I'm wondering if the possible setup/config is possible, I'm doubtful and someone has asked me and I'm curious of the answer.
Say you have a solar array and battery. I want the battery to charge overnight on the cheap rate (7.5p/kWh) and power the house loads all the time. I want solar to export all generation as I get paid 15p/kWh for export. So regardless of the house load, I want solar to export, not satisfy house load or charge the battery. I want battery to match the house load and discharge during the day, even when there is solar.
I appreciate this is an odd setup but I have a tariff where import is 7.5p/kWh and export 15p/kWh.
I'm thinking most setups could not achieve this but MPII and cerbo, with the right monitoring could see the house load and add that to the solar output as 'export' which the house will take part of and the rest will go to the grid. I appreciate you're limited to the AC output of the MPII (say its a 5kVA and you have more solar than that, it will still send some DC to the batteries to charge which makes sense)
Can it be made to work?!
