The first 2 unites DO NOT have AC in going to them, and are set to charge OSO ( Solar only). the third unit will have AC input and will be used for charging at night. My question is if they are all parallelled, can I set #3 to SBU while the other 2 are set to OSO, or do they all have to be the same?
