This is product description of the inverter 10 KW-20KW From China
Grid tie inverter for PV-system and wind power system;
With modules design, each module connected in parallel and output;
With accurate and quick MPPT function;
With CE, VDE, ISO9001 certificate;
Grid Tie Inverter is the core facility of solar power plant and wind turbine plant. To make sure the power plant can run stability, it highly require for the reliability of the grid tie inverter. For the scurviness environment of the solar and wind turbine, the stability of DC supply is very bad, that more require to consummate the defencive function of grid-connected inverter and strong capability to resist all kinds of impact.
OUYAD grid-connected inverter, with top-ranking technology, is developed by our experienced engineers. Since put into production for one year, has exported a great deal to Sweden, England and Germany. ( mainly 1KW, 2KW, 3KW, 5KW, 10KW, 15KW, 20KW, 60KW, 100KW) up to now, there are still zero defects.
Grid-connected Inverter Characteristics:
1. controlled by CPU, to keep the stability of the unit;
2. inverter grid-connected output, can follow up the utility grid in millisecond, completeness synchronization to the utility grid.
3. when utility grid test by inverter in three seconds is normal, grid-connected inverter start to work, make sure the inverter will not damage by frequent wave
4. it will lock the unit automatically in less than 10ms when the utility grid interrupted or over-voltage or under-voltage
5. protection against short-circuit and overload
6. output power invariableness. ( normal DC voltage )
7. when wind power or solar power shortage, DC voltage drop, grid-tie inverter output power will reduce, when DC over low achieve inverter DC protect point, inverter will automatically lock and stop work, when DC restores, it will start the unit automatically again,
8. when wind power over-voltage ( such as typhoon), or solar intensity over strong, DC over-voltage, inverter will automatically lock itself, when DC restores, inverter will start to work automatically again
9. communication ports: RS232, RS485, USB ( optional )
10. DC to AC high transfer efficiency up to 90% ---- 96%
