@EcoFlowMaster here's how I'd think about it properly:
A 200Ah at 12V gives you 2,400Wh total. With lithium you can realistically use 80–90% of that, so call it ~2,000Wh usable.
Assume a 10-hour...
@Cleggy exactly right — it tracks the charge curve precisely because what you're hearing is the switching frequency of the converter interacting with the magnetics inside.
Had a frustrating evening last week that I reckon some of you will recognise.
Been running a single Multiplus-II 48V/5000 here for a couple of years — originally on AGM, no dramas whatsoever.
Been through something similar fitting a Victron SmartShunt 500A into a Transit-based camper conversion a couple of years back, so this thread caught my eye.
The factory dual-battery setup on...
Absolutely worth checking — learned this the hard way about three years ago when I picked up a "bargain" 250W panel from a van conversion lad who'd clearly left it face-down on gravel...
Been watching this one with some curiosity since the V1 landed. The wall-mount form factor is genuinely clever for tight installs — I've got a Fogstar Drift wedged into an awkward corner in my...
@FormerMechanic74 not overkill at all — it's the only sensible approach once your system grows beyond a handful of components.
Ran a Pi 3B+ for two years before upgrading to a Pi 4.
The Fogstar 4G route is solid, but I'd flag a couple of things from my own setup out here. First, make sure your Cerbo's getting stable power — I had intermittent VRM drops that turned out to be...
Yeah, the 50% rule nearly scuppered my battery storage shed plans. Turned out my LA had a different interpretation than the planning portal suggested.
Spot on about the degradation — I learned that the hard way. Had a set of Renogy flexibles on my van back in 2019, and after about four years they'd dropped to maybe 85% output.
Right, thought I'd document this before I forget the details. Picked up a decommissioned ambulance last year—absolute unit, and the electrical skeleton was already there which saved me a...
Spot on about the proper crimper—I made the mistake of borrowing a mate's generic one and got inconsistent pressure. Invested in a dedicated MC4 tool and never looked back.
The circular saw thing's real. I learned that the hard way—nearly blew my Victron when I fired up the angle grinder without killing the workshop lights first.
Right, been down this road myself with my narrowboat setup, and the pub advice is probably why you're confused—most people just repeat what they half-remember.
The real issue nobody's mentioned...
The inrush current is the killer most people overlook. Your fridge compressor will pull 3-5x its running wattage on startup — that's the real story here.
I went down this road with a shepherd's...
