I ordered a standalone Enphase Envoy but instead got shipped an IQ Combiner box with built-in Envoy. The supplier said to just keep it rather than exchange it. I had already installed a subpanel and it was less work to remove the Envoy from the IQ Combiner box and install it in a different enclosure rather than rip out my subpanel and install the IQ Combiner in its place. If anyone could use an IQ Combiner WITHOUT the Envoy installed, you can have it for the cost of shipping or pick up in SE WI.
