Protection
Over load When load exceeds 125% or 150% 0r 200% of power capacity,
inverter will shut down 20s or 10s or 5s later, and diagnose
as overload fault with red LED lit.
When load is 100~125%, 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 is short, the system will shut down and the red
LED will be 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.
