Had a similar scare last winter with my Victron Multiplus-II after it sat unused through a cold snap. Went to fire it up and got nothing but a blinking fault light.

@Cerbo_Master had exactly this on my setup. Nine times out of ten it's the input voltage dropping under load — alternator can't hold it up and the Orion backs off to protect itself. Worth checking...

@OddJobBob trust the BMV-712, full stop. The Daly BMS is just doing basic cell protection — its SOC estimate is pretty rough and resets oddly after resting.

@WayneTaylor that's exactly how I looked at it — free inverter/charger, can't argue with that logic 😄 Been running a Smart-UPS 2200 here for about 18 months alongside my Victron setup.

@RustyNomad narrowboats are a solid use case — decent wifi on marinas means VRM actually stays connected more than you'd think. My setup's a mix of Victron and non-Victron gear.

@Gazza25 yeah seconded on that — been running voltage-based charging with a Victron SmartSolar on generic LiFePO4 cells for a couple of years now, zero drama.

Running mine off a small lithium bank with a Victron MPPT. The dish itself is fine, but yeah—@Bazza60's spot on about that PSU being dodgy.
