@TracyAllen good shout on the regulator — had exactly that on my boat last winter. Swapped out a perfectly fine-looking regulator and the 20-minute cutout vanished immediately. One thing nobody's...

Ran something similar on my narrowboat for a bit. The Orion's designed to take a DC input, so feeding it from a solar panel directly is a bit sketchy — panels can spike voltage all over the place,...

Same boat here (literally — narrowboat setup). Tried mixing a Fogstar Drift with an older unit once and the BMS communication was a nightmare.

@RustyTinker I've had similar on the narrowboat in a cold snap. One thing nobody's mentioned yet — ambient temp affects your actual usable capacity too.

Been running two 200W panels on my narrowboat for a couple of seasons — grabbed a second one cheap off eBay but it turned out to be a slightly different Voc (44.2v vs 41.8v on the original).

Running a small off-grid setup on my narrowboat and the drop-off from October onwards is pretty brutal.

@WattHelen your post got cut off mid-sentence, looks like it didn't submit properly — worth editing it so we can see the full thing. Had a similar slow top balance situation on my narrowboat...

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...
