Worth noting that the RS 450/100 runs on a completely different architecture to the standard SmartSolar range — it's a synchronous buck converter rather than the usual topology, which is why the...
@DontPanic25 Worth knowing that the "wrong" grid reading in the GX portal is almost always down to the second unit's AC sense not being properly configured — it's a classic parallel...
Ran this same thing in my shepherd's hut for about two years. Pi 4 (4GB) with Venus OS Large, pulling from a Multiplus-II and a SmartSolar 100/30.
One thing nobody's mentioned — SD card failure is...
Had this exact problem with mine two years back. Before you start swapping components, check if the unit's in standby mode — there's a buried setting that kills the LED display if the remote...
Running 200Ah myself in the shepherds hut and it's been solid through winter. Worth checking if your actual draw justifies it though — I sized mine on worst-case December usage.
Spot on about logging, @PaulCross. I'd add—don't overthink the initial spec. Start undersized if anything.
The real question is what you're running through those winter months. 500W on a boat in December is actually not terrible if you're managing loads properly — I've seen folk with twice your panel...
Sticking with your Fogstars is definitely the right call here. The real issue isn't just the BMS disagreeing — it's that you lose any warranty support the moment you mix brands.

Real world - that 200Ah won't get you as far as the specs suggest. Friidge draw varies wildly depending on ambient temp, insulation, and how often the compressor cycles.
I've got a similar Fogstar...

The reality is it works brilliantly for some families and absolutely doesn't for others — there's no middle ground, really.
What I've found with my shepherds hut setup is that it's sustainable if...
Voltage drop's the real culprit nobody talks about until it's too late. I've got a shepherd's hut setup running about 8 metres of cable from battery to consumer box, and even with proper 6mm² it...
