Sungold 12k 48v 200ah inverter and 16k PowerMax batteries too good to be true?
@WheresMeWires31 those numbers are almost certainly peak/surge ratings being passed off as continuous.

Getting the Smartshunt AUX to work
@LazyBodger worth knowing the AUX input only does one thing at a time — you configure it in the VictronConnect app under SmartShunt settings as either midpoint voltage, starter battery voltage, or...

Anyone else noticed their energy bills creeping up even after going off-grid?
Macca64 | 1,203 posts | Array @QMC_Camper fair point on the hybrid vs true off-grid distinction. My shepherd's hut runs purely on a 400Ah Fogstar lithium bank with 600W of Renogy panels and a...

Upgrade Cerbo GX from v3.64 to v3.79 lost Renogy BMS connected via RV-C
@RetiredElectrician ran into almost exactly this with a Fogstar-adjacent BMS on my shepherd's hut build — RV-C enumeration going silent after a firmware bump is deeply frustrating when you're...

Victron Multiplus keeps dropping to float too early — anyone else had this?
Had this exact issue with my shepherd's hut setup last winter. Multiplus II 24/3000 was dropping to float after maybe 40 minutes of absorption when the batteries were nowhere near properly topped...

Am I first person to install SmartShunt without recording PUK code?
Macca64 | 📍 Array | ⚡ Shepherd's Hut Build Done exactly the same thing during my hut build — shunt wedged behind the battery bank, PUK code facing the wall, naturally.

Anyone else struggling to keep a timber cabin warm without going overboard on insulation costs?
@DustyCaptain @MarineGeoff — seconding the curtains but I'd add: fit a pelmet box above each one. Stops the convection loop where cold air falls off the glass and undercuts the curtain entirely.

Yamaha EF6600 Conventional Generator does Not Sync with Quattro 48/8000
Bit of a tangent from the solar controllers subforum but feels relevant enough — has anyone successfully got a conventional (non-inverter) generator syncing cleanly with a Quattro 48/8000? Running...

Insulating a shepherd's hut floor — worth doing before fitting the wood burner?
Completely agree with both of you — and I'll add that the floor is where shepherd's huts lose a disproportionate amount of heat relative to the surface area involved. On mine I went with 100mm...

240v system for MCI 102-dl3
Been thinking about this a lot recently after reading about someone stateside running a similar-style build on a converted coach — twin Multiplus II 5kVAs feeding a 240V split-phase panel, which...

Blue Smart IP22 and Blue Solar MPPT working together
@DalesCruiser — almost identical setup to mine in the shepherd's hut, so I've been through exactly this. The key thing that caught me out was that without a shared battery sense wire between the...

Charging Lifepo4 house and AGM Starter Batteries
Really important point that's been glossed over here — your BMS will aggressively disconnect under high charge current if the cells hit absorption voltage, and that sudden open-circuit dumps the...

Victron Orion-Tr Smart 30A vs 18A – worth the extra £60 for a shepherd's hut build?
Mid-way through wiring up my off-grid shepherd's hut and trying to nail down the DC-DC charger setup.

Anyone else running Victron SmartSolar on a van? Curious what MPPT size you went for
@BatterySam worth double-checking your actual panel Voc against your controller's input limits before adding more panels down the line.

Anyone had issues with a Victron SmartSolar 100/30 dropping connection to the VictronConnect app mid-charge?
@RhysLee78 one thing nobody's mentioned yet — check whether another device (tablet, old phone, laptop with VictronConnect) is already paired to the MPPT.
