Sol-Ark Integration Guide

To create your own modified cable, you can use a variety of strategies:
1) A limited number of our vendors distribute a pre-made cable such as can be found here.
2) Crimp a custom RJ45 connector or use an RJ45 Ethernet keystone or cut and strip an Ethernet cable, twisting the
appropriate communication wires together with small wire nuts or electrical tape if necessary.
3) Most Ethernet cabling is Type B-format cable, but it is also common to find Type A-format cable. Tape the Ethernet
jacket back up when finished. You may use any Ethernet cable for this task.
4) Plug in the Battery end of the communication cable into the RS485 port of the master eVault MAX. This port will plug
into the Sol-Ark Battery CANBUS port as detailed in following steps, despite the name this port is also capable
of RS485/MODBus communication.
Additional notes:
1) It matters which side of the cable is plugged into the battery and inverter respectively (follow the labels on the cable
itself if using the included factory cable).
2) eVault MAX as of March 2022 are now shipping with a pre-made Sol-Ark inverter communication cable.
3) The yellow cable included with the Sol-Ark is fine stranded and difficult to crimp. If crimping a custom RJ45
connector, you may want to find an alternate cable to modify.
4) If providing your own RJ45 cable and routing alongside the battery power conductors, it is best (but not required by
Fortress) to use a shielded cable.
Program the Inverter
1. Start by pressing the gear icon on the top right of the inverter screen and then pressing the
battery setup menu (or use the online interface).
