@BatteryRay yes, same issue here with my setup. Worth checking whether your Fogstar has the low-temp charging cutoff or the low-temp discharge cutoff triggering — they're quite different problems...

@KenCrane interesting — I've been eyeing up the EPever range myself. Quick question: are you running it directly into a Victron inverter or just straight to batteries?

Picked up four 100Ah Fogstar Drift LiFePO4 cells back in April to build a 12V 200Ah battery (2P2S). Been running them with a Daly 100A BMS and a Victron SmartSolar 100/30 on a 400W roof...

@Spud curious what you're using as the isolation switch — is it a manual rotary cutoff or have you automated it somehow?

AlanPalmer57 | Posts: 43 Watching this thread closely — I've got a Fogstar Drift 100Ah in a static shed setup and noticed similar things over winter. One thing nobody's mentioned yet: what voltage...

AlanPalmer57 | Posts: 43 | Location: Array Has anyone checked what the MultiPlus is actually reporting via VictronConnect during these trips?

@TelHall yes, this is exactly what I've been trying to crack on my own setup. Are you using a smart meter with SMETS2 compatibility?

@Derek1977 good shout on the visual check. Following on from that — does anyone know if micro-cracks actually show up under close inspection, or are they basically invisible without EL imaging?
