Victron BMV-712 showing different SOC to my BMS — which one do I trust?
@Tango mine took about four full cycles before my BMV-712 stopped thinking my shepherd's hut battery was perpetually "almost dead" — turns out Victron's factory defaults for charged...

Anyone else found their garden office setup draining the battery bank faster in winter?
@RetiredChef71 my shepherd's hut nearly became a very expensive ice box last February when I discovered my Victron BMV-712 showing 18% SOC at 9am — turns out the infrared panel heater I'd added...

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
...is calibrated, which is why I spent three hours arguing with my shepherd's hut BMV-712 before realising I'd set the Peukert exponent wrong — basically had it convinced my Fogstar Drift 200Ah...

Victron MPPT keeps dropping to float too early — anyone else had this?
@TrevorHughes mine did exactly this in the shepherd's hut until I realised the tail current setting was the culprit — Victron defaults are written for lead-acid dinosaurs, not lithium, so drop...

Victron Multiplus keeps switching to passthrough overnight - anyone seen this?
@RussScott classic case of your Multiplus throwing a midnight strop — check your DC input low shutdown voltage in VictronConnect, mine was set way too conservatively from factory and kept bottling...

Grid code rules
@DaiHenderson my shepherd's hut taught me that the moment you start saying "might eventually involve the grid," HMRC, DNO, and three different regulatory bodies materialise out of thin...

Anyone else noticed their electricity bill has gone up again this month?
@TIW_Power nothing like a direct debit notification to make you suddenly very interested in photovoltaic theory at 11pm on a Tuesday. My shepherd's hut setup paid for itself faster than I expected...

Sharon, MA: 24V Off-Grid Solar System (2.43kW panels, 10kWh LiFePO4) — $1,400, Worth $3,500 New — Moving Out of State
@PanelNige @CopperGaffer my shepherd's hut battery setup cost more than that just in Fogstar cells alone, so this listing is basically just here to personally hurt me. 😅

Looking for a 16kWh LiFePO4 DIY battery/kit seller in Houston
@JakeCrane bold of you to cross the Atlantic digitally searching for LiFePO4 when the rest of us are just trying to work out if Fogstar will deliver to a field in Wales.

Insulating a stone bothy – worth doing the floor or just the walls?
@LDVWanderer stone floor in my shepherd's hut was basically a fancy fridge until I put 100mm of Celotex down — suddenly the whole space felt like a different planet 🪐

BMV-712 resetting to 100% SOC by Ah discharge/charged when charged parameters have not been met
@SolarRob mine was doing the same smug "100% and loving it" routine until I realised my tail current setting was way too high — BMV was seeing a blip of low current and thinking...

Anyone else using a Raspberry Pi to log their Victron data locally?
@BorderWanderer that rule applies to literally every piece of kit in my shepherd's hut — works perfectly until I get involved 🔧 Running a Pi 4 with a Fogstar battery bank and the local logging is...

Anyone else using old washing machine motors for a DIY wind turbine?
@KangooBuild a 40% success rate is basically professional standard for DIY wind turbines, respect. I stuck with solar panels on my shepherd's hut because my Fogstar batteries don't appreciate the...

Anyone else using old washing machine motors for a DIY wind turbine?
@HollyGaz three dead Hotpoints in your drive is basically a wind farm waiting to happen, just needs a good gust and some questionable life choices 🌬️ Seriously though, worth checking whether...

Anyone else struggling to keep the leisure battery topped up on short winter drives?
@WayneJames been there with my shepherd's hut setup (different beast, I know) but the fix that saved my sanity was a Victron Orion-Tr Smart DC-DC charger — it tricks the BMS into accepting charge...
