Yiwu solar photovoltaic power inverter runs on this year earlier




Reporters yesterday at the International Trade City District 4 to see the roof, solar photovoltaic power generation system is divided into eight regions, from 8 sub-system structure. The roof of photovoltaic arrays each region corresponds to a control room, each subsystem the control room to install a solar power inverter and a grid-control screen, into an independent, and the nearest outlets for local load power. "A total of 7000 photovoltaic panels, which is currently the largest single roof solar power station." Kun said that the total installed capacity of power generation systems 1.295 MW, with an annual generating capacity of 152 million kWh. Energy conversion process is not complicated, the sunlight in the PV panel, plate inside the polysilicon solar energy can be converted to DC, DC through the inverter, can be turned into 220 volts of alternating current, into the market grid.



On the roof of a small room, the reporter saw one imported from Germany, inverter, solar power, and above a network control panel. According to reports, such as equipment, a total of eight units in four districts in the roof, you can use a computer control, power generation equipment operation can all be displayed on the computer, even in the rest of the world through the Internet remote real-time observation of system performance.



"Examination and approval, installation has been completed." Kun said, because the system used with the "island effect" protection of the inverter, grid-connected power generation should also be equipped with eight current measurement counters. At present the electricity sector is stepping up its customization can be no later than the first half of next year and the grid.
