If installing only one enclosure, skip this step.
1. Using a Philips screwdriver, loosen 2 captive screws on the expansion wirebox (12) on the right side of each enclosure.
2. Install 2 conduits from the right side of enclosure 1 to the right side of enclosure 2 for the DC conductors and communication cable. Use appropriate
conduit ttings to provide a water-tight seal.
3. Prepare 2 DC conductors 6AWG and route through the conduit and one CAT5/6 with RJ45 connectors on each end.
4. Connect BAT-Expansion + from enclosure 1 to BAT-Expansion + of enclosure 2.
5. Connection BAT-Expansion - from enclosure 1 to BAT-Expansion - of enclosure 2.
6. Connect a communication cable from the Link Out port of Battery 3 (enclosure 1) to the Link In port of Battery 4 (enclosure 2).

3. Turn on the inverter, while waiting 10 seconds for the inverter to send the wake-up signal observe the LED indicator of the battery enclosure. Conrm the
battery system enters the discharge state (center leaf is lit).
4. The battery storage system has been successfully started.
To force start or shutdown the EI Battery:
1. Using a Philips screwdriver, remove the screws from the cover of
the forced start power button (6).
2. Press and hold the button for 10 seconds until:
1. OFF: The center leaf changes from green to red and begins
ashing quickly (0.1s on/off)
2. ON: The center leaf begins ashing green (0.1s on/off).
3. After the forced start/shutdown is successful, reinstall the cover.
8. Forced start/shutdown
4. Connecting the inverter
Note – This section corresponds to section 3.7 and 4.2 in the EI Inverter Quick Start Guide.
Reference that document by scanning the QR code.
