a communication circuit configured to:

in response to a disconnect signal from the DER controller, actuate the whole-building disconnect switch to disconnect the building from the utility grid;

in response to a reconnect signal from the DER controller, actuate the whole-building disconnect switch to connect the building to the utility grid; and

a housing separate from the MSA, the housing enclosing:

a distributed energy resource (DER) disconnect switch; and

a control circuit configured to:

receive an indication, from the communication circuit, of a total current provided to the building; and

based on the indication of the total current, actuate the DER disconnect switch.

12 . The MSA system of claim 11 , wherein the control circuit comprises an energy management system (EMS).

13 . The MSA system of claim 11 , wherein the control circuit is further configured to:

based on the indication of the total current, determine an overcurrent risk; and

in response to determining the overcurrent risk, actuate the DER disconnect switch to disconnect the MSA from the DER controller; and

in response to the total current being below a predetermined threshold, actuate the DER disconnect switch to connect the MSA to the DER controller.

14 . The MSA system of claim 11 , wherein the communication circuit is further configured to:

measure one or more characteristics of the utility grid;

transmit the one or more characteristics of the utility grid to the DER controller, wherein the disconnect signal is received from the DER controller in response to the one or more characteristics of the utility grid.
