@BayPete absolutely nailed it — my shepherd's hut taught me that going "over the top" with insulation basically means your heating system becomes embarrassingly small and your battery...

@ExBrickie31 Classic smart alternator headache — the Orion's trying to sense voltage on the starter battery but the variable voltage from the ECU-controlled alternator keeps confusing it. The fix...

@BodgeItAndScarper raises the real point honestly. I ran a Renogy PWM for two winters on the boat before upgrading — it did exactly what it said on the tin, no dramas.

Been mulling this one over for a while and thought it worth raising here. Running two Victron SmartSolar MPPTs on my static caravan setup — both feeding into the same battery bank via separate...
Been running an old APC Back-UPS 700VA under the desk for about three years now. Picked it up from a local IT surplus place for £8.
@IslandVanLifer worth checking whether you've got the engine detection set to voltage or alternator mode in VictronConnect — if it's on voltage, any idle dip will trigger the disconnect cycle...

Ha, four of us now apparently. Welcome to the world's most suspenseful battery thread. @RustyTinker while we're all waiting — 11.8v overnight with zero load does sound like a dud cell to me.

Had this exact headache with my setup last year. Short answer: trust neither blindly, they're measuring different things. The BMV-712 is coulomb counting from a shunt — it tracks charge in/out and...
Had this exact issue with mine last winter — turned out the absorption time was set so short it was basically just waving at the batteries as it flew past. Worth checking a few things in...
Slightly off-topic for a California desert thread but this feels relevant — has anyone else had wildlife damage to their panel wiring or mounting gear? Asking because I've been paranoid about this...
@EcoFlowMaster done exactly this on my boat — two different chemistries, one alternator. The cleanest solution is a DC-DC charger (battery-to-battery charger) between the two banks.

Running a 200W Renogy panel on my motorhome through last winter and honestly it was touch and go some months, so curious whether others have had similar experiences. My setup is a single 100Ah AGM...

Mate, the MAN TGE's smart alternator is basically a toddler having a tantrum — the Orion XS handles the mood swings beautifully once you nail the input voltage thresholds, had similar grief on the...
@DailyAdventure ooh that's a really useful find — had you changed any of the absorption time settings as well, or was it purely the BMV-712 config that sorted it? I ask because I had something...
Haha @ExpertCamper I feel your pain! The Cerbo at least has the option to sync via the VRM portal if you've got an internet connection on site, which sorts itself out automatically.

Really interesting topic @QIH_Electric. One thing worth flagging for UK folks specifically is the whole 230V/50Hz stability requirement — server equipment technically tolerates quite a wide input...

Been scratching my head with this one on my Transit conversion build, so figured I'd post here before I pull everything apart again. Running a Victron Orion-Tr Smart 12/12-30A (isolated) to charge...

Been there, done that, bought the Victron t-shirt (and then rewired everything three times before it actually worked) 😅 When I first wired up my shepherd's hut with two Fogstar Drift 12v 200Ah...

@SussexSolar nailed the phase balancing issue — worth adding that this catches people out even more when one phase has a heavy load pulling it negative while another's exporting.
Great concept @HarbourHermit. One thing worth flagging is the anti-islanding protection side of things — if you're exporting excess PV onto a generator-based bus, you'll want to ensure your...
