Deka-Duration-DD5300
No additional hardware is needed to establish communications with Deka-DD5300 batteries.
• Please ensure that you are not wiring to the High Voltage connection terminals of
Deka-DD5300 battery.
• Please refer to the Installation & Operation (I&O) manual of the battery manufacturer
and verify the proper communications configuration of CAN bus connections and dip
switch settings:
• A custom cable is required to establish communications with Deka-DD5300 batteries.
Communications Installation and Setup Instructions
1. Create a custom cable that connects pins 1, 2, and 3 ONLY (white-orange, solid orange,
and white-green) on the battery.
2. Pin three (3) (white-green) should connect to pin six (6) on the inverter.
3. Pin one (1) (white-orange) should connect to pin four (4) on the inverter. Pin two (2)
(solid orange) should connect to pin five (5) on the inverter.
a. On indoor units, connect pin three (3) (white-green) to pin two (2) on the inverter
instead of pin six (6).
4. Connect the cable to the “CAN-A” port on the Deka-DD5300 and the “Battery CAN
Bus” port (or the “CAN” port for indoor-only units) on the Sol-Ark.
a. The cable is NOT reversible; therefore, keep track of which end of the custom
cable connects to the battery and the Sol-Ark.
5. Turn on the mechanical POWER SWITCH to enable the BMS on all battery modules.
6. Press and hold the RUN BUTTON for 2 seconds on the MASTER battery module only
and allow other modules to turn themselves on automatically. After a successful startup
of the battery modules the LED status indicator should turn solid green.
7. Program the inverter with the appropriate charge/discharge settings for this battery.
8. Enable “BMS Lithium Batt” and set its value to “00.”
9. (Optional) Turn on “BMS_Err_Stop” if you wish for the system to fault on loss of battery
communications.
