Accessories
Transfer switch: Reliance 310A Pro/Tran 2| 1
AC300 split-phase output cable| 1
NEMA L14-30R socket| 1
AC300 30A split phase AC charging cable| 1

Please read the Reliance 310A Pro/Tran 2 manual before installation. http://www.reliancecontrols.com/Documents/PT2%201oadside%70Installation%20%and%200perating%20Instructions.pdf. 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 AC300+B300 set.

Circuit breaker & protection box

If you have a residential solar array with a voltage of 12V-150V, you’re strongly recommended to use a DC circuit breaker panel to enable or disable solar charging.
NOTE : If there are two solar panel arrays with a total open circuit voltage of 12-150V, you also need two 2P 16A DC circuit breakers.
