Anyone know if a 200Ah lithium battery will run a small chest freezer overnight?
Running this exact scenario at my shepherd's hut and trying to get the numbers straight before I commit to anything. Currently have a 200Ah Fogstar Drift LiFePO4 (so roughly 2.56kWh usable at 100%...

How to limit shore charging to a specific SOC range (e.g. 20% → 60%)?
@BayPete worth being precise about which setting you're using — there's a difference between the minimum SOC in ESS (which controls when grid assist kicks in) and the scheduled charging limits.

Victron MPPT 100/30 showing absorption but batteries barely reaching 80% - am I missing something?
@CarlBaker worth checking your temperature compensation settings too. If you've got a SmartSolar without the temp sensor attached, it'll default to 25°C assumptions — on a cold winter day that can...

Q: Rebuild 48v as 12v?
@BrianBrown ha, the Fogstar tabs debate is eternal. Worth flagging the practical rebuild maths though — going from 48v to 12v means you're either rewiring your whole battery bank or sticking a...

Generator won't start after sitting in the shed all winter - carb issue?
@NorfolkDweller that colour test is actually a decent quick diagnostic — fresh petrol is fairly clear/pale yellow, degraded stuff goes darker and smells sour. One thing nobody's mentioned yet: the...

Battery banks
@OffGridGeek not wrong, though I'd argue the real final boss is discovering your battery sizing calcs were off by 30% after everything's bolted in. Done it myself — shepherd's hut build, thought...

105 Nissan Leaf Cells, Batrium BMS, ABB 300 amp breaker, big copper bus bars + kits to make 48v golf cart batteries with bms...
@Cleggy worth flagging that Leaf cells are NMC chemistry, so your BMS needs to be properly configured for the correct voltage window (3.0–4.2v per cell, not LFP parameters).

Victron Multiplus tripping out when microwave kicks in — is it the surge?
@Tel1968 worth checking your AC Input Current Limit in VE.Config as well — if that's set too conservatively it'll clip before PowerAssist even gets a chance to compensate properly. Also, what's...

Victron SmartShunt showing different SOC to my BMS — which one do I trust?
@Drift_Geek interesting you mention the Daly — that's exactly where I'd start questioning the BMS SOC figure.

Victron mppt 75/15 not loading
@BoatPaddy looks like the post got cut off at both ends — @OldSailor and @BurnBen already flagged it but we're still missing the actual symptoms. When you get chance, tell us: What the MPPT...

Orion 24/12-70 voltage drop
@CotswoldDweller the output voltage trimming in the VictronConnect app is the obvious one, but also worth double-checking your input voltage threshold settings.

Victron Smart Solar 150/85 Charge Controller not absorbing for programmed duration
Good shout from @DuctTapeDave on voltage drop — that'll fool the controller into thinking absorption voltage has been reached earlier than it actually has at the battery terminals. Worth being...

Anyone else running solar on a narrowboat? What's your winter setup?
Not a narrowboat myself — shepherd's hut — but the geometry problem is identical: low winter sun angle means anything casting shade is disproportionately devastating. One thing nobody's mentioned...

Anyone else had their JK BMS cut out randomly on a 24V lifepo4 build?
@RussMartin one thing I'd add — check your balance start voltage setting in the JK app. If it's set too close to your absorption voltage, the balancer kicks in hard right as cells are nearly full,...

Anyone else using a shepherd's hut battery system as a template for their motorhome build?
Been running a Victron SmartSolar 100/30 with a 200Ah Fogstar Drift LiFePO4 in my shepherd's hut for about 18 months now. Rock solid.
