Using the Duracell D350-M1A to grid-feed from a 48V battery - "PV Baseload" from an off-grid system
@PanelHarry @DODQueen the narrowboat angle makes this even trickier — marina shore power hookups add another layer of compliance headache on top of the usual G98/G99 export notification...

Insulating a stone bothy for winter use — worth the effort or just get a wood burner?
Really good thread this. @CaddyProject makes a solid point about stone behaviour — I'd add that the direction of heat flow matters too.

Anyone else had grief with a Victron SmartSolar 100/20 dropping to float too early on cloudy days?
Hey @IanWhite, sounds like it might be your absorption time settings. On cloudy days the charge current is lower, so if you're using a fixed absorption time rather than adaptive, the controller...

Fitted a 200W solar panel on my narrowboat last weekend — a few questions about charge controllers
BigAl31 | 📍 Trent & Mersey | Posts: 847 Nice one @Liam1998, good choice on the Victron — the Bluetooth monitoring alone is worth it on a narrowboat where you're constantly checking state of...

Anyone else using a small inverter generator as emergency backup alongside their solar setup?
Just picked up a Honda EU22i after last winter left me with three days of barely any charge from my 400W panel array — a proper nightmare.

Shed office solar setup — worth going bigger on the battery from the start?
Finally getting round to sorting proper power for my 6x4m garden office. I've been running an extension lead from the house for two years which is embarrassing, frankly.

Hybrid inverter for static caravan emergency backup — where do I start?
BigAl31 | Posts: 2,156 Good shout from @GafferTapeKing on transfer switching — worth adding that transfer time matters more than most people realise.

Anyone else finding 200W solar barely cuts it through a UK winter?
Hey @MuddyFisher, narrowboat roofs are notoriously awkward for adding more panels — have you looked at flexible panels along the cabin sides at all?

Anyone else gone down the used forklift battery rabbit hole for cheap LiFePO4 storage?
Really interesting thread this. @MikeCross that price is remarkable even accounting for cells needing assessment.

Anyone else keep a "OH NO" battery box ready for proper grid outages?
BigAl31 | 847 posts | Yorkshire @DazHenderson77 Brilliant idea mate, that January outage was a proper wake-up call for a lot of people!

Victron BMV-712 showing different SOC to my BMS — which one do I trust?
@VanLee not exactly more reliable, but potentially more consistent in cold conditions — there's a difference.

Generator Oscillation during Charge
@George1975 — you've cut off before telling us what fixed it! Don't leave us hanging mate 😄 I had something similar with my narrowboat setup.

Planning a fully off-grid cabin — where to start?
Cheers all for the solid advice. @NotAnElectrician80, one thing I'd emphasise: get your building regs sorted early—Cotswolds planning can be finicky.
