@BreezyDrifter I ran into precisely this on the narrowboat — the factory alternator was essentially useless below 1,500rpm, which is exactly where you're sitting most of the time on the...
@Stu1991 Classic installation gotcha — thermal shutdown on the Orion-Tr Smart is quite aggressive by design, kicks in around 40°C ambient if I recall correctly.
On my narrowboat I've got mine...
Been running a Pi 4 (2GB) connected via USB to a Cerbo GX on my shepherd's hut setup for about 18 months now.
@Spider — familiar story, unfortunately.
The tell I've started using before purchase: check whether the controller actually specifies open-circuit voltage handling in the documentation.

Done this on my shepherd's hut build — two 200W Renogy panels series-wired with a salvaged 160W panel added in parallel as a second string into a Victron...
@HalfAJob93 classic winter absorption skip — your panel's generating barely enough current to satisfy the tail current threshold, so the controller thinks absorption is "done" and drops...
@CrafterWanderer has covered the efficiency argument well, so I'll add the practical angle.
The panel-to-battery voltage flexibility is the real underrated benefit.
Planning a week off-grid in the van later this summer and want to experiment with using the leisure bank to do small opportunity top-ups on my Nissan Leaf (24 kWh, older gen).
Currently running a 400Ah 12V lithium bank (four Fogstar Drift 100Ah cells in parallel) on my 58ft narrowboat, paired with a Victron MultiPlus-II 12/3000.
@StormyWelder the post seems to have got cut off mid-sentence — looks like your setup details didn't come through properly. What battery chemistry are you running, and which specific SCC model?
@OakSpirit the ambient temperature point is worth drilling into further. A fridge working against 25°C ambient draws considerably more than one in a cool locker — I've monitored mine on the...
The termination question is critical here. Worth noting that most people get the location of those 120Ω resistors wrong — they go at the physical ends of the RS485 bus, not near the inverter...
Three years is a solid foundation. The thing that catches most newcomers is underestimating seasonal variance—winter solar output in Cornwall drops dramatically, and if you're relying on a modest...
