Modular DC cogenerator systems

An emergency power system comprising:

• DC electrical control means for receiving, singly and together, a source of AC electrical power and least one low voltage DC power source;
• said DC electrical control means capable of receiving DC electrical power from first and second sources simultaneously and delivering DC electrical power to an output for use by a load requiring DC power;
• said DC power system means converting said AC electrical power to DC electrical power and controlling and distributing said DC electrical power to said output;
• said first source of DC electrical power comprising storage battery means for providing standby DC electrical power to said DC power system means, said DC power system maintaining said storage battery fully charged for use at peak loads when the DC output electrical power is insufficient to meet the DC load;
• and said second source of DC electrical power being cogeneration means for generating and delivering DC electrical power to said DC power system when there is an AC power outage, said cogeneration means producing and delivering waste heat for use of an external load requiring said heat.

An emergency power system comprising:

• DC power system means capable of receiving AC electrical power and converting said AC electrical power to supply power to charge, and keep charged, a low voltage storage battery;
• said DC power system means also capable of receiving DC power from a DC generator means;
• said DC power system means supplying DC power to an inverter which supplies connected AC loads during an AC power outage;
• and,
• said DC generator means being sized to supply only average AC loads with a small margin to keep said storage battery charged, wherein peak AC loads are supplied by said storage battery.
