Anyone else noticed their electricity bill jump again this month?

Switched to a Fogstar Drift 48V setup last spring and honestly the smug satisfaction of watching everyone else's energy bills go up while mine goes down is carrying me through these dark winter months. 🔋

Octopus keep sending me emails about price cap changes and I just sit there cackling like some kind of battery-powered villain.

Seriously though, if you're still grid-dependent and feeling the squeeze, the maths on a decent LiFePO4 bank genuinely does start to pencil out when prices keep spiking like this — Victron kit isn't cheap upfront but the payback window shrinks every time the unit rate goes up, which apparently is just forever now.

Curious whether anyone here is on Agile tariff and actually arbitraging the overnight cheap rates into their batteries? That feels like the real endgame move — let the grid do the heavy lifting at 2am when electricity is basically free, then laugh at your neighbours during the peak rate evening hours.

Would love to see what setups people are running — particularly if anyone's gone big with a second-life EV battery bank. That rabbit hole has been haunting my browser history for weeks.

@MarineClare that smug satisfaction is absolutely real — I get it every time I check the Victron app and see how little grid I've pulled.

Curious though, how are you finding the Fogstar Drift over winter? I'm mid-build on a shepherd's hut setup and trying to decide between the Drift and a couple of Fogstar Evo units. Main concern is whether the capacity holds up when temperatures drop properly — we've had a few nights down near zero here and I'm not sure how much that's denting your usable capacity in practice.

Also what size array are you running with it? Shorter days have been my biggest worry for the hut since it's not a mobile setup like my van where I can chase the sun a bit.

@MarineClare know that feeling well — sat in the static last weekend with the wind absolutely battering Dartmoor, watching the battery bank hold steady at 94% and thinking this is why I did it.

The funny thing is I used to dread the dark months. Now it's almost perversely enjoyable tracking how the system handles the reduced solar and compensates with wind input. Every time a mate texts moaning about their direct debit going up again, there's a quiet satisfaction that's frankly indecent.

The upfront cost stings, no question — my Victron kit didn't come cheap — but I did the rough maths last month and I reckon I'm genuinely ahead of where I'd be on grid now, even accounting for the investment.

@EwanChapman the Victron app is dangerous though, isn't it — absolute rabbit hole at midnight.

@MarineClar same energy here — got my tiny house dialled in with a Victron Multiplus and Fogstar lithium bank, and honestly the standing charge is the only thing that still stings. Tempted to go full island mode just to dodge it entirely.

Dark mornings are rough for solar but I've got a small wind turbine picking up the slack through winter. Panels barely do anything before 10am but the battery's usually still got plenty from overnight wind.

Anyone else finding the standing charge more annoying than the unit rate at this point? Feels like you pay just for the privilege of being connected even when you're barely drawing anything.

Haha, this thread is giving me life. @MarineClare the Fogstar Drift is a brilliant choice — I went that route about 18 months ago and the payback calculation gets more satisfying every quarter when the bills land.

What's really got me grinning lately is that my neighbours have started asking questions. Had three separate conversations over the fence in November alone. Slowly converting the street one cup of tea at a time 😄

@StormyHiker those windy winter days are genuinely the best — watching the turbine or panels doing their thing while everyone else is dreading the direct debit ping.

Anyone else finding the cost of entry for new people is the main barrier right now? Lithium prices have come down but the upfront outlay still puts folk off. Worth having a sticky thread about realistic payback timescales maybe?

@MarineClare the timing of your switch is almost poetic — last spring felt like the turning point where the maths finally became undeniable for lithium setups.

My own story: I'd been running a cobbled-together lead-acid bank for years, watching it degrade every winter just when I needed it most. Switched to a 48V Fogstar lithium bank paired with a Victron Multiplus-II about 14 months ago specifically because emergency backup capacity terrified me with the old chemistry.

What's shifted my perspective this winter isn't just the bill — it's knowing that when the grid goes down at 2am in a Scottish storm, I've got genuine usable capacity rather than the top 50% of a sulphated lead bank pretending to be healthy.

The numbers are satisfying. The reliability is what actually matters.
