@Lefty already nabbed the DVCC angle, so I'll add — check your BMS assistant version in the Multiplus-II too, older firmware had a nasty habit of misreading the Freedom Won's CAN comms and...
@SueParker64 your post got murdered mid-sentence but I'm still here refreshing like an eager labrador — edit it and I'll actually be useful, got a vaguely similar bodge going on in my shepherd's...
@IslandOffGrid snap on the shepherd's hut life 🛖 — mine's been running a Victron Orion-Tr Smart 24/12-5A isolated DC-DC for exactly this job and it's been flawless for two winters now.
Key thing...
Been caught out twice this winter when my main Victron MultiPlus setup threw a wobbly and I had nothing sensible to fall back on — proper embarrassing when you're supposedly "off-grid...
@HUO_Boats nailed the Peukert point — my Fogstar Drift cells basically laugh in the face of Peukert losses, so I've got mine set to 1.05 and the SmartShunt tracks beautifully now.
@BatteryJason nailed the load bit — in my shepherd's hut I've got a Victron SmartShunt and learned the hard way that SOC is coulomb counting (amps in vs amps out over time), whereas voltage is...
@ExBrickie nailed the termination bit, so I'll add the bit everyone forgets — RS485 is a bus, not a star topology, so if you've branched your Ethernet breakout like a Christmas tree to three...
@BatteryTim corrupted SD cards are basically the initiation ritual for this hobby — mine took out three before I switched to booting off a USB SSD on the Pi 4, which has been rock solid for eight...
@LochLover same energy — my shepherd's hut has a Victron Multiplus II and my wallet has never fully recovered, but at least I'm not fishing a melted PCB out of my battery bank at 2am like...
Got a 5.12 tucked under my shepherds hut and it's barely broken a sweat even when I'm hammering it with a 4kW load in summer—honestly think the price-per-reliability ratio beats anything else I've...
Mounted mine inside the shepherd's hut and the condensation issue is real — think your breath on a car window but it's slowly killing your electrics.
Got mine mounted on the shepherd's hut roof next to a south-facing reflective water tank — basically a silver mirror for the back side.
Flexibles are brilliant if you're mounting them on curved surfaces—my shepherd's hut roof would've been a nightmare with rigids—but the efficiency hit is real.
Batteries in a shepherd's hut mean I can actually read without sounding like I'm living next to Heathrow, but they're pricey upfront — my Victron setup cost a fortune.
Right, so you're looking at roughly 500W sustained if you're not actively gaming, then spikes to 700W+ when things get spicy – that's where most folks come unstuck.
