120 Volts AC300+B300 Backup System

AC300+B300’s Machine Type is set to “Single Phase” by default. DO NOT change this setting if you are operating a single AC300+B300 set.
To build the backup system, you need the following:

Accessories	Qty.
Transfer switch: Reliance 370A Pro/Tran 2	1
NEMA TT30-P to Ll4-30R extension cord	1
30AAC charging cable	1

NOTE: Please read the Reliance 310A Pro/Tran2 manual before installation.

Refer to the diagram below for proper installation of AC300+B300 backup system.
NOTE:
1: TT-30 Socket
2: NEMA Ll4-30 Inlet on the transfer switch
3: 30A AC Charge cable
4: TT30-P to N EMA Ll4-30 extension cord

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.

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 370A Pro/Tran 2	1
AC300 split-phase output cable	1
NEMA Ll4-30R socket	1
AC300 30A split phase AC charging cable	1
Communication cable for split-phase function	1

Please read the Reliance 310A Pro/Tran 2 manual before installation.
http://www.reliancecontrols.com/Documents/PT2%20Loadside%20lnstallation%20and%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:

1: NEMA Ll4-30 Socket (Connect to AC300 Input)
2: NEMA Ll4-30 Inlet (Connect to AC300 Output)
3: 30A Split-phase AC Charging Cable
4: 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 Ll4-30 socket (240V )and the other two connectors into AC300s’ AC input ports.
The AC input ports should be connected to Ll/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)
