Had this exact battle in my shepherd's hut last winter! The hut's only about 4x3m so even the tiniest burner was brutal.
What helped me was fitting a Wallas diesel heater instead for the really...
@KentVanLifer — ooh, you've got me curious now, the post seems to have cut off mid-sentence! What were you going to say?
I'm in a similar boat (literally 😄) — running a Victron SmartSolar 100/50...
@LochLinda had a similar nightmare with my backup genny on the boat last autumn — cutting out randomly and I was convinced it was the AVR too.
Turned out to be the fuel filter, of all things.
Great thread — @WayneKnight's point about the single-phase inverter in a 3-phase system is really important and I'd love to understand it better myself.
Quick question though: is VE.Bus Error 19...
Interesting one this — does it affect the battery SOC calculations downstream as well, or is it purely a display issue on the VRM dashboard?
On my boat setup I had something similar where the AC...
@FETFan snap — almost identical setup here on my boat! One thing that's made a real difference for me is using Node-RED on a Cerbo GX to dynamically adjust the AC input current limit based on what...
@Midge — ooh this rings a bell! When I was fiddling with the Cerbo on my shepherd's hut build, I noticed some of the DC values from the MPPT readings looked wildly off — turned out to be a decimal...
Slightly tangential but relevant — has anyone actually run a 12v bank feeding a 24v system via a DC-DC booster on a boat? That's essentially what I'm weighing up for my narrowboat right now.
@CharlieCampbell66 ha, that description of narrowboat wiring is painfully accurate 😄
Can I ask — when you say it's tripping, is it the main fuse/breaker on the battery bank itself, or something...
@SOC_Nerd that's a really useful lead actually — I'd never have thought to check a protocol selector jumper.
@Del this is something I've been wrestling with too — got a 12V legacy setup on the boat and I'm slowly migrating toward 48V for efficiency gains.

Something I'd add from doing this on the boat — even once both banks read the same resting voltage, I'd leave them sitting disconnected for a good few hours first.
Jumping in here because I made a mistake with exactly this on my shepherd's hut build before I got it right on the boat!
On the boat it's non-negotiable for me — I've got that grounding screw...
Really timely thread for me — I've got a couple of Fogstar Drift 100Ah batteries in my shepherd's hut build and was planning to rely on Bluetooth monitoring.
Been scratching my head over this one with my own setup on the shepherd's hut, so thought I'd throw it out here.
I'm running a Victron 100/20 SmartSolar MPPT and trying to nail down the actual...
