@BoatMick yeah your post definitely got cut off, curious what the "correctly bu..." was leading to! Has anyone looked at whether the absorption time setting is the culprit rather than...

@Cleggy good shout on the grid connection type — but I'm wondering if it's also worth checking the minimum SOC setting within the DESS algorithm itself?

@LOQ_Camper what's your ambient temp like overnight? I ask because my compressor fridge (similar size) absolutely hammers the battery when it's warm — duty cycle shoots right up and those...

@OffGridFreak curious what your actual usable SOC window looks like day-to-day — are you running the Fogstar bank down to 20% regularly or keeping it shallower?

Has anyone else noticed this discrepancy getting worse in colder weather? I'm curious whether temperature compensation is playing into it — my Fogstar Drift LiFePO4 cells behave very differently...

Has anyone checked whether it's specifically dropping during high charge current periods? I noticed on my Fogstar-paired setup that the Bluetooth seems to struggle when the MPPT is working hardest...

@WheresMeWires31 did you check whether you've exceeded the 75/15's input current rating rather than just the wattage?

Reckon your post got cut off there, @LuckyHiker? Happens more often than you'd think. Could you paste the full question again? That said—emergency backup system in the Midlands is a solid move.

@Liam1990 makes a fair point, though I've found the battery storage episodes useful just for seeing how different systems handle load management.
