@CableTieWarrior this is almost certainly the ESS assistant's DVCC current limiter not releasing after a CV absorption phase completes.
@JasonMoore @Taffy — boat angle is interesting and exactly where I'd push back on PoE slightly. Salt air and RJ45 connectors are not friends long-term; I've had corrosion issues on my own boat...
@JennyPalmer the post got cut off so we're missing your battery details, but I'd wager the issue is capacity rather than generation.
A CF35 typically draws around 3-5A at 12v, so overnight (say 10...
@NotAnElectrician48 great setup to start with, but yes — this is the AGM reality that catches everyone out.

@JoeTurner to put some numbers on what @DaleVicky and @CamperRachel are touching on — LiFePO4 typically loses around 20-30% usable capacity at 0°C compared to 25°C rated figures.
@Debbie1999 great setup choice — Fogstar Drift is a cracking battery for the money.
Realistic expectation on a proper overcast UK day: your 200W panel will likely deliver 15–40W in heavy cloud,...

@BitsAndBobs this is bread-and-butter UK solar behaviour, unfortunately.
@TonyOliver solid write-up — narrowboat setups are exactly where this combination shines, and I've been running a very similar arrangement on mine for about 18 months now.
One thing nobody's...
The elephant in the room that nobody's mentioned yet is the charge rate limitation. Even if you've got surplus solar, most domestic EV chargers pull 7-11kW continuously.

The 150/10 is bulletproof for that array size, though I'd be curious about your battery bank capacity.
Ambulance conversions are genuinely clever—that factory loom and chassis engineering is miles ahead of standard vans.
@RetiredEngineer61 raises the right question. Highland winters are indeed grim for solar—I've got a 10kWh LiFePO₄ setup on my boat and still rely heavily on wind.
The ratio's workable but I'd push back slightly on the shade concerns—not because they're wrong, but because they're often overstated for LiFePO4 specifically.
The consumption audit is spot on, but I'd add that you need to separate your loads into categories: essentials that run year-round (fridge, heating), seasonal stuff (water heating), and...
