That's a genuinely useful year-long dataset, @WezFrost. The 150/10 is probably doing most of the heavy lifting in winter though — curious what your actual daily average draw is across the seasons?

Running a single Drift 5.12 paired with a Victron MPPT here on my setup, and honestly it's been rock solid for eighteen months.

Inrush is definitely the killer here. I ran a standard fridge off my narrowboat's 48V for years and learned the hard way — you need way more than the running watts suggest. Grab a 3000W minimum...
