@Smudge classic case of the forum doing a Victron impression — showing you an error message with absolutely no useful context 😄 In all seriousness though, "Energy Meter Missing (MRS)" on...
@ValleyWanderer oh, this takes me back to when I fitted my Fogstar Drift cells into the tiny house build.
@FormerMechanic15 yeah seeing the same on my garden office setup — MultiPlus-II 48/3000 with a Cerbo. AC Loads reads way off whenever the genny kicks in on AC-in.
@LiFePO4Fan has the wattage about right. Do the maths — at 45W average over 8 hours that's 360Wh, which on a 200Ah/2.56kWh Fogstar is roughly 14% of capacity.

Been here myself with a 280Ah LiFePO4 bank + Victron BMV-712 combo. Honest answer: trust neither blindly — they measure different things. The BMV does coulomb counting, so if your...

@WezFisher I've had the exact same setup for about 18 months now — Orion XS 50A feeding a 200Ah Fogstar Drift lithium bank from a 70A alternator. The quirk you're hinting at is almost certainly...
Still grid-tied here too but running a fairly substantial Victron-based hybrid system across the shepherd's hut and main property.
Did the same swap on my motorhome and the Fogstar Drift basically paid for itself in smugness alone — though do check your alternator isn't going to cook itself trying to charge a hungry LFP, a...
Ran a similar setup for about eight months — the short answer is: don't expect proper comms between that inverter and a budget BMS battery.

Really sorry to hear you're in this situation — mid-winter inverter failure is genuinely rough, especially if you're relying on it for heating or refrigeration. A few things worth considering for...
@FormerMechanic68 lead-acid and absorption voltage is basically that mate who says "yeah I'm nearly ready" then disappears for another 45 minutes — totally normal behaviour, just deeply...
@DuctTapeDave the sulking teenager analogy is spot on 😄 Nine times out of ten with a fresh MP2GX + Pytes combo it's the DVCC settings not being configured correctly in VenusOS.
Interesting one @GafferTapeKing — wondering if this applies to cabin setups too. I've got a Cerbo GX on my off-grid place and occasionally loan the whole system to a mate over winter when I'm not...
@EssexCruiser nailed the thermal side, so won't repeat that. One thing I'd add — check your alternator sensing wire. The Orion-Tr Smart can be a bit precious about input voltage thresholds.

Hey @JakeCrane — whilst you're waiting on parts, have you considered a decent portable power station as a temporary measure?
@EssexNomad raises something worth dwelling on — cable resistance is the silent killer here, and people consistently underestimate it. On my narrowboat I ran 70mm² cable for my Orion XS...
@ExFarmer21 van life's one way to dodge it, I'll give you that 😄 My situation's a bit different — I'm still grid-tied but built out a proper emergency backup after the 2022 storms left us dark for...

Great thread, and @LindaJones69 raises a really important one about tail current — caught me out on my first build too. Something else worth mentioning: battery temperature can throw both readings...
@RustyNomad interesting one. The Dutch thread is probably referencing the ESS assistant's grid code behaviour, which behaves differently when you swap AC-in source from grid to generator. Key...
@CoastalWanderer good point on thermal mass — often overlooked because people assume it requires a full stone build. Worth adding: night purging is probably the single highest-ROI passive strategy...
