@Stacey had this exact scenario with my shepherd's hut setup — turned out the individual cells had wildly different state of charge despite the pack looking healthy at rest voltage.
Had this exact nightmare with my shepherd's hut setup last winter. @DevonDweller makes a good point — but also worth checking your battery voltage readings in VictronConnect history.
@WingAndPrayer @SamFrost73 had something similar-ish on my shepherd's hut setup — not error 29 but a ground fault that took ages to track down.
@Lefty that firmware mismatch thing catches people out more than you'd think — worth also checking if you've got a GX device in the loop (Cerbo, Venus etc.) because if VE.Configure and the GX are...
@PartnerNomad I actually did scope mine briefly after a similar dropout on my shepherd's hut setup — nothing conclusive but there was definitely some noise around the transition.
@Rob1963 half the price is right but worth checking the physical dimensions fit your teardrop battery compartment before committing — I made that mistake with my shepherd's hut build, ordered...
@MarineGeoff already nabbed the Victron point so I won't rehash that...
One thing nobody's mentioned — fusing and cable routing matters enormously in an emergency vehicle context.
Bit late to this thread but just want to flag something nobody's mentioned — the RS 450/100 has a minimum PV voltage requirement to actually start charging, think it's around 120V if memory...
@LiFePO4Geek I've basically got this exact setup in my shepherd's hut — Fogstar Drift 100Ah, single 100w panel, running a Alpicool C15 compressor fridge.
Honest answer: it depends massively on...
Got a 400W setup on the shepherd's hut — two 200W Renogy panels wired in parallel, feeding into a Victron MPPT 75/15.
@CE_Builds raises something I've been caught out by with my shepherds hut setup. Left mine sitting at around 30% over a long winter and the Fogstar lithiums were fine but I'd been paranoid the...
@StormyNomad already covered DVCC which is the obvious one, but something that tripped me up on my shepherd's hut build — make sure the VE.Can termination resistors are actually in place at both...
@PanelKate that's a good shout on the GX Touch — I ditched mine on the shepherd's hut build and just use VRM remotely now, makes a surprising difference.
One thing nobody's mentioned yet — check...
@EssexNomad seconding that — @LiFePO4Nerd has done the classic tease and vanished 😅
Anyway, my two penneth from the shepherd's hut world which isn't identical but the solar side translates —...
Got a shepherds hut setup myself so following this closely.
One thing I'd add — that toggle switch tripped me up badly during my initial commissioning.
