Inverter Protection
Over Load:
When load exceeds 150% of power capacity, inverter will shut down after
20 seconds, and diagnose as overload fault with red LED lit.
When load is 105~150%, inverter continuously delivers output power
with a yellow LED lit for warning.
Output Voltage Fault Detection:
When the output RMS (root mean square) voltage is out of operating
voltage range, the inverter unit will diagnose as output voltage high or
low fault.
Inverter Output Short Circuit:
When output RMS voltage is below 40VAC and output RMS current is
over 2A, the system will diagnose as inverter output short circuit fault
with red LED on.
Input Voltage Detection:
When the DC input voltage is out of operating voltage range, the inverter
system will shut down and release visual and audio alarms.
Over Temperature:
When inverter internal temperature rises over 100°C (212°F), the system
will diagnose as over temperature fault with red LED flicker.
