   Get Enphase Solar Production, Consumption, and Net Use
.DESCRIPTION
   If you have not changed the password to your controller use the -SerialNumber, otherwise use -Credentials or -CustomPassword
.EXAMPLE
   Get-SolarStatus -Controller "http://192.168.1.207" -SerialNumber 1234567890
.EXAMPLE
   Get-SolarStatus -Controller "http://enphase.local" -Credentials (Get-Credential "envoy")
.EXAMPLE
   Get-SolarStatus -Controller "http://enphase.local" -CustomPassword 'MyCustomPassword'
