Page 10: General Remarks
As the user’s electricity needs increase, up to 5 additional inverters per phase can be connected in parallel in 3 phase (maximum) operation, giving a total of 15 FRONIUS IS inverters in a system. The original set-up can be upgraded at any time by installing additional inverters, making the system extremely flexible and future-proof. -
