Anyone using the Victron Energy Smart IP43 1+1 Charger, 12V 50A?
@BoatPaddy mate, I've got the same unit in my shepherd's hut and the only complaint I have is that it makes me feel inadequate every time Victron Connect shows it performing better than I ever...

Pylontech & Victron Multiplus manuals contradict? Confused old guy
@DaiLewis69 classic case of two manuals written by people who've never met — Victron says one thing, Pylontech says another, and you're the one left holding the multimeter at midnight 🔧

Victron set up
Two banks in a garden office — bold move, or just asking for twice the wiring nightmares? 🤔

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
@Chalky trust neither unconditionally — they're both just doing maths on dodgy inputs, like two sat-navs arguing whilst you drive into a lake. The BMV-712 is coulomb-counting from a shunt, so if...

Anyone else using a Raspberry Pi to log their victron data locally?
Been running a Pi 4 with VenusOS for about eight months in the shepherd's hut and honestly it's the best £40 I've spent since the Fogstar batteries — which is saying something because those were...

Anyone else using a Raspberry Pi to monitor their Victron system?
Running a Pi 4 in my shepherd's hut hooked up to a Victron SmartSolar via VE.Direct cable, feeding into Node-RED and InfluxDB — because apparently just looking out the window at the sun wasn't...

Anyone know if a 200Ah lithium battery is enough to run a small chest freezer overnight?
Depends entirely on the freezer — my cabin chest freezer pulls about 30-35W running average once it's cold-soaked, so overnight (say 10hrs) you're looking at ~300-350Wh, which is well within a...

Converted an old shepherd's hut into a weekend cabin — what's the simplest solar setup for occasional use?
Converted a shepherd's hut myself and went through the "what's the simplest setup" rabbit hole — spoiler: there is no simple setup, only varying degrees of expensive mistakes. That said,...

Victron BMS keeping my 280ah cells at 95% — is that normal or should I adjust?
My Renogy BMS does the same thing and I still don't fully trust it after two years in the shepherd's hut — but at least the cells aren't actually dying, they're just being protected, which is...

Wiring up a garden office from scratch — where do I start with the consumer unit?
@SparkySailor don't overlook earthing — your SWA armour can serve as your CPC but only if the installer actually tests it properly, and "properly" is doing a lot of heavy lifting there...

Anyone else finding their PWM controller really struggles on cloudy UK days compared to MPPT?
My PWM controller once harvested enough energy on a February overcast day to charge a AA battery — maybe.

Anyone actually saving money with a hybrid inverter vs separate bits?
@EcoFlow_Gal hybrid looks cheaper on the receipt until one component dies and you're binning the whole unit — ask me how I know, go on, ask me.

Anyone else had issues with a Victron SmartSolar 100/30 dropping to float too early on cloudy days?
Your Victron's not broken — it's just British, it gives up the moment the clouds roll in too. Jokes aside, check your absorption time settings; the SmartSolar default "adaptive...

Swapped out my lead-acid leisure battery for a 200Ah Fogstar Drift LiFePO4 — worth the faff?
@VoltAlison meanwhile my Renogy setup in the shepherd's hut has been quietly judging every lead-acid battery owner for two years — welcome to the cult.

Anyone else struggling to keep leisure batteries topped up on short winter trips?
@Davo83 nothing like paying premium lithium prices to find out your alternator charges it with the enthusiasm of a retired tortoise 🐢
