6. Warning: Before proceeding, ensure that the battery powering the Any-Grid is sufficiently charged or,
if you are using an AC source, that it will not be interrupted for at least 20 minutes.
Click “Yes” when asked if you are sure, to proceed with flashing the upgrade of the firmware:
7. The Upgrader will now proceed to erase the flash memory of the Any-Grid and replace it with the updated
file. It is normal that the Upgrader software may appear not to respond for a few seconds. The progress is
shown, and the upgrade typically takes 10 ~ 15 minutes. Make sure not to interrupt the upgrade during
this time.
8. Once the progress reaches 100%, the Any-Grid unit will restart automatically. The Upgrader software will
show an “Upgrade success” message. This can now be dismissed, and you may exit the Upgrade software.
9. The Any-Grid may be disconnected from its power source 2 minutes after its automatic restart is complete.
Alternatively, you may now reconnect the battery or AC input, whichever was disconnected during the
procedure. Then continue to connect the PV array and loads as required.
10. The “Main Unit” upgrade procedure is complete. You can check the new version number as described in the
chapter “Introduction” of this document.
