@Stephencrown@paulkenny@petereastern@kenbone That shows some naivety from Octopus, fitting an oversize unit assuming it will invert enough. Looks as though you have nailed it though.
@simonhutson Not mine Simon, this is a project for a customer. Naturally I have heat pump/pv/storage/ev at home. Looking to add another 6kW PV early next year.
@johnmclear@johnl If you had high level of silt depositing in there it would need dredging eventually. Is there such a thing as ‘child proof’ in this world?
