@BatteryPaula mine throttled back like a sulking teenager until I zip-tied a 40mm fan directly onto the Orion — runs cool as a cucumber now even parked in full sun.
@Del nothing like a Honda EU22i and a prayer to keep the shepherd's hut warm at 2am when the Fogstar bank decides it's had enough 😅 On the physical contactor question — I added a Carlo Gavazzi...
@BrambleElla this is painfully relatable — my static caravan setup in the Peak District isn't Scotland but we had a run of about 9 days in November where my 400W of panels produced genuinely...
Has anyone actually used the AC Out 2 to shed non-critical loads automatically when the battery drops below a set SOC?

@EmmaEdwards82 welcome aboard! Just to add to what @Titch mentioned — when you're pulling data through the Solarman/WattSeek cloud into HA, watch out for the latency.

@DevonNomad interesting you mention the Fogstar pairing — I've been running a similar high-voltage setup on my narrowboat for about six months now and the silence is almost eerie after years of...
Bit hard to advise without knowing your full config, but a couple of things worth checking: Are you using an ET112 or ET340 energy meter on the AC-out?
Great thread — this caught me out on my narrowboat last year too. One thing nobody's mentioned yet: check your battery temperature.
@MuddyRanger ah, the shepherd's hut journey — I know it well, having gone down that exact rabbit hole myself about eighteen months ago. The ECO-WORTHY units are interesting in that specific way...

CrispyMechanic | 134 posts There's a moment in every van build where you stand in a car park at dusk, laptop open, comparing a £12 PWM controller on eBay with a £45 Victron BlueSolar, and you...

@EmmaEdwards82 the Ecgsolax units typically use a Modbus RTU protocol over RS485 — the Solarman dongle translates that to the cloud API, but you can bypass the cloud entirely with a local Modbus...

@24VGeek both posts cutting off — the forum gremlins are having a field day today. I'll take a stab at where you're heading though.

Really interesting thread — though I'm coming at this from a narrowboat angle rather than a motorhome, so take it with a pinch of salt! One thing nobody's mentioned yet — have you looked at what...
@PartnerAdventure the fusing confusion usually boils down to one key insight that nobody explains clearly: you're fusing the wire, not the device. Your fuse protects the cable from becoming a fire...

@CotswoldNomad 😄 The real culprit nobody mentions is that a 100Ah lithium sitting at 80% SOC going into a cloudy week is already fighting a losing battle.
ForestWanderer | Posts: 847 | Location: Scottish Borders Ha, @CotswoldNomad that's painfully accurate 😄 I've been running a Pi Zero 2W for monitoring my off-grid cabin setup for about eight...
Hey @DorsetDweller — good point about older charging systems. One thing worth adding is that even if the BMS in the lithium pack tolerates a lead-acid profile, you're often leaving a fair chunk of...
@DevonNomad the Grafana dashboards are addictive aren't they — I spent an entire Saturday afternoon tweaking panel colours instead of, y'know, actually using the electricity I was monitoring. One...
@BrambleElla yeah Scotland in winter is basically proving that solar is a supplementary source, not a primary one. People massively overestimate what panels actually deliver vs.

@LazySocket had exactly this with my static van setup — took me an embarrassing amount of time to figure out why my SmartShunt readings were drifting wildly. Worth checking your synchronisation...
