The SmartShunt's voltage monitoring is decent but honestly the shunt resistance can be a faff to dial in properly.
Right, so the battery's your bottleneck here. I've got 8kW solar feeding a 10kWh LiFePO₄ and even that struggles in winter—charge controller maxes out before battery's full. Summer?

Not dreaming, but the maths gets uncomfortable fast once you really dig into it. I've got a 5kW array feeding my shepherd's hut setup, and I'll be honest—it powers the essentials brilliantly...

State of Charge — your battery's fuel gauge basically. @ZFS_OffGrid and the others have nailed the lithium bit. What I'd add from my motorhome setup: it's not just about longevity, it's about...

Been watching your progress with interest. Before you commit to the battery spec, have you calculated your actual daily consumption?

Absolutely mate, it's been a nightmare this year. My array's taken a proper battering from the local seagulls—they've practically claimed it as a communal toilet.

Been wrestling with external control settings on MPPT chargers myself, particularly when integrating with monitoring systems via VE.Direct.
I've been wrestling with this exact problem for the past couple of years. During summer when I'm away from the shepherd's hut for weeks on end, the battery bank just sits there fully charged with...

Mate, just stick a Kill-a-Watt meter on your shed setup for a week and see what you're actually burning through — beats guessing.
Been following this thread with interest, and I've got to say the EG4 combo is starting to look more viable than I thought six months back.

Ground-mounted's sensible, but don't overlook a portable setup initially. I started with a 400W Renogy panel and 200Ah LiFePO4 in my shepherds hut — cost me under £2k complete.

Right, curious about something here. I'm running a similar setup on my narrowboat – pair of Quatros with DVCC locked in tight to the BMS – and I've been wondering about bolting on extra charging...
Had this exact problem with my shepherd's hut setup last winter. Took me weeks to track down the culprit, so worth sharing what I learned. First things first—measure your actual drain.
Right, so I've been seeing something proper odd with my setup since pushing the v3.70 update through to my Cerbo GX last week.

Not entirely sure what happened with the OP there, but I'll chip in anyway. Wiring diagrams are absolutely critical—get it wrong and you've got fire risk or dead batteries.
That's a seriously capable setup, @MarineGaz. I've got a similar Multiplus on my boat and it's bulletproof for load switching. Real question though — how are you managing the winter charge cycles?
Been there with my narrowboat setup — 200W is tight for overnight draw. What's your battery capacity and what's actually consuming power after dark?

Been running through my system logs after swapping out a failed MPPT controller last week, and I've noticed my CCGX is sat on v3.60.

Been through two Fogstar units across different setups — van and tiny house. The 5.12's decent but watch the BMS firmware updates; mine needed a reflash at month 8.
Just got mine working properly after a fair bit of troubleshooting, and I have to say it's a solid pairing once you get the comms sorted.
