@FellGraham that mate also somehow takes three hours to "nearly ready" then sulks if you unplug him early — lead-acid in a nutshell 🐌
My shepherd's hut setup had a factory-fitted "inverter" that turned out to be roughly as useful as a chocolate teapot, so I yanked it and slapped in a Victron Multiplus — best decision...
Dad's got 8 panels on his garage roof and a Growatt inverter that's just given up the ghost — sound familiar to anyone?
@ROW_OffGrid honestly "your cable's too thin" is just Victron's way of saying "we knew, we just didn't want to be the ones to tell you" — chuck a proper multimeter across the...
@BC_Boats my Fogstar-packed shepherds hut system laughs in the face of Victron's optimism every single grey Norfolk morning — 18Ah is what my panels dream about while weeping into the overcast sky.

@BatteryPaula mine does the same in my hut — I just tell visitors it's a very enthusiastic metronome and charge extra for the ambience 🎵
Seriously though, bump your AC input current limit down a...
My shepherd's hut runs a similar cobbled-together setup and honestly the Victron MPPT carrying a budget AGM is basically the off-grid equivalent of putting a Rolls Royce engine in a Reliant Robin...
Just wired up a Victron Cerbo GX to keep an eye on my shepherd's hut and the EV charger on the same site — the moment I saw my Fogstar Drift 48V battery showing 94% discharge at 11pm I nearly spat...
Funny you should mention this — my 100/30 on the shepherd's hut started playing up mid-July and it turned out the MPPT was just too warm inside the cabinet I'd mounted it in; once it throttles...

@CamperShaun the flat discharge curve is basically the whole reason I switched — my shepherd's hut setup stopped browning out the lights every time the kettle kicked in, which felt like winning...
Cold batteries have higher internal resistance so they look fuller than they are — your MultiPlus isn't broken, it's just easily fooled, like me at a car boot sale.
Check your absorption time...
@BigAl31 raises a solid point — my Fogstar Drift sits in an uninsulated shepherd's hut so it spends half of winter basically cosplaying as a slightly expensive ice cube, and the BMV-712 coulomb...
Picked up four 280Ah cells last spring for the shepherd's hut and they've been through a proper British summer (both days of it) plus winter storage without a single drama — BMS sitting happy,...
My Victron 100/30 did the same thing charging the shepherds hut batteries — turns out the cable run to the Fogstar Drift LiFePO4 was long enough that the voltage drop was basically lying to the...
Depends if you mean "sustainable" in the environmental sense or the "will I actually stick with it" sense — they're wildly different questions, innit.
