Can I plug the Envoy into a power strip?

Envoy

Some Enphase Envoy models must be wired for power, while others can be plugged in to a wall outlet. Do not plug the Envoy into a power strip, surge protector, or uninterruptable power supply (UPS). The surge suppression or filtering within these devices impede power line communication performance. Also, do not plug a power strip into the same outlet that the Envoy is using. The surge suppression or filtering components of a power strip may still interfere with communications if they are near the Envoy.

Plug the power chord into a dedicated outlet as close to the solar-fed subpanel as possible.
