Wind-Solar Hybrid Inverters


Grid-tie wind-solar hybrid inverter converts the variable direct current to alternating current. Besides, it can control and modulate frequency, voltage, current, phase, active power, reactive power and synchronization of alternating current.
According to the characteristics of wind and solar power generation system, grid-tie wind-solar hybrid inverter employs main loop topology structure mode (DC voltage booster > inverter output). This structure adopts a unique triple booster circuit which has high working efficiency (95% to 98%), able to provide stable direct voltage to subsequent conversion. Grid-connected inverters are used for UPS, urban public transportation system, transducer, and so on.

Performance :

1. At the input end of grid-tie wind-solar hybrid inverter, fully-controlled PWM rectifying mode is used. This mode enables power factor to reach 0.99, greatly increasing effective outputs of wind power generator. However, it is only suitable for inverters (the power is more than 30 Kw).
2. Grid-connected inverters are featured by electric supply/inverter output automatic switchover and electric supply charging. On-line UPS output is adopted to avoid instantaneous power-down when the inverter switches electricity output.
3. The optional items as showed in the following table can compensate for limited capacity of wind and solar battery. And they can make the inverter more convenient.
4. When inputting very high voltage, grid-tie wind-solar hybrid inverter employs dynamic power divider and MPPT control mechanism to shunt some voltage for subsequent power supply. This to a great extent explores power supply capacity of wind and solar energy. Compared with that of other controllers and inverters of the same capacity, the output of grid-tie inverter is 10% to 15% higher.
5. It can make use of more than 35% to 45% effective power.
6. Grid-tie wind-solar hybrid inverter is featured by low construction cost, high efficiency, excellent performance and small size. It possesses features of low fault rate, light weight and is easy to use as well.
7. Various flexible remote/short network, optical fiber and communication interface (including RS-232/485/CAN2.0) can conveniently link to upper computer and achieve remote control.
8. Grid-tie wind-solar hybrid inverter is equipped with built-in multistage electric filter and lightning arrester to avoid lightning and high pulse. Thus, it is suitable for high-end communication equipment.
9. The conversion efficiency is over 95% and the distortion degree is as low as less than 3%.
10. Overvoltage, undervoltage, leeway and other input control protections are used to ensure wind power generator to work stably.
