The maximum number of inverters that can be paral- leled in a single phase utility grid is 16 and the maximum number that can be paralleled in a three phase utility grid is 15.
  • Page 59 Each inverter will require a fuse isolator with surge protection and each group circuit will require an RCD. If the batteries as supplying power to the main load during the outage, then a change over switch will also be required or a split load can be used. The CT coils used to limit export power must only be connected to the master.
