Had one on my garden office build for about six months. Solid enough unit for the price, but the BMS communication is basic — no proper CAN bus integration if you're running a smart lithium bank...
OffGridJulie | 🚤 Liveaboard Lunatic | Posts: 412 Mine's been logging Fogstar battery data since last spring and the only "complex" bit was explaining to my boat neighbours why there's a...
Not a cabin build myself but we dealt with chronic condensation issues on the narrowboat over a couple of winters, and a lot of the same principles apply with timber frames honestly. The thing...
Bit of a rant incoming but has anyone else noticed Victron's VRM portal getting increasingly fussy about how you log in? Running a Cerbo GX on my van build and I've just had grief trying to access...
Spent two summers running a cheap PWM unit from Amazon — one of those no-name 30A jobbies that arrived in a box with instructions translated from Chinese via something that wasn't quite English.

@FETFan "premium" is one of those words that instantly makes me suspicious tbh. Had a bloke try to flog me a "premium" setup for the shepherd's hut a while back — turned out to...

@Squib82 raises something important there. One thing I'd add from my own experience running a similar Orion-Tr Smart setup — check your alternator type before assuming the 30A output is safe...
Good points from @FormerMechanic14 and @BoxerCamper. One thing worth adding — cell matching in budget packs is often poor.

Has anyone actually mapped out which digital inputs on the Cerbo GX can be configured as outputs via Node-RED versus which ones are genuinely input-only at the hardware level?
Great thread @T6Solar. The classic single-point-of-failure problem. For cabin setups (my world), I run two Multiplus-II units in parallel — if one throws a wobble, the other carries the load...
Really crucial detail nobody's picked up on yet — the ET112 placement matters enormously here. If your ET112 is on the grid feed before your loads rather than after, the Multiplus-II can get...

@ExSquaddie classic case of the BMS and Multiplus not agreeing on what "full" actually means.
@Renogy_Nerd I get the scepticism, but the solar/battery sizing angle is what's catching my attention here. Most monitoring tools tell you what happened — fewer help you plan what you need.

@Chopper54 the "kitchen floor rehearsal" is a rite of passage nobody warns you about. I've done the same thing on my narrowboat — except on a boat you're also simultaneously discovering...
Good points from @PanelEwan and @BirchLover already, but one thing worth considering that nobody's touched on yet — the Orion-Tr Smart's output profile when charging LFP. The default...

@BoxerWanderer "because t" — because the universe enjoys chaos? Because termites? Because time itself is a flat circle?

@MarineVicky v3.79 — the firmware equivalent of that one family member nobody mentions at Christmas. Worth checking your current version in VictronConnect before losing any more sleep; if you're...
@ZoeRoss not a daft question at all — phase rotation is absolutely worth ruling out first, it's a 5-minute fix vs hours of head-scratching. @VoltWendy on the rattling — don't ignore that.
@DorsetSolar eight months is actually a decent trial — long enough to see it through a proper UK winter which is the real acid test for any inverter/charger combo. I've had the Renogy 3500W...
@Pete1994 had this exact farce with my static van setup — turned out my MC4 connectors had corroded faster than my faith in British summers, dropping just enough resistance to make the whole thing...
