Methods, devices, and systems for controlling energy generation interactions that bypass the grid may be provided. Flow control devices may be directly connected with one another independent of electrical connections to the utility grid. In some examples, the direct connections between the devices may enable sharing of power, controlling power flow over the direct connections, and/or recording relative power flows between the devices.
