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.
