Directing or modulating electrical power drawn by one or more loads from a solar photovoltaic module array while maintaining a buffer margin

A method of prioritizing power between a plurality of devices, the method comprising:

• comparing available power from a power source against power needs of a main device and one or more secondary devices, wherein the power source includes a solar photovoltaic module array electrically coupled to the main device;
• directing a portion of the available power to the main device;
• diverting an unused portion of the available power to the one or more secondary devices;
• and
• maintaining a buffer margin between (1) the available power and (2) the portion of the available power directed to the main device and the unused portion of the available power diverted to the one or more secondary devices.

A control assembly configured to modulate electrical power drawn by one or more devices based on available power, the control assembly comprising:

• a monitoring module configured to continuously measure available electrical power that is available from a power source;
• and
• a control module configured to
• selectively direct electrical power to the one or more devices based on the available electrical power, the control module selecting which loads to turn on based on power requirements of the one or more devices in relation to the available electrical power;
• and
• maintain a buffer margin between the electrical power directed to the one or more devices and the available electrical power.

A refrigeration device assembly, comprising:

• a solar photovoltaic module array;
• a refrigeration device electrically coupled to the solar photovoltaic module array;
• a monitoring module configured to continuously measure available electrical power that is available from the solar photovoltaic module array;
• and
• a control module configured to
• modulate electrical power drawn by one or more loads from the solar photovoltaic module array based on the available electrical power, the control module selecting which loads to turn on based on power requirements of the one or more loads in relation to the available electrical power;
• and
• maintain a buffer margin between the electrical power drawn by the one or more loads and the available electrical power.
