Electrical power control devices and related methods

An electrical power control device, comprising:

• a main relay coupled to an input power connection;
• a main power connection for transmitting electrical power from the main relay to a disconnect panel;
• an auxiliary power connection for transmitting electrical power from the main relay to an auxiliary device;
• an auxiliary relay coupled to the auxiliary power connection;
• an input current sensor configured to sense an input electrical current flowing through the input power connection;
• a main current sensor configured to sense a main electrical current flowing through the main power connection;
• an auxiliary current sensor configured to sense a second electrical current flowing through the auxiliary power connection;
• and
• a data collection and control module coupled to the main relay, the auxiliary relay, the input current sensor, the main current sensor, and the auxiliary current sensor, wherein the data collection and control module is configured to selectively open and close the main relay and to selectively open and close the auxiliary relay depending on whether the auxiliary device functions as a current load or a current source.

A method of forming an electrical power control device, the method comprising:

• coupling a main relay to an input power connection;
• coupling a main power connection to the main relay for electrically connecting to a disconnect panel;
• coupling an auxiliary power connection to the main relay for electrically connecting to an auxiliary device;
• coupling an auxiliary relay to the auxiliary power connection;
• and
• coupling a data collection and control module to the main relay and to the auxiliary relay such that the data collection and control module is configured to selectively open and close the main relay and to selectively open and close the auxiliary relay depending on whether the auxiliary device functions as a current load or a current source.
