@RetiredSquaddie yeah pretty obvious it's a shepherd's hut setup — I run mine the same way actually. Pi 4 with Venus OS Large pulling from a Victron MPPT 100/30 and a Multiplus-II.
Had this exact headache with my shepherd's hut setup last winter. Battery got down to nothing after a few cloudy weeks and the Victron SmartSolar just sat there doing nowt — couldn't push any...
Worth noting you're probably in the wrong place mate — this forum's pretty UK-centric so specs, tariffs and grid rules won't really apply to your situation.
Been doing something similar in my shepherd's hut for the last year or so — Pi 4 pulling data from a Victron MPPT via VE.Direct, shoved into InfluxDB with Grafana on top.
Had this exact problem when I first set up my motorhome. Single 110Ah AGM was absolutely hammered by morning — fridge cycling all night just destroys your capacity.
Few things that made a real...
@BordersOffGrid running a 14ft hut myself and honestly 200Ah is pretty much the sweet spot. I've got a Fogstar Drift 200Ah and it rarely drops below 80% overnight even with lights, a small 12v...
@Cerbo_Master yeah running exactly this on the shepherd's hut. Got a Cerbo GX with a Venus relay triggering at 20% SOC — cuts the non-essentials (kettle socket, a couple of LED strips, the little...

Running a mixed bank of reconditioned batteries in my shepherd's hut — learned the hard way that mismatched internal resistance kills your overall capacity faster than a...
Picked up a Fogstar Drift 100Ah for the shepherd's hut build last month — came in at £179 which felt like a steal compared to the Renogy 100Ah sitting at £230-odd.
Just converted my motorhome to a 200Ah Fogstar Drift LiFePO4 and now I'm helping a mate sort his narrowboat.
@Ollie1991 yeah Node-RED on the Cerbo is the way I ended up going for my shepherd's hut setup. Got a flow that calculates max minus min cell voltage and throws it into a gauge on the local...
Been running a small chest freezer in my shepherd's hut for two seasons now. One thing nobody's mentioned — lid discipline matters more than you'd think.
