3kwsolar panel grid tie inverter / solar on grid tie inverter working on grid and off grid system (can connect battery)       if you want to get more information,also can contact us directly!  Mobile:8613690853732     Skype:candyluo1989     email:candy at tanfon.com  Factory introduce: Foshan Tanfon Energy Technology Co.,LTD which a manufacturer for solar systm products,wind turbine system products.   why our inverter is low voltage design? A:becouse our inverter have perfect function that can working get the power to the grid ,also can take the load directly. inverter have CE dertification; 2 year warranty; ship the free parts for service; (our factory sincerely hope can have good cooperation with you in the feature)    1)base on all numeral controller technology ,have many kinds of intelligentize controller function. 2)the system used advanced form technology,reduce on grid current’s aberrance. 3)have perfect protect function,the highest dependability of the system. 4)have CPU look forby the unit technology,and maximun advance the power of the system. 5)have MPPT function,how many power from wind or solar ,the unit will get the power to the grid . 6)for transformer technique,make100% copper transformers materials 7) our on grid inverter have CE,G83 AS4777 certificate sales all over the world 8)Start way: As long as wind turbines or solar panels from the issue of an electric, it  can automatically get the power to the grid, do not need to manually boot. Also directly with a load, working like off grid inverter .
