4Alarm state Center leaf; green light ashes (0.5 seconds on and 0.5
seconds off, 0.5 seconds on and 2 seconds off). Ring indicator-refer to Discharge state.
5Fault state Center leaf; red light ashes (1 second on and 1 second
off). Ring indicator-refer to Discharge state.
6Upgrade state Center leaf; yellow light ashes(1 second on and 1 second off) indicates the upgrade state. Ring
indicator-refer to number 1.
7Manual forced power
on
Center leaf; green light ashing (0.1 seconds on and 0.1
seconds off) . Ring indicator-refer to Discharge state.
8Manual forced
shutdown
Center leaf; red light ashing (0.1 seconds on and 0.1 seconds off). Ring indicator-refer to Discharge
state.
Note – All other components of the EI Battery Storage system, including the energy meter must be installed for the system to operate.
!CAUTION – For personal safety always wear appropriate PPE.
8. Forced start/shutdown
Check Item Acceptance Criteria

1. Turn ON the BAT-switch in the Inverter connections wirebox (8).
2. If multiple batteries installed, turn on the BAT-Expansion breaker in the Battery expansion wirebox (12). Otherwise, skip this step.
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. Conrm 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.

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.
Note – The opposite end of the battery conductors
are connected in the inverter wirebox as shown.
!CAUTION – Risk of electric shock! Ensure the inverter and battery cabinet are completely powered off when these
steps take place. Make sure to connect the battery inverter first and then connect the communications cable to the
inverter.

1. Loosen the two captive screws on the left side of the battery enclosure’s inverter connection wirebox (8).
2. Remove the two waterproof knockouts (5), (7) at the bottom of the left side of the enclosure. Connect two conduits from the battery
enclosure to the inverter. Use appropriate water-tight ttings.
3. Prepare two conductors, 10-8AWG with wire ferrules and route through the conduit.
4. Verify the BAT-switch is in the OFF position, and connect the conductors as follows:
1. Insert the battery conductors into the terminals of BAT+ and BAT- (EI Inverter Quick Start Guide 3.7).
2. Insert the RJ45-CAT5/6 communications cable into the INV terminal (EI Inverter Quick Start Guide 4.2).
5. Once complete, replace the wirebox covers and the enclosure cover by reversing the steps of section 2.4
