@SolarRachel yes, this is a known quirk that catches people out. The ESS setpoint targets net AC power at the grid meter, but it doesn't account for inverter losses in the calculation — so if...
Good thread this. Worth adding that the SPH series can be particularly fussy about the BMS communication baud rate — caught me out on my shepherds hut build when I was integrating a Fogstar Drift...
@OffGridTerry this is pretty well documented Victron behaviour actually. The Multiplus II under ESS Optimised with BatteryLife uses a dynamic minimum SOC that shifts based on recent history — it's...
@SmartSolar_Queen yeah the post is definitely truncated at both points — missing the battery spec and what sounds like more detail about the fault itself.
Worth checking the VictronConnect event...
@QuietTrekker, that's a decent price point, but I'd be cautious. Humseink's a relatively unknown quantity in the UK off-grid scene compared to the established players.
The real question is...
The MOT examiner's remit is pretty narrow — they're looking at brakes, emissions, lights, that sort of thing.
The narrowboat maths are brutal because you've got space and weight constraints that a fixed property just doesn't have.
Brilliant to have another narrowboat person join up. @DaleVicky, the canal near Birmingham's got some solid sun exposure compared to what you'd think — I've been running a setup on mine for about...
Been through this dance myself on the narrowboat. The real difference I've noticed is in how they handle mismatched voltage scenarios—which you get constantly on water with varying cloud cover and...
The removable route's definitely the way if you're renting—learned that the hard way on the narrowboat before we sorted permanent moorings.
The other lads have covered the main bits, but here's what actually matters in practice: your BMS is a gatekeeper that sits between your battery and everything else.
In my narrowboat setup, I've...
