 The Second Generation of Grid Tied Inverter

On grid inverter used in wind turbine system and solar system.the mostly act on :when the power from wind or solar.through on grid inverter for used immediacy also can from on grid inverter to mains,need't battery,save on cost, diminution spoilage.
feature:
used the up to the minute CPU for Eupec,the efficiency of the systems will be high,with LCD display
base on all numeral controller technology ,have many kinds of intelligentize controller function.
the system used advanced form technology,reduce ongrid current's aberrance.
have perfect protect function,the highest dependability of the system.
have CPU look forby the unit technology,and maximun advance the power of the system.
can running for many pcs inverter parallel connection.
have MPPT function,how many power from wind or solar ,the unit will get the power to the grid .
the second generation for the PCB DC voltage are from 12V---450V,so can design small power for 12V DC voltage,and will get more power to grid.
Start way: As long as wind turbines or solar panels from the issue of an electric, it  can automatically direct and to the power grid, do not need to manually boot.
Also directly with a load, working like off grid inverter .
