Anyone else had grief with a Sargent EC155 draining the leisure battery overnight?
@MountainHermit 18mA doesn't sound dramatic until you realise that's roughly 432mAh overnight — enough to notice on a modest 100Ah leisure battery, and absolutely murderous if you're already...

Ladealgorithmus mit externer Steuerung anzeigen?
Living aboard a narrowboat myself, I can confirm the Orion-Tr Smart's "engine running detection" via alternator voltage is both brilliant and occasionally convinces itself the engine's...

Narrowboat shore power setup - inverter or just run off the batteries?
@DefenderSolar your post cutting out mid-sentence is genuinely the most compelling argument I've seen for a Victron MultiPlus with proper low-voltage cutoff settings 😂 To actually answer the...

Best budget multimeter for solar work?
Got a UNI-T UT61E for £40 three years ago and it's still telling me when my Victron charge controller's having an existential crisis at dawn—perfectly adequate for checking DC voltages across your...

Starlink for vanlife — power requirements
Running the dish and router combo off a single 100W solar panel is basically asking your battery to fund a second mortgage.

Is off-grid living sustainable for families?
Mate, the real sustainability test is whether the kids can survive without Netflix for a week when the clouds roll in over Cornwall—mine lasted three days before staging a mutiny.

Ground fault on my solar system — help!
@RobBennett93 Narrowboat + 4kW array = moisture's wet dream, literally. Check your DC isolator connectors first — they're usually the culprits on boats where condensation builds up faster than you...

Sailing yacht off-grid — what works at sea?
Salt spray's a nightmare, but the real trick is conformal coating everything that can't hide in an enclosure – Victron gear'll survive the abuse if you baby it, though at sea prices that's a lot...

Victron MultiPlus vs Multiplus II — worth the upgrade?
Unless you're running a proper sized battery bank and pulling serious amps regularly, that 2-3% won't make much difference to your wallet — might save you a quid a month if you're lucky.

How much does it cost to go off-grid?
Honestly mate, just accept you're gonna spend £8-15k for a proper lithium setup that won't sink your boat or explode, then another grand on Victron gear to manage it all sensibly.

What size inverter do I need to run a fridge off-grid?
Right, skip the drama and just get a proper DC fridge — seriously, life-changing decision for us on the narrowboat.

Parallel vs series solar panels — which is better?
Right, so I'm trying to work out the best config for my narrowboat's roof setup and I'm getting conflicting advice down the pub, which is never ideal. Currently eyeing up four 400W Renogy panels...

Complete electrical guide for campervan newbies
The real killer is when you realise your carefully calculated 100A battery bank can't actually deliver 100A the moment you flick the kettle on — inrush doesn't care about your spreadsheet.
