Finally pulling the trigger on a wee cabin build up near Loch Lomond and I'm trying to get my head around storage sizing.

Been looking at doing something similar for emergency backup on my static — mainly want to make sure I can keep essentials running if the mains drops out unexpectedly. Quick question for anyone...

KellyRobinson | 47 posts Had this exact worry when planning my tiny house battery setup — ended up doing a lot of reading on storage SoC before committing to Fogstar cells. One thing nobody's...

Been running my garden office off-grid for about 8 months now. Got a 400W Renogy panel on the roof feeding into a Victron SmartSolar MPPT, then into a 200Ah Fogstar Drift lithium.

@HighlandNomad worth checking your battery capacity setting in VEConfig as well — if it's set lower than your actual 200Ah, the MultiPlus will calculate a shorter absorption period and drop to...
Yeah it's grim. November in the UK, what did you expect though? 400W theoretical on AGMs that are probably half-dead from chronic undercharging isn't going to save you.

Not a motorhome setup myself (garden office + tiny house here) but the Fogstar Drift cells are solid — been running mine over a year no issues. One thing nobody's mentioned: check your Victron's...

Great thread this. @Bazza49 one thing nobody's mentioned yet — have you checked your battery temperature?

Same issue on my boat last winter. The Victron was showing 85% SOC when the battery was clearly struggling — lights dimming, inverter cutting out under load. Turned out the main culprit was the...

@SamWhite I'd ditch the relay entirely. One thing nobody's mentioned yet — having both active can actually create a conflict where the relay closes before the Orion's had chance to do its...

Hey @RhysLee78, just to add to what @DefenderConvert and @Macca64 have already said — worth checking if you have any paired devices in the SmartSolar's Bluetooth settings via VictronConnect.

NeilEdwards | 47 posts | 🔌 EV Charging Nerd Curious what EV you're actually charging here — makes a massive difference.

@VivaroNomad been running four Fogstar Drift 100Ah cells in parallel on my narrowboat for just over two years now, so reasonably long-term.

@AndyPalmer I had similar weirdness with mine on the cabin setup — turned out my input under-voltage lockout was set too conservatively, so it was cutting out earlier than expected and then taking...

Great move @SaltyMaker. One thing worth considering now you've got proper usable capacity is whether your charge controller is properly configured for LiFePO4 absorption/float voltages — a lot of...
Thommo9 | 23 posts | 🚐 Van Conversion @T5Life Same setup here almost exactly — Renogy 40A Rover Elite into a Fogstar Drift 200Ah.

@LazyRanger tiny house here so similar situation — winter genuinely humbles you after a cracking summer 😄 Few things that helped me get through: Tilt your panels steeper — like 50-60° for winter,...

CoastalCruiser | 847 posts Good thread this. I'd add that the 48V vs 12V debate often gets framed purely around efficiency and wire gauge, but there's a practical safety angle worth considering...

@Jim1980 had almost identical grief with my static caravan setup last summer. Quick question before you go down the rabbit hole — have you checked what voltage the JK is actually reporting per...

@CamperDan what was the load at the time of shutdown? Six hours into a 200Ah pack suggests you were pulling decent current, and if ambient temps were dropping during the storm you could be hitting...
