The practical application of UPS solar energy

UPS for large-scale solar photovoltaic power plant systems, UPS solar energy in many parallel PV strings are connected to the same centralized inverter DC input terminal, the general use of the three-phase power switching power supply power modules, switching power supply smaller power field effect transistors, while the DSP switch controller to improve quality of the output power, making it very close to a sine wave current. The maximum power of the system is characterized by high and low cost solar UPS. But the influence of PV string matching and partial shading, resulting in efficiency and power capacity of the entire PV system. Switching power supply while the Offline ups system reliability by poor working conditions of a photovoltaic cell groups affected. The latest research is the use of space vector modulation control, as well as the development of new topology connected inverters, UPS solar energy in order to achieve high efficiency under partial load conditions. UPS focused on solar inverters, Uninterrupted power supply switching power interface box can be attached to a photovoltaic array, photovoltaic panels on each string string monitoring, such as where there is a set of strings is not working properly, the system will put this information on to on the remote controller, and can stop this bunch of work by remote control, so as not to because of the failure of a string of PV strings and impact of the work and reduce the energy output of the PV system.
