13.1 How Do I Upgrade the Device Software Version?
NO TICE
● Before upgrading the ESS, check load cable connections to ensure that there is
no short circuit. Load short circuits may damage the system.
● Before the upgrade in a parallel system, check whether an iSitePower-M
communication failure or lithium battery communication failure alarm is
generated. If yes, clear the alarm according to the alarm handling suggestions
and then perform the upgrade.
● If the app is closed during the upgrade, the upgrade task will be interrupted.
● After the upgrade is complete, the device automatically restarts, which may
cause a power failure to loads.
● In the scenario with one power module and one battery module, connect the
iSitePower-M to the grid before upgrade. Otherwise, the upgrade will fail. If the
upgrade fails, connect to the grid and perform the upgrade again.
Scenario 1: Automatic Upgrade

After a user opens the app, if the system detects that a new software version
is available, a dialog box is displayed, prompting the user to download the
