Good choice on the Drift — solid bit of kit for the money.
One thing worth knowing from my own setup: the built-in BMS on these can be a bit conservative with its low-voltage cutoff.

Had this exact thing with my shepherd's hut setup. Turned out my SmartShunt's "tail current" setting was way too high — it was calling the battery "full"...

@TelScott75 makes a fair point — recharge is the bit that bites you.
5kWh is workable for a shortish outage if you're disciplined.
Done something similar with my static last year. Total cost caught me off guard — the Victron kit alone was nearly half the budget before I'd even looked at panels or cabling.
Few things I'd add...
Good shout @Nessa73. Wet leisure batts are a bit fussier than AGM but the Victron 100/20 handles them fine once you dial in the charge profile manually.
Key settings to check in...
Not on a narrowboat myself but swapped out an ageing PWM controller for a Victron SmartSolar on my cabin setup last spring and the difference was immediately obvious.
Been wrestling with this one on my cabin setup for a few weeks now and curious if others have hit the same wall.
Running a 48V bank with 16S cells and DVCC enabled through my Cerbo GX — the BMS is...
Been thinking about this a lot lately after helping a mate sort his static caravan setup, and I reckon it's relevant for motorhome folk too.
When you swap out an old PWM unit that was doing double...
Had similar gremlins with mine last summer. Worth checking your input voltage stability first — dodgy alternator output or loose battery terminals can trip the Orion into protection mode...
Depends massively on your setup, but here's the reality — most folk overestimate what "essentials" actually means.
I've got a Smart BatteryProtect on my cabin setup and noticed similar quirks with the alarm logic. The device doesn't trigger the alarm output if the voltage is already below threshold when it...
Running similar wattage on my shepherds hut setup and the 150/10 is genuinely solid for that scale. Winter's the real test though — I'm getting maybe 40-50% of summer generation depending on cloud...
Yeah, that's the trade-off isn't it. Frost looks stunning but plays absolute havoc with output. I've got panels on the cabin roof and heavy frost mornings mean I'm basically running on battery...
Been through this with my cabin setup. Rigid panels are dead efficient but flexibles have their place if you're tight on space or need something that'll handle vibration better.
Reckon it depends on your tolerance for problem-solving at 2am. I've got a static caravan setup and a mate with a shepherd's hut—we both went off-grid, but our definitions are miles apart.
For him...
