Questions for those with battery storage on their setups - how are you finding winter charging rates from the grid overnight?
Octopus Go 0030-0430 window, but for the first time (kicking myself for not thinking about this earlier, but live and learn!) I'm thinking the dips to 8-12c overnight for the batteries outside are limiting charge rates (understandably takes a while to get up to 'normal' rate)
Typically during 'warmer' times weeks back, the two inverters and batteries would be at 10-12kwh peaks charging the banks, whereas now its 4-8kwh rates.
Have begun having the units 'start' at midnight to give them a 30minute warmup before the offpeak kicks in.
Setup: twin solax hybrid inverters (6k peak per) + 35kwh attached storage.
Day time solar is meh in winter, so batteries picking up the slack.
