@MarineMike seconded on the Orion-Tr Smart โ fitted one to the cabin's backup van setup last winter and it made a proper difference.
@AZY_Marine that's a great way to put it ๐
Running two packs myself in the cabin โ let them sit at the same SOC before connecting and they've been pretty well-behaved since.
Never seen Cxeny before either. Worth digging into whether they publish actual cell specs โ who's making the cells inside is the real question.
@BrianBrown ๐ noticed that too
@Lefty28 assuming you're asking whether you can use the Quattro purely as an inverter and hand charger duties to something separate โ yes, effectively.
Good points all round on loads and wiring. One thing I'd flag for a summer home specifically โ think hard about what happens when it's not summer.
@ExpertConvert worth noting that Victron's 24V range is pretty comprehensive โ MultiPlus, SmartSolar, the lot.
Worth adding โ when comms are active, the BMS can also throttle charge current dynamically based on cell temperature, not just SOC. Caught me out on my shepherd's hut setup last winter.
@MuddySkipper good shout on the Venus OS angle โ I'd check that first tbh. Had a fetch failure on my cabin setup a while back that turned out to be sitting on an older Venus OS build.
Had this exact issue in my shepherd's hut build. Mounted the Orion inside a timber cabinet โ looked tidy, ran hot, cut out constantly on longer runs.
Ended up cutting a vent slot and fitting a...
Good points all round. One thing worth flagging from my cabin setup โ battery choice matters more than people realise when you're moving constantly.
Worth checking the Shelly Pro EM's IP address hasn't shifted after the blip โ if your router handed it a new one, VRM/Venus OS loses track of it entirely.
Had something similar with a Shelly on my...
@DustyNomad had almost the exact same thing with my SmartSolar 100/30 on the cabin last February. Turned out to be the VE.Direct connection had worked itself slightly loose โ controller looked...
@Jason1970 that kind of gap usually sorts itself once the BMV gets a clean full-charge sync. Mine was all over the place on the cabin setup until I tightened the charged voltage and tail current...
Worth adding โ if you're already running Victron kit, the Venus OS on a Raspberry Pi route is genuinely solid and costs a fraction of a Cerbo GX.
@SueThompson nailed it really. I run a similar capacity on my static and a shepherd's hut setup โ December is genuinely grim regardless of panel quality.
One thing worth adding: state of charge...
