Anyone know if a 200Ah lithium battery is enough to run a small chest freezer overnight?
Good points already made, but nobody's mentioned DoD limits yet. With LiFePO4 you can draw down to 80% DoD comfortably, so your usable capacity from a 200Ah pack is realistically 160Ah.

Batterie plomb tension qui baisse sur MPPT 75/15
Seen a few threads lately about dodgy voltage behaviour on lead-acid setups and thought I'd share something from my own experience, because it catches a lot of people out. Running a Victron...

VRM dashboard: DC sources drawn as a chain, and an "Off" inverter block with no inverter
Seeing some odd behaviour on my VRM dashboard that I suspect others with DC-only setups might be running into. Running a Cerbo GX on Venus OS v3.80 with no inverter — purely DC system with a...

Anyone else using a Raspberry Pi to log their Victron data locally?
@DazHenderson77 worth noting that if you're pulling MQTT from the Cerbo, you can subscribe to the N/<VRM-ID>/battery/+/Dc/0/Voltage topic tree and get cell-level data out of a...

Anyone else using old washing machine motors for a DIY wind turbine or is it just me?
@IslandOffGrid the stator lamination quality on those pancake motors is genuinely decent for a freebie — the main issue I kept running into when I rewound a Samsung DD unit was matching the new...

Bit of a familiar-sounding situation here — wanted to share my own experience because I've seen this pattern crop up a few times with rack-mount LiFePO4 systems. When I first commissioned my setup...

Anyone else using a Raspberry Pi to log their Victron data locally?
@ExJoiner19 Worth noting that if you're pulling data from multiple Victron devices simultaneously, the VE.Direct USB adapters can occasionally cause USB enumeration headaches on the Pi —...

Anyone else noticed their Victron MPPT behaving oddly in winter sun angles?
@OffGridDoug worth checking your panel voltage at low sun angles — winter sun sits so low here in the UK that your series string can actually undershoot the MPPT's minimum operating voltage if...

Anyone else had issues with Daly BMS cutting out under high discharge loads?
@CamperDan the overcurrent trip on Daly units is notoriously sensitive to inrush current rather than sustained draw.

Anyone else running reconditioned forklift cells on the cheap? Share your BMS setups
I've been running a 280Ah bank of reconditioned 3.2V LiFePO4 forklift cells for about 18 months now — picked up eight of them from a local industrial supplier for £180 the lot.

Anyone else using a small inverter generator as emergency backup alongside their solar setup?
@DebbieEvans January is exactly where solar-only setups fall apart — I've got a 48V LiFePO4 bank (Fogstar cells, 280Ah) paired with a 600W array and even that struggles mid-winter with three...

How to size your battery bank for off-grid
@BoatMark nailed it — winter's the real test. I've got 15kWh usable across my setup and still budget conservatively December through February. The chocolate teapot analogy's spot on.
