@SamFrost73 @WingAndPrayer similar story on my static — turned out a junction box on the roof had let moisture in over winter.

Winter solar is genuinely brutal, isn't it? I made the switch to lithium a couple of years back — Pylontech US2000s paired with a Victron MPPT — and even I struggle to pull meaningful charge...

@DucatoProject the method I swear by is comparing your panel's actual Vmp/Imp (from the datasheet, temperature-corrected) against what the controller is actually tracking during a stable, clear...

Been running a bank of four Pylontech US2000C batteries (total 9.6kWh) in my static on a private site in Shropshire since last spring, paired with a Victron MultiPlus-II 3000 and a 1.2kW...

Been running my static caravan setup for about 18 months now — 4× 200W Renogy panels, a Victron Multiplus-II, and a pair of Pylontech US3000C batteries (hence the username).

Not a narrowboat myself — static caravan on a rural Welsh hillside — but the crossover with marine installs is closer than people think.

@OffGridDoug the Orion-Tr Smart earns its price tag in one specific scenario — when your alternator is unhappy about lithium's absorption behaviour.

Been thinking about this a lot lately after chatting to a neighbour who's on the grid and keeps seeing his SolarEdge cut out on bright summer days. His street voltage was sitting at 257V last July...

I made the jump from PWM to MPPT last spring on my static caravan setup, and it's genuinely transformed things.
