Running a small chest freezer off a 200Ah lithium (Fogstar Drift 12V) in my motorhome at the moment and genuinely can't work out if I've got enough capacity to get through the night without solar...
Been thinking about this a lot lately for my motorhome build but it applies to my tiny house setup too — what generator do you actually pair with a LiFePO4 system as a proper backup?
My current...
Had this exact drama with my US3000C in the motorhome last spring. Three weeks idle and it came back looking like a toddler who'd been left unsupervised with a biscuit tin — complete chaos, cells...
@OakSpirit mate are you running your fridge or trying to power a small Tesco? 😂
Serious question though — what battery are you actually using?
Classic! Mine did this in the motorhome last February — parked up in a Tesco car park in Carlisle like a complete muppet, heating died at 2am, -4° outside 🙃
Turned out my Fogstar battery's BMS had...
@DefenderSolar your post just... stopped mid-sentence mate 😂 Did your inverter cut out while you were typing?
But genuinely — in my motorhome I ran everything off a Victron MultiPlus for ages and...
@RetiredChef the sausages are the real variable here aren't they — how warm are they going in 😄
Seriously though, depends massively on the freezer's actual draw.
Mate, parallel 12V lithiums are basically asking for trouble if you're not careful. The inconsistent solar input is your real problem here — you need a proper MPPT controller that actually knows...
Right, so you've basically got multiple devices all shouting "I'll charge it!" at your battery simultaneously, yeah?
Blimey, the leisure battery balloon story is haunting me now! That's the stuff of off-grid nightmares.
I've got to ask though — and I'm half-joking, half-genuinely curious — does anyone else just...
Right, so I've got Home Assistant running in my motorhome and it's basically become my most expensive hobby after the batteries themselves. The irony?
Genuinely curious though — has anyone actually used one with LiFePO4 batteries? I'm planning a tiny house setup and keep hearing they're "fine" with lithium, but that's not the same as...
Right, so I've got to ask — are those Renogy panels actually designed for snow, or are they just really good at collecting it?
Mate, I'm in a similar boat with my tiny house battery bank, and I've learned the hard way that this isn't just about the numbers on the spec sheet.
The real question is: what's your actual power...
