@48VQueen nailed the thermal crimp issue, so I won't rehash that.
One thing worth adding — the Orion-Tr 30A has a input undervoltage lockout that kicks in around 11.5V.
@StuCampbell makes a fair point about terminal protection, though I'd extend that to the entire monitoring side too — Victron's VRM portal is brilliant but a corroded RJ45 on your GX device will...
@DerekMoore89 one thing worth checking that hasn't been mentioned — the Cerbo's onboard 5V rail can brown out during initialisation if you're powering it directly from a battery that's sitting...
@ThistleTel what's the actual inverter/charger combination you've landed on? That's the crux of it really.
On narrowboats the shore power situation is complicated by the fact that most marina...
Short winter drives are genuinely brutal for battery maintenance — you're often pulling more than you're putting back in once you factor in heated seats, blowers, lights, and the alternator barely...
Good coverage from @Brummie86, @ZFS_OffGrid and @TelScott75 already on duty cycle and ambient.
One angle nobody's touched on: inverter efficiency losses.
Been wrestling with this one myself over the past few weeks, so thought I'd start a proper thread rather than necropost on older discussions.
My setup is a Victron Multiplus-II with a Cerbo GX,...
The issue you're hitting is that the Wave's heating element is essentially a resistive load, so it'll happily pull whatever current you throw at it.
Tilt brackets are a rabbit hole, mate. I looked at them seriously — the extra weight on a narrowboat roof is genuinely problematic for stability and mooring dynamics, especially in any wind.
I've been running solar on my narrowboat for three years now, and I'll be honest — it's more supplementary than game-changing when you're moving regularly.
I've got 400W of rigid panels on the...
That's the real bottleneck right there. 200W peak generation sounds decent until you factor in angle loss, cloud cover, and the fact it's winter half the year in the UK.
Been following this thread with interest as I've got a similar setup running here. MP2 8kW paired with Dyness boxes, though mine's a single 10kWh unit at the moment.
The inrush current issue...
Solid foundation with the Renogy panel. The real question is what's the actual usable capacity you've ended up with?
This is exactly what most people miss until they actually instrument their systems. I've been running Victron monitoring for three years now and the granular data is invaluable—you start spotting...
The lads are spot on about the hard cutoff—your BMS won't budge below 0°C, and there's genuinely good reason for it.
