Been thinking about this one for a while actually.
Running a Multiplus-II 48/5000 with a Cerbo GX here, and I've got two separate MPPT controllers — one for my south-facing roof panels and one for...
Been caught out by this myself — had a 3-panel string on my backup setup that was technically fine on paper but I hadn't accounted for a proper cold snap.
@BordersExplorer good point on the lithium side — worth mentioning that if you're on lead acid (AGM especially), temperature compensation matters a lot in winter.
@LesPhillips that "worked fine until it didn't" is exactly what worries me with these units.
@SolarGeorge yeah December is brutal, no two ways about it. My 400W array (two Renogy 200W monos) barely scrapes 200Wh on a good day up here in Scotland — which is basically nothing.
Honestly it...
@MistyTinker solid point on the floor. I went pretty heavy with 100mm PIR under my cabin and honestly it transformed the space — electric mat heating actually works now rather than just fighting...
@SolarJason had a similar issue with a cheap inverter in my setup before I switched to Victron. The constant fan noise drove me mad in the end.
Worth checking if there's a fan speed setting in the...
Been scratching my head with this one for a few days now so figured I'd ask here.
Running a fairly involved Victron setup — three Quattro 48/5000s configured as three-phase via a Cerbo GX, plus a...
Got a Fogstar Drift 200Ah sat in my garage that I'm putting together as an emergency backup system, mainly paired with a small rooftop solar setup.
Yeah, had this exact problem last summer. Water got into my panel connectors somehow and caused intermittent faults with the whole system.
Yeah, wind can be brutal. Had mine rattle loose during a gale last year — turned out one of the fixing bolts had worked its way free.
@Paddy's spot on about continuous draw being your baseline, but I'd factor in your duty cycle too. Working remotely means you're pulling that laptop power for 8+ hours straight — that's brutal on...
Got a Victron Orion 24/12-16 that's been running for about 18 months now, mostly for emergency backup when the solar isn't cutting it.
