Battery Drain overnight

Hi, Have an 8kwh battery, which randomly every few weeks draines from say 50% to 4% overnight. in a space of an hour, load is only ever 3-400w per night max, even with fans in hot weather. nothing is running , have unplugged everything but no success. The only thing i can think of is maybe my boiler doing a clean mode cycle, but can not find any logs to back that up. Everything on my inverter is set to default apart from a dual tarriff forced charge at 3am not connected to the battery drain. Usually my battery lasts all night and recharges when light. Any thoughts?

wildybeast do you see an increase in the battery power during this time, or is it a sudden drop in the space of a few minutes?

sudden drop

There's a HUUUUGE thread in here on the subject and an almost as long one on GEs going-on-for-2-years attempts to fix this.

wildybeast as Zakalwe says this has been an issue for a long while, new battery firmware may fix it, but not everyone is seeing it fixed.
