[QUOTE="johnb2713, post: 553360, member: 35153"] Do you have a tariff that gives you off peak energy at a lower cost eg Octopus GO? If so I would adjust the charging schedule to charge your battery to 90% for the full duration of the off peak time (for GO that would be 00:30 to 04:30). The house loads would all be supplied at the off peak price and your storage battery would be charged to 90%. At 04:30 your storage battery would be supplying your house until such time solar takes over or the battery becomes discharged. [/QUOTE]
