the ConnectDER meter collar

Through a new partnership with Infinite Invention, Green Mountain Power offers the ConnectDER meter collar for solar contractors. The ConnectDER enables rapid connection of grid-ready distributed energy resources (DERs), especially solar photovoltaic systems (PV) by creating a connection point to a collar that installs between a residential electric meter and a meter socket.

The ConnectDER is available for installation in GMP's service territory.  It reduces the cost of a residential solar project by $500-$1,000. Installers can purchase the 20-60 amp ConnectDER from GMP for $365 and the 70-80 amp units for $425.
