2. 240 Volts AC500+B300S Backup System
You can build the 240V Split Phase System by pairing two sets of AC500+B300S together. The system also has double the available output power and capacity. Besides TWO sets of AC500+B300S, you also need the following:

Accessories Transfer switch: Reliance TRK0505BR
AC500 split-phase output cable NEMA 14-50 socket
AC500 split phase AC charging cable

Qty. 1 1 1 1

Before installing the Reliance Controls transfer switch system, please make a emergency energy plan that includes which appliances you need during a power outage. It is highly recommended to "balance the load" between the two phases of transfer switch, that's to say, do not connect high-wattage appliances centrally to a single AC500+B300S set.
