Power management devices and kits including the same

A power management device comprising:

• a line power input;
• a line power output;
• an inverter in communication with one or more DC power sources, the inverter adapted and configured to receive DC power from a DC power source and output line power;
• a DC transformer in communication with the line power input, the DC transformer adapted and configured to change line power to DC power;
• a first relay;
• a second relay;
• a third relay;
• a sump pump;
• a first timer programmed to periodically interrupt a flow of electricity from the line power input;
• a second timer programmed to periodically cause the sump pump to run regardless of whether a float switch is triggered;
• a sensor programmed to detect whether vibrations indicative of operation of the sump pump occur;
• and
• an alarm programmed to generate an alert if the sensor does not detect vibrations when the second timer periodically causes the sump pump to run;
• wherein:
• if line power is provided via the line power input:
• the first relay is adapted and configured to electrically couple the line power input to the line power output;
• the second relay is adapted to deactivate the inverter;
• and
• the third relay is adapted to electrically couple the DC transformer to the one or more DC power sources;
• and
• if line power is not provided via the line power input:
• the first relay is adapted and configured to electrically couple the inverter to the line power output;
• the second relay is adapted to activate the inverter;
• and
• the third relay is adapted to disconnect the DC transformer from the one or more DC power sources.
