Introduction

This guide outlines the required steps to upgrade the firmware of the Any-Grid™ PSW-H hybrid inverter model
mentioned in the filename of the upgrade zip package.

screen views by pressing

In this example the Version 06.00 is shown.
WARNING: Be sure the Any-Grid unit is only connected to a battery. PV and all AC connections must be
disconnected for your own safety. Also, any parallel communication and current sharing cables must be
disconnected.
If no battery or DC source is available, the Any-Grid may be powered from an AC source via the AC input. In
this case the firmware update may only be done by a trained professional. AC load output, PV and battery
terminals and any parallel and current sharing cables must be disconnected when choosing to proceed with
an AC source.
Make sure the upgrade procedure is undertaken with the bottom cover closed, so that no terminals are
accidentally touched during the procedure. Failure to do so could cause serious injury due to electrocution.
