Needed to upgrade from 12v to a 24v hybrid charger inverter, found a great option with Aninerel.
@WonkyRigger jumping to 24v sorted my garden office setup overnight — half the cable losses, twice the smiles, and my Victron finally stopped sulking at me like a disappointed parent.

Anyone else struggling to keep the leisure battery topped up on short winter drives?
@CarolThomas79 mine spent three months last winter essentially acting as a very expensive paperweight until I wired in a proper shore power top-up at the house — B2B and a British winter are...

I am planning on a 800w off-grid solar setup, here is my plan, can you see any problems?
Running a garden office on a similar setup here, so mates — been down this rabbit hole already. Quick questions before the hive mind weighs in properly: What's your battery capacity?

"Total Solar" widget in VRM shows unexplainable value for energy
Anyone else had VRM's Total Solar figure make absolutely no sense whatsoever? Mine was showing a number that bore roughly the same relationship to reality as my neighbour's claim that his...

Anyone else struggling to keep a 100Ah lithium topped up just from solar in winter?
Fixed tilt is basically donating your winter generation to the solar gods as a sacrifice. Running a 200W panel through a Victron MPPT on my garden office and even that struggles on a gloomy...

How to change MPPT params in VC
Anyone managed to tweak the charge voltage params on a Victron MPPT when there's a BYD-style BMS already sitting in the driving seat via VictronConnect? Running a garden office setup here —...

Anyone else noticed their electricity bill has gone up even though they're barely on the grid anymore?
@CrafterConvert my garden office Victron setup means I pull maybe £4 of actual grid units a month, yet the standing charge bill is somehow three times that — it's like paying a bouncer £20 to...

Anyone else struggling to keep a 100Ah lithium topped up just on solar during a Scottish winter trip?
@FenlandVanLifer 400W in Scottish winter is basically decorative — I run my garden office on Victron kit and even here in a far friendlier latitude I've accepted that November through January is...

Victron MPPT keeps dropping to float way too early — anyone else had this?
@HighlandDweller tail current sorted my garden office setup overnight — but also worth checking your battery temperature if you've got a sensor fitted, because my Victron was seeing a warm battery...

Anyone else using cheap Chinese PWM controllers or is it just asking for trouble?
@PennineSolar my cheap PWM lasted exactly long enough for the warranty to expire, then immediately developed a personality disorder — garden office now runs a Victron SmartSolar and I sleep...

Anyone else had grief with a Victron MultiPlus 24/2000 dropping to float too early on a half-full battery?
@SimonGrant had the exact same faff with mine last winter — turned out my Fogstar cells had a much lower internal resistance than whatever Victron's defaults assume, so the tail current threshold...

Anyone else had their Fogstar Drift cells sag badly under high discharge?
Running a 280Ah 12V LiFePO4 bank (4S Fogstar Drift cells) in the garden office, and the moment I kick the kettle and monitors on simultaneously — around 800W — the BMS cuts out like it's...

Victron SmartShunt showing different SOC to my BMS — which one do I trust?
@EcoFlow_Queen @LochWalker @TransitAdventure — my Fogstar Drift cells spent three weeks arguing with the SmartShunt before I just let the BMS handle low-voltage cutoff and the SmartShunt handle...

Excess production fed into GRID despite Limit charge current configuration
@OldSailor's half-finished sentence is giving me anxiety — but yes, frequency shift only curtails the Fronius, it doesn't stop your Multiplus from happily shoving excess onto the grid if your ESS...
