4.Cable connection for Parallel connection

4.1 Ground installation

For parallel installation, please pay attention on Cable connection, and the DIP8 of SW2 no

need to be changed and stayed on Initial Factory state.

4.2 Wall mounting

For wall mounting, the battery Series connection number should be less than 4, if more

batteries installed, a cabinet was recommended.

Note:

Before two or more batteries installed in parallel, please check the voltage of

each battery and make sure the voltage different less than 2.0V.

5. Configuration

5.1Settings for CAN /485 bus pins

SW1,SW4 and SW5 should be set correctly for proper communication between inverter and

battery.

SW1: For CAN communication, please set pin1 and pin2 at on, pin3 and pin4 at off

For 485 communication, please set pin1 and pin2 at off, pin3 and pin4 at on

SW4,SW5: Please use them to set the port of RJ45

Low signal (CAN) / B (485)--SW4

High signal (CAN) /A (485)--SW5

Example (above picture )：CAN communication, port 5 of RJ45 is low signal, port 4 of RJ45 is

High signal.

Note:

The battery default protocol is CAN bus, if an inverter communication mode is

RS485 or other protocol, please contact AOBO before installation.

Grounding Cables

6.Commissioning

6.1Commissioning battery

If there is only one battery installed, use the following steps to put it in operation:

1.Press and hold the panel button on the left side of the unit for about 5s, after the indicator

lights on, release the panel button.

2.Make sure that the Run light is on. If it stays off, do not use the battery and contact AOBO

or your distributor.

3.Turn the inverter on, and wait for the start-up sequence to complete fully.

When there are two or more batteries connected with parallel mode, after the charging cable

and the data cable has been connected correctly, follow these steps to put them in operation:

1.Check battery voltage level is above 48V

a)If battery voltage is under 45V contact your distributor or AOBO after service hot line for

help.

2.Press and HOLD the panel button for about 5s, then the indicator lights will turn on.

3.Release the panel button.

a)For all batteries, make sure that the Run light is on.

b)Make sure the maximum voltage different between batteries less than 2.0V.

c)If not, the installer should balance the battery voltage and then parallel connect batteries

together.

d)Set the DIP switches like part 5-1 Setting for communication interface.

4.Turn the inverter on, and wait for the start-up sequence to complete fully.

6.2Shutting down battery

1.Press and hole the Panel Button about 5s, after a disconnect voice of relay come can release it.

2.Make sure that every light on the battery is off.
