Fortress eFlex 5.4
No additional hardware is required to establish communication with the eFlex 5.4.
•You will need to make a custom cable for this setup.
Communications Installation and Setup Instructions
1. Connect all batteries using the included RJ45 cables.
2. Use the included 120 Ohm termination resistor on either end of the resulting chain.
3. Create a custom RJ45 cable where only pins six (6) (solid green), seven (7) (white-brown), and eight (8)
(solid brown) remain connected in their original positions, as shown in the picture below.
a. Using an ethernet cable that is known to work is more accessible and less prone to error.
Cut open the cable, and cut the unnecessary wires.
b. NOTE: If you are crimping new connectors to create a custom cable, be careful not to over-
tighten the crimping tool, as this can recess the connectors and lead to poor or intermittent
connection.
4. Plug one end of the cable into the CAN/RS485 port on the battery and the other into either the “RS-485”
(indoor models) or “Battery CAN Bus” (outdoor models) port on the inverter.

Fortress eVault & eVault MAX 18.5
No additional hardware is required to establish communication with the Fortress eVault 18.5 battery.
•You will need to make a custom cable for this setup.
NOTE: The original Fortress eVault can only communicate with the Sol-Ark AFTER a firmware
update to the eVault. New eVault units (including the eVault MAX) ship with this update;
however, older units may need the latest firmware update. To find out if your eVault needs the
update and how to perform this update, please get in touch with Fortress Power for details.
Communications Installation and Setup Instructions
1. If using multiple batteries, designate one as master and the others as slaves per Fortress’ setup
instructions. If using a single battery, skip to Step 3.
2. Connect the multiple batteries using an ethernet cable (RJ45 cable) as directed in Fortress’ setup
instructions.
3. Create a custom cable connecting pins three (3) and five (5) ONLY (white-green and white-blue) to the
battery.
4. Pin 3 (white-green) can be connected either to pin two (2) or pin (7) on the inverter.
5. Pin 5 (white-blue) can be connected to either pin one (1) or pin eight (8) on the inverter.
a. Since the eVault has no ground pin for communications, we recommend unchecking the
“BMS_err_stop” (under battery setup > discharge tab) so that noise on the communications cable
does not cause the inverter to throw a fault. This step is not necessary for the eVault MAX as it
has a ground connection.
6. Connect this cable between the Fortress eVault’s RS485 port and the “Battery CANBus” port (Outdoor
units) or the “RS-485” port (Indoor units).
7. Program the inverter with the appropriate charge/discharge settings for this battery.
8. Enable “BMS Lithium Batt” and set its value to “04.”
9. (Optional) Turn on “BMS_Err_Stop” if you wish for the system to fault on the loss of battery
communications
