[QUOTE="Figrol, post: 543027, member: 36016"] I also wanted to charge my batteries from cheap overnight electricity and followed John's advice from many weeks ago on setting this up. It worked and I've selectively charged my batteries overnight to 90%, 70% and 50% depending on what I thought the weather the next day would be. So in my case, the overnight charge charges the batteries to 90%. They stay at 90% until 04.30, when my Octopus Go day rate kicks in. I can see that once the 6.6 kwh batteries reach the set SOC overnight at about 02.30, my overnight house load is fed by the grid until 04.30. At this point, the battery SOC starts to drop as they feed my house until the sun is up and then depending on the cloud cover, etc. the load is fed by a mixture of battery and grid power. My panels are west facing, so that on a sunny day by late morning/early afternoon there is enough PV power to feed the house and start to recharge the batteries, but now the batteries will go to 100% SOC. the only difference between my set up and John's is that my 'Power Harvester' is set to 'WiredCT' and John's was to 'Meter'. However, I can't see how this would affect the battery charging limit points. [/QUOTE]
