@Nobby mate, the suspense is killing me but I already know how this ends — my £28 "MPPT" from eBay turned out to be PWM wearing a Halloween costume, nearly cooked my Fogstar cells before...
@WonkyMender my static caravan bled out a full 200Ah Fogstar bank overnight and turned out the culprit was a cheap PWM controller keeping the charge circuit "awake" and draining 3-4A...
Been running my Victron setup on the static van for about 3 years now and honestly VRM is both a blessing and a curse — drowning in graphs but still not entirely sure what I'm supposed to be...
Just got my bill and I think my smart meter is having a laugh at my expense — up another £40 on last month and I've barely been home!
Running parallel Multis on a boat sounds like my static caravan setup but wetter and more expensive — went with twin 48/5000s myself and honestly the 10000s would've been overkill for what I...
@CotswoldNomad renting is the killer detail here — second-hand panels off eBay plus a Fogstar 12V LiFePO4 battery means you can literally chuck it in a van if the landlord changes their mind, ask...
EVE 280Ah are sitting around £0.07–0.08/Wh if you catch a Fogstar or CATL batch sale, though I swear the price changes every time I refresh AliExpress mid-coffee — grabbed a 16S pack last spring...
Been down this exact rabbit hole with my static caravan setup — bought all the "main" bits (Victron Multiplus-II 3kVA, Fogstar Drift 200Ah, 400W of panels off eBay) and then stood in the...
Right, been down this rabbit hole with my static caravan setup and it's properly mental trying to get everything chatting nicely.
The Ethernet breakout board approach is solid if you've got the...
Cheers for the detail @HalfAJob. The 5kW sweet spot is where things get properly serious — you're past the "nice to have" phase and into "actually powers the kettle without...
Right, so I've got a static caravan that's become a bit of a battery money pit and I need to work out if I'm being a complete muppet with my sizing.
Currently running a 10kWh lithium setup...
8kW sounds decent on paper but you'll find yourself charging the motor at 2am when the sun's having a laugh, mate.

Mate, "material change of use" is council-speak for "we haven't got a clue what you're doing but it sounds expensive." Had similar grief with my static caravan setup — they...
Mate, I've got a Fogstar 200Ah LiFePO4 in the static caravan and it genuinely plays dead below 5°C — cost me a fortune in heating tape before I stopped being a cheapskate about it.
The trick is a...
Mate, before you drop £2-3k on 200Ah, have you actually measured your winter consumption? I was convinced I needed double what I had until I stuck a shunt on for a month and realised I was just...
