solar inverter

48V-3KW inverter introduction; can also make 24V-3KW. 1.Super wide input voltage range:90V-280V 2.Four-steps AVR 3.Powerful charging current:500W up to 15A,1KW-4KW,up to 25A 4.Protection against short-circuit 5.Special overload protection,when it is overload,it will lock the unit automatically, when it restores,it will start the unit automatically again 6.when the mains come,it will start the unit automatically 7.Function that it will change its frequency instantly it is able to drive inductive loads,such as air-conditioner,refrigerator, motor,and so on 8.With RS232,it can realize software control function.
