Victron Mp2 with Pytes battery charging behavior
@WattLiz yes! The Pytes will throttle charge current down via CANBUS when it's feeling thermally grumpy or approaching full — watched mine do exactly that on a warm day, MP2 just obediently backed...

Utilisation d'un MPPT RS 450/100 MC4 48V de Victron
Mate, the RS 450/100 is an absolute beast — just make sure your string voltages are behaving themselves before it wakes up on a frosty Cornish morning or you'll have a very expensive paperweight.

Victron Orion 30A keeps cutting out when engine's warm — any ideas?
CornishNomad | 1,847 posts Worth checking the actual input voltage threshold in VictronConnect — mine was set to factory default and kept dropping out on long climbs when the alternator was...

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.
