1. 120 Volts AC500+B300S Backup System
AC500+B300S's Machine Type is set to "Single Phase" by default. DO NOT change
this setting if you are operating a single AC500+B300S set.
To build the backup system, you need the following:

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:
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.

Split Phase Backup System
Caution! The backup split phase system must be properly installed by a
licensed electrician.
How to configure the AC500+B300S sets:
Step 1: Turn off both AC500+B300S sets.
Step 2: Connect AC500+B300S sets to transfer switch via the AC500 split-phase
output cable. One NEMA 14-50 plug goes to a set.
Step 3: Connect two AC500 units via the communication cable.
Step 4: Turn on either AC500+B300Sset.

NOTE:
•Disconnect the AC charging cables from AC500+B300S sets before connecting to
the transfer switch.
•The split phase system can be controlled ONLY on the “Master” set.
•If one of the AC500+B300S sets is out of power, the split phase system
fails automatically.
NOTE:
•The backup system must be properly installed by a licensed electrician.
•Please check the voltage at outlets before plugging in your household appliances.
•It is a electrical schematic. For the actual wiring diagram, please refer to Reliance
PRO/TRAN2 installation instructions.
•In the main panel, two Neutral/Ground bus bars have been connected together
with copper strips.

Connect the AC500+B300S sets to the main panel
Charge the 240V split phase system with AC500 split phase AC charging cable. Plug
the cable to a NEMA 14-50 socket (240V )and the other two connectors into AC500s’
AC input ports.
The AC input ports should be connected to L1/N/PE and L2/N/PE, respectively. The
current capacity of AC input plug shall be ≥ 50A.
WRONG CONNECTION
Warning! DO NOT charge AC500+B300S with standard AC charging cable in the
split phase system, as this may cause damage to the batteries inside B300s and
invalidate your warranty.

3.8 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.
