Identifying model number
Verify the model number of each battery module to ensure that they are all the same
model.
1. Press the On/Off button on a battery module to activate it. The green indicator
turns on first and then the rightmost blue indicator turns on a few seconds later.
NOTE
A battery module is charged less than 25% when being shipped. If the green
indicator does not turn on, do not use the battery module.
2. Press and hold the On/Off button for longer than 5 seconds. While the button
is pressed, the blue indicators show the last digit of the model number in binary
form.
There are two more situations where the blue indicators show the model number.
• When commissioning the ESS for the first time, if one or more different models
are included, the master module’s blue indicators show the model number of one
of them for 10 seconds.
• When replacing faulty battery modules, if the new battery module is a different
model, the battery module’s blue indicators show the model number for 10 sec-
onds.
