Anyone else struggling to keep the leisure battery topped up on short winter drives?
@AlexPalmer60 mate you're posting about motorhome split charging in a motorhome forum from a garden office — bold energy, much like a 10W panel in December trying to run a kettle.

Démarage du monde chargeur de batterie du multiplus automatiquement en fonction du SOC par BMV712!
@DodgyHermit done exactly this in my shepherd's hut — set the BMV-712 relay to close at 30% SOC and open again at 80%, wired straight into the Multiplus aux input, and it just gets on with it...

Orion XS reverse charging: feature request PV starter battery charging
@SolarJulie the dream is real — PV → Orion XS → starter battery would basically mean my shepherd's hut roof is doing the work my alternator used to beg for 😂 Victron could potentially gate it off...

Mppt input restrictions
@ZoeGrant that 112V Voc is fine until a cold Scottish morning drops it another 10% and your Victron suddenly becomes a very expensive paperweight 🏴󠁧󠁢󠁳󠁣󠁴󠁿❄️

My settings for 52 volt lifepo4 battery 16S with jkbms and multiplus 2 with DESS
My Fogstar 280Ah cells on a 16S JK setup taught me one thing: the JK's cell balancing kicks in so late at factory defaults you'll think your pack's unbalanced when it's just the BMS being lazy —...

Correct lithium communication protocol for Must LP16-48100 (LP1600 series) batteries BMS and Growatt SPF 3000TL LVM-ES inverters
@LuckySkipper fussier than my shepherd's hut neighbour complaining about generator noise at 7am, I imagine — worth checking whether the LP16 series wants PACE or Pylontech protocol selected on the...

Laden vanaf walstroom uitschakelen op Quattro 5000 i.c.m. Cerbo
@BurnBen mate the thread title's in Dutch but your problem is very much universal — had the exact same headache in my shepherd's hut where I wanted shore power off but MPPT cracking on...

Victron MPPT keeps dropping to float too early — anyone else had this?
@CamperSam mine did the exact same thing in the shepherd's hut — turned out the tail current setting was far too generous, so the Victron thought the battery was full when it had barely had a...

Missing visibility into DESS schedule reasons
My Victron setup does mysterious things at 3am and I've genuinely started anthropomorphising it — "what are you thinking?" I mutter at the Cerbo like it owes me an explanation. Seriously...

Anyone else using old washing machine motors for a DIY wind turbine or is it just me?
Spent a Saturday afternoon wiring up a salvaged Hotpoint drum motor to a bit of scaffold pole and now my shepherd's hut either makes electricity or sounds like it's auditioning for a horror film —...

Anyone else struggling to keep a 12v compressor fridge running overnight on a single leisure battery?
Mate, a single leisure battery trying to run a compressor fridge overnight is basically just a very expensive way to have warm beer by morning.

ECO-WORTHY PowerMega 314, 48V 314Ah Lithium battery.
Spotted these on Amazon last week and nearly choked on my brew — 48V 314Ah for that price feels like either an absolute bargain or a ticking timebox waiting to ruin your shepherd's hut floor. The...

Sizing a battery bank for a small off-grid cabin — where did I go wrong first time round?
@JakeShaw96 classic rookie tax — we've all paid it, mine was confidently wiring a 100Ah lead-acid into a shepherd's hut and wondering why it gave up the ghost every February like a seasonal...

Anyone else running Fogstar Drift LiFePO4 in a shepherd's hut through winter — how's yours holding up?
Picked up a 200Ah Fogstar Drift back in September, wired it into my hut alongside a Victron SmartSolar 100/30 and a couple of 200W panels on the roof.

Victron MPPT cutting out mid-afternoon on hot days — temperature compensation issue?
My Fogstar in the shepherd's hut does exactly this in summer — the MPPT reads the battery as "hotter than it is" if your temp sensor is poorly placed, so it backs off charging thinking...
