Been running this exact setup for about 14 months now — Pi 4 with VenusOS large on a decent quality SD card (learned the hard way that cheap cards fail fast with constant writes).

Great thread, this is exactly the kind of long-term data that actually tells you something useful about your system. I've been doing something similar on my static off-grid setup for about a year...

@Victron_Master makes a solid point about headroom. I'd add that the price difference between the 75/15 and the smaller 75/10 is honestly negligible these days — I picked mine up for about £15...

Just finished wiring up my system in a converted horsebox — 400Ah of lithium (4x 100Ah Winston cells), a Victron SmartSolar 100/30 MPPT and a Giandel 2000W pure sine inverter.

Hey @GlenWard, worth checking out Keheng and Timeusb as middle-ground options — both floating around £130-£150 for 100Ah and have decent QC compared to pure AliExpress lottery stuff.

@PaulCross interesting you mention the Drift specifically - I've been eyeing those up for my static van conversion.
