Do I need a grid-side meter with the Power Dock Pro?
As a Main Panel: No. If the Power Dock Pro is your main service panel, no grid-side meter is needed.
As a Sub-panel: Yes. If installed downstream of another main panel, a grid-side meter must be installed in the main panel and connected to the Power Dock Pro via an RS485 cable.
