"Wi-Fi dongle is mounted on a Solar Inverter System, which converts DC power generated in Solar panel into AC power, to communicate between Solar Inverter System and the server in a wireless environment Because Solar Inverter System is installed in Boiler room, warehouse, garage in home, the distance from the end user is maintained at least 20 cm in the real circumstance. So, it meets mobile use conditions for RF exposure compliance. In addition, there is Driver S/W for operating the Wi-Fi dongle, which is provided only to the solar inverter system manufacturer. When the Solar Inverter System is manufactured, the driver S/W is installed in the factory. End user cant access this Driver S/W. For the reason above, Wi-Fi dongle cannot be used with a notebook or device for General Public. Sincerely Yours,
