General New SI solar inverter complies with stand-alone power inverter is design for family. When utility AC power cut off, the transfer relay is de-energized and the load is automatically transferred to the TSINE series output. Once the AC utility is restored, the relay is energized and the load is automatically reconnected to AC utility. Features ● Large power continuous output for electronic appliances ● Pure sine wave output (THO < 3%) to operate higher-end electronic Equipments. ● DC Star-up. Start by using battery when the AC source is off ● Speed up transfer time and synchronized operation with the AC source at all times that allows the transfer to be interruption-free for sensitive equipments ● Built in advance microprocessor to make friendly interface with user. ● Input power factor correction. ● Powerful charge up ability. ● LED indicators with tri-color display all operation status
