Off-Grid Wind-Solar Hybrid Inverters

Off-grid wind-solar hybrid inverter converts the variable direct current to a utility frequency alternating current that can be used by local off-grid electrical networks. Basing on the features of wind and solar power generation system, the inverter adopts main loop topology structure mode (DC voltage booster > inverter output). After being boosted, the DC voltage lowers down to charge a battery which can assist power supply when DC input capacity becomes insufficient. This structure uses a unique triple booster circuit featured by very high working efficiency (95% to 98%). Besides, the circuit can provide stable DC voltage to inverter. At present, sine wave power inverters are suitable for UPS (Uninterruptible Power System), urban public transportation system, transducer, etc.

Performance :
1. Off-grid wind-solar hybrid inverter employs fully-controlled PWM rectifying mode which can make power factor reach 0.99. This greatly increases effective outputs of wind power generator. However, this mode is only provided for inverters with power being not less than 30 Kw.
2. It has additional functions, such as electric supply/inverter output automatic switchover and electric supply charging. On-line UPS output is adopted to ensure that off-grid wind-solar hybrid inverter does not power down when overloading.
3. The optional parts as showed in the following table can make up for the shortage of limited capacity of wind and solar battery. And they can make the inverter more convenient.
4. When inputting very high voltage, off-grid wind-solar hybrid inverter uses dynamic power divider and MPPT control mechanism to shunt some voltage for backward stage power supply. The output is 10% to 15% higher than other controllers and inverters with the same level of capacity.
5. It can make use of more than 35% to 45% effective power.
6. Off-grid wind-solar hybrid inverter makes most use of advantages of combination. It is characterized by low cost, high efficiency, excellent performance and small size.
7. It also has features of low fault rate, light weight and is easy to use.
8. 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.
9. Off-grid wind-solar hybrid inverter is equipped with built-in multistage electric filter and lightning arrester to prevent lightning and high pulse. Thus, it is fit for high-end communication equipment.
10. The conversion efficiency is more than 95% and the distortion degree is less than 3%.

The following data serves as reference to know the performance of off-grid wind-solar hybrid inverter.
