The device does not generate power itself for the load sharing and therefore does not disturb the load sharing of the generators on the both sides of the device. The device can be seen as a gate between the digital communication line and the analog communication line. The device simulates load situation of the generator/s connected to the digital communication line for load sharing with other generator/s connected to the analog communication line, and similarly it simulates load situation of the other generator/s connected to the analog communication line for load sharing with the generator/s connected to the digital communication line.

  • Patent number: 9602023
    Abstract: The present invention provides an improved grid connected solar micro-inverter. The solar micro-inverter is provided with a single processor that performs both the functions for the control of the micro-inverter and runs the application program associated with it and implements a communication modem for connectivity to the grid or to the Internet cloud. The solar micro-inverter therefore needs only a single processor to perform both the micro-inverter control and modem communication functions, resulting in cheaper and smaller system implementation.

  • Patent number: 9562520
    Abstract: The present invention provides an integrated system for the combined purpose of electricity generation and water treatment and biofuel production. The configuration combines complementary sub-systems whereby outputs from one system are used as inputs to another creating a positive feedback mechanism that significantly increases system efficiency and output. Compensatory mechanisms between system components create a natural hedge in energy and water production against temporal variation in solar insolence levels. Secondary benefits of the invention may include carbon abatement, ground water improvements, and land regeneration.
