Transfer switch: Reliance 310A Pro/Tran 2	1
NEMA TT30-P to L14-30R extension cord	1
30A AC charging cable	1

240 Volts AC300+B300 Backup System

You can build the 240V Split Phase System by pairing two sets of AC300+B300 together. The system also has double the available output power and capacity. Besides TWO sets of AC300+B300, you also need the following:

Accessories	Qty
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%20Loadside%20Installation%20
and%20Operating%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.

NOTE:

NEMA L14-30 Socket (Connect to AC300 Input)
NEMA L14-30 Inlet (Connect to AC300 Output)
30A Split-phase AC Charging Cable
AC300 Split-phase Output Cable

Caution! The backup split phase system must be properly installed by a licensed electrician.

How to configure the AC300+B300 sets:

Step 1: Turn off both AC300+B300 sets.
Step 2: Connect AC300+B300 sets to transfer switch via the AC300 split- phase output cable. One TT-30 plug goes to a set.
Step 3: Connect two AC300 units via the communication cable.
Step 4: Turn on either AC300+B300 set.
Step 5: Go to “Settings” and tap “Next”.

Step 6: Tap “Single Phase”, the machine type option pops up and select “Split phase”.

Machine Type: Select Split Phase

Step 7: Select the “Master” in the Machine Address pop up.

Step 8: Turn on the other AC300+B300 set. Repeat step 5 and 6 to set its machine type to “Split phase”.
Step 9: Select the “Slave” in the Machine Address pop up.

If the connection fails, clear the alarm history and reconnect.

NOTE:

Disconnect the AC charging cables from AC300+B300 sets before connecting to the transfer switch.
The split phase system can be controlled ONLY on the “Master” set.
If one of the AC300+B300 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 AC300+B300 sets to the main panel
Charge the 240V split phase system with AC300 30A split phase AC charging cable.
Plug the cable to a NEMA L14-30 socket (240V )and the other two connectors into AC300s’ 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 ≥ 30A.

WRONG CONNECTION
Warning! DO NOT charge AC300+B300 with standard AC charging cable in the split phase system, as this may cause damage to the batteries inside B300s and invalidate your warranty.

L: Live wire N: Neutral wire

NOTE :
The split phase system supports charging via solar panels. You can charge it by PV and the AC300 30A split-phase AC charging cable simultaneously. (AC input only through the AC300 30A split-phase AC charging cable but not the standard AC charging cable)

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.
