Abstract: A isolated-type hybrid solar photovoltaic system contains: a solar cell having a peak power value of the solar cell, a battery having a power capacity and a discharge depth, a controller, at least one independent inverter, at least one relay, at least one AC load, at least one load measuring element, at least one load transmission wire, a AC grid power, and a microprocessor. The controller is electrically connected with the solar cell, the battery, the microprocessor, and the at least one independent inverter. The at least one relay has a first connecting point electrically connected with the at least one AC load and has two second connecting points electrically connected with the AC grid power and AC output end of the at least one independent inverter. The at least one relay further has a driving connection point electrically connected with an output end of the microprocessor.

Abstract: A high-performance diffusion multiple-effect distillation system, which comprising: a few distillers, a heating device and a water make-up device; said distiller is composed of several laminar distillation sheets, with one surface taken as a condensing surface, and the other surface attached with an evaporating sheet; a collecting ditch is set below the condensing surface; and the periphery of the distillation sheets is provided with a supporting structure; the heating device is provided with several heating surfaces; the heating surface and the condensing surface of corresponding distillation sheet have a good thermal contact, the water make-up device is provided with at least a water tank filled with water to be distilled and at least a water make-up body.

Abstract: The present invention is related to the apparatus for driving the light emitting devices with different colors. The input powers of the light emitting devices are measured and controlled by a feedback control system to maintain constant, and by setting different power inputs to the different light emitting devices different stable colors are produced.
