Protective Functions
1.Overloading Protection: When the power consumption of the appliance/appliances exceed the total power of the solar inverter. It will then revert to the protection state within 20 seconds untill you reduce the load
2.Short circuit protection: If an appliance short circuits. The solar inverter will revert to the protection state untill the appliance is removed.
3.Thermal protection: If the temperature of the solar inverter gets too hot it will revert to the protection state untill it is turned off to cool down.
4.Reverse polarity protection: If connected incorrectly no current will pass through the solar inverter(The hand of the voltage meter will point to the reverse direction)
