Key protection
Output overload protection
When the load power is more than 120% of rated power, the LCD will indicate the information of over-load, and alarmed by audible,then turn-off output after 1minute delay.
Output in short-circuit protection
In case of output in short-circuit, the LCD will indicate short-circuit,and alarmed by audible,the inverter will turn-off output automatically at the same time.
Output reversed polarity protection
When the inverter input DC voltage polarity reversed, the alarming will alarm, and the inverter will automatically turn off.
Output under-voltage protection
When input DC voltage is under 198V,the LCD will indicate under voltage,alarmed by audible,the inverter will turn-off output automatically.When the voltage back to 242VDC, the output will resume automatically.
