Notes
Connect all batteries together with the provided RJ45 cables using the “RS485B/RS485C” ports. Either port can be used for each battery. Up to 15 batteries can be connected in parallel.
Binary Numbering
Set the DIP switches such that the battery communicating with the inverter is set as ID 1, and each unit behind it increases the follower ID by 1 from left to right.
Each DIP switch (1-4) represents a bit in the follower ID value. For example: 13 (decimal) =1101 binary = [1: ON, 2: OFF, 3: ON, 4: ON].
Decimal counting from 0 to 15 in binary format as a 4-bit nibble (half byte):
00 - 0000
01 - 0001
02 - 0010
03 - 0011
04 - 0100
05 - 0101
06 - 0110
07 - 0111
08 - 1000
09 - 1001
10 - 1010
11 - 1011
12 - 1100
13 - 1101
14 - 1110
15 1111
Communication Cable
Connect a standard CAT5/6 cable between the “CAN” port on the Master battery and the “Battery CAN Bus” port (or the “CAN” port for indoor-only units) on the Sol-Ark.
Turn on the breakers of the batteries and inverter.
Use a thin tool to press in the “RST” button in any of the batteries to turn all of them on. You can now turn on the inverter if it is not on already.
BMS 00
Program the inverter with this battery's appropriate charge/discharge settings.
Enable “BMS Lithium Batt” and set its value to “00.”
BMS Error Stop Option
If you wish for the system to fault on the loss of battery communications, turn on “BMS_Err_Stop”
