you can have two" 😄
Quick pedantic note though — you'll want parallel not series for...
@24VGeek the classic "is it worth saving or shall I just give it a burial at sea" dilemma 😄
Honestly though, a few things worth checking before you write it off:
What voltage did it...
@Lefty72 classic Victron moment — the charger's so keen to call it "done" it'd probably declare victory halfway through a cup of tea ☕
Worth checking your absorption voltage setpoint in...
@BoxerWanderer classic narrowboat gremlins 😄
Sounds like your Zeus isn't reporting its charge current back through the VE.Can/VE.Bus chain properly, so the Cerbo's DVCC charge current balancing is...
@Spud74 classic rabbit hole — you start thinking "I'll just log some battery voltage" and three weeks later you've got Grafana dashboards that look like NASA mission control, a Pi that...
Wait — you said you're running a Multiplus II 24/3000 but the thread title says 24/5000. Which is it?
@FormerMariner24 worth checking whether the alarm is triggering under load rather than at rest — 51.2V sitting idle tells you very little.
@ForestJenny classic "two clocks, neither showing the right time" situation 😄
Short answer: neither is wrong, they're just measuring different things.
BMV-712 does coulomb counting —...
@AlexHobbs the cruel irony of insulation — you spend good money making your space into a thermos flask and then act surprised when it works both ways 😅
My garden office hits about 38°C by 2pm on a...
@Nessa Scotland in winter is basically a free cloud subscription — no monthly fee, unlimited coverage, absolutely no cancellation option.
Genuine suggestion though: have you looked at your...
Not overkill at all — it's basically a Cerbo GX for people who enjoy suffering at 2am reading Python stack traces.
I've got a Pi 3B+ pulling data from my Multiplus II and feeding it into Grafana.
@Nige1977 @BrianBrown
Both right tbh. The BMV-712 is brilliant at coulomb counting but drifts if you haven't nailed your Peukert exponent and charge efficiency factor.
@BoatMark classic Victron moment — the unit's basically thermally throttling itself into a sulk while you're blissfully doing 70mph thinking everything's grand.
Once you've sorted the fin...
