SOLAR ENERGY POWER CONVERSION SYSTEM
A power conversion circuit is used in a solar array suitable for, e.g., roadside adjacent installation. The power conversion circuit includes an inverter with a first stage electrically coupled to one or more solar panels. A third stage of the circuit has a DC to AC converter that provides less than a 50 VAC load voltage to a load, and a second stage that is coupled between the first and third stages and provides an isolated electrical power coupling therebetween. A sync interface communicatively couples a controller to other controllers dedicated to one or more other respective inverters of the solar array via a sync signal. The controllers synchronize the third stages of the inverters via the sync signal. The third stages of the inverters are coupled in series to provide a load output voltage.

Inverter
An inverter for a photovoltaic system includes a substantially planar baseplate having a front and a rear, wherein the rear forms an outer rear wall of the inverter, and having at least one platform-like elevation that rises in the direction of the front of the baseplate. The inverter also includes a printed circuit board having one or more heat-generating components mounted thereon, wherein the printed circuit board is installed on the baseplate such that the one or more heat-generating components are arranged on the printed circuit board in the region of the platform-like elevation and are in thermal contact with the platform-like elevation. The inverter further includes a potting compound that fills a space on the front of the baseplate and surrounds at least partially the printed circuit board, and a cover arranged on or in the potting compound that adjoins the baseplate, so that the baseplate and the cover surrounding at least part of the potting compound form a housing. The inverter also includes at least four DC connectors that are arranged in pairs on at least one of the lateral end faces of the housing and at least part of which is cast in the potting compound, and an AC connector that is arranged on one of the lateral end faces of the housing, wherein electrical contacts of the AC connector are connected to the printed circuit board.

PHOTOVOLTAIC MODULE AND PHOTOVOLTAIC SYSTEM
A power converter box and at least one junction box are integrated on a backplane of the photovoltaic module as a whole, and there is a cable for connecting the power converter and the junction box. In this case, relative to the conventional technology in which a junction box is independent of a power converter, a length of a cable used when the junction box and the power converter box are taken as a whole is shorter than a length of a cable used in the conventional technology. In this case, compared with the conventional technology in which a cable is connected to an independently placed power converter, the power converter only needs to establish a connection relationship by using a solder ribbon, a circuit board cable, and the like with low costs, so that production costs are low.
