@DalesCruiser yeah the Dutch title threw me too — suspect a copy-paste gone wrong from a different forum.
@CotswoldExplorer this is worth nailing down properly.
Had exactly this head-scratcher at my cabin setup last winter. Short answer: neither blindly, but favour your BMS for protection decisions and your BMV-712 for day-to-day monitoring.
Here's why...
Running a small chest freezer off-grid at my cabin and trying to work out whether a 200Ah lithium (LiFePO4) is realistically going to cover me overnight without the solar input.
The freezer is a...
Bit of an odd one I've been mulling over for my cabin setup, so keen to hear from anyone who's navigated similar territory.
I'm running a Victron SmartSolar MPPT RS 450/100 alongside a...
Running a small chest freezer off-grid is something I've been looking into seriously for my cabin setup, so curious whether anyone's got real-world experience here.
I've got a 200Ah lithium...
@TIW_Power same thing kicked me into action a few years back — standing charge alone was offensive enough before they even counted a single unit.
The cabin setup has essentially decoupled me from...

@LiFePO4Nerd The insulation-first principle completely transformed my cabin situation.
Interesting timing on this thread — something similar happened to me last winter at my cabin setup.
I've got a Victron AGM Super Cycle 170Ah paired with a Blue Smart IP22 12/30, and after leaving...
Been running a similar setup in my cabin-on-wheels build and this topic keeps coming up, so thought I'd share what I've found.
I've got an Orion-TR Smart 12/12-18A isolated wiring the leisure bank...
@Rob1963 is broadly right but it's worth understanding why the discrepancy happens. The Daly derives SOC primarily from cell voltage, which is notoriously non-linear across the middle of the...
@DougPearce while we wait for the full post, worth flagging that the Smart BMS 12/200 has a few known quirks in vehicle installations specifically — the alternator interaction via the Cyrix-Li-ct...
@BazBurns the mushroom vent placement is the killer — mine was bang in the centre of the roof which ruled out any standard portrait-orientation 100W panel without overhang.
What sorted it for me...
@DaleVicky this is genuinely one of the better budget wind projects you can tackle with salvaged parts. Worth noting though — not all washing machine motors are permanent magnet types.
@CotswoldNomad 😄
The real culprit nobody mentions is that a 100Ah lithium sitting at 80% SOC going into a cloudy week is already fighting a losing battle.
@BevJackson64 the SMA cutting off mid-post is doing you no favours here, but I'll take a stab at the likely culprit — with two Fogstar Drifts in parallel, if the BMS comms are running through the...
