ups solar power is the use of solar cell modules directly

Solar power is the use of solar cell modules directly into electrical energy. The solar cell module (Solar cells) is the use of semiconductor materials properties to achieve solid three phase online ups  device electronics PV conversion, in the vast areas without electricity network, the device can be easily implemented as user-powered lighting and life, ups solar power is the use of solar cell modules directly some developed countries but also with the regional power grid grid achieve complementarity. From the perspective of the current civilian, in the study of foreign technology matured and begun industrialization is "PV - Building (lighting) integration" technology, industrial ups system  but mainly applies to domestic research and production areas without electricity for lighting small household solar power systems. Solar power system include: solar modules (array), controllers, batteries, inverters, lighting loads and other components that user. Wherein the solar cell module and a battery as a power supply system, a controller and an inverter for the control and protection system, the load to the system terminal. Solar cell and battery components of the system power supply unit, so the battery performance directly affects system performance characteristics.

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.
