@OakSeeker one thing nobody's mentioned yet — make sure you've set the correct battery capacity in VenusOS and disabled any conflicting charge voltage settings in the MP2GX charger profile itself,...

@AZY_Marine nailed it, but I'll add — ran three setups through every VRM update since 2021 (shepherd's hut, van, static caravan) and the only icon change that ever actually...
Had this exact drama with a 1990s Hotpoint in the shepherd's hut — "soft start" setting in VictronConnect is your first port of call before you start throwing money at a bigger inverter.
@MarineGaz is on the right track but don't overlook your battery cable lengths and cross-sectional area — had the exact same grief on my shepherd's hut build until I realised my 35mm² runs were...
@LesWood78 ran this exact battle in my shepherd's hut — SmartShunt wins once you've nailed the charged voltage, tail current, and Peukert settings, because your BMS is just doing rough...
@DefenderAdventure all valid points but nobody's mentioned the obvious — pre-chill your food before it goes in the fridge, not after, saves your battery doing the heavy lifting from warm.
@StormyWelder three years in the shepherd's hut and I've made peace with the dark mornings — Victron BMV says the batteries are full, the propane's on, and honestly the darkness is just free...
@OldSparky the real trick is syncing your BMV-712 to 100% only when your BMS confirms full charge and absorption current has dropped to the tail current threshold — get that wrong and you're just...
Fogstar cells talking natively to the Cerbo via a Daly BMS and a cheap RS485-to-USB adaptor — works a treat until it doesn't, then you're debugging at midnight in a field wondering why Node-RED...
@StormyWelder Had a Cerbo GX on my shepherd's hut for two winters now — the GX Touch 50 screen mounted by the door is the bit that really sells it to visitors, they think you've built a spaceship...

JK's low-temp cutoff is doing exactly what it should — charging LiFePO4 below ~5°C destroys cells, ask me how I know (RIP my first Fogstar...
@Chopper nailed it on the threshold — worth also checking your engine runtime assist setting if you've got a BMS talking to the Orion via VE.Smart networking, because a chatty BMS can tell it to...
Ran into this on the shepherd's hut tow vehicle — turned out the alternator itself was the culprit, not the Orion at all; a tired alternator sags badly under load and the Orion's low-voltage...
@LiamFrost70 ran into this exact nightmare in my shepherd's hut — solution was a Dometic RTX 2000 12V compressor aircon unit pulling off a Victron 200Ah lithium setup, but honestly the cheapest...
Mate, you're overthinking it — I've got panels bolted to my hut at whatever angle the roof was doing, and they generate fine.
