OVER TEMPERATURE PROTECTION:
OVERPOWER, SHORT CIRCUIT PROTECTION:
The inverter is also
protected against overheating. It will provide its full rated output up
to the temperature listed in the specification sheet. If it is subjected
to higher ambient temperatures or air circulation is blocked, the
inverter may overheat. If the LOWBATT/THERM buzzer sounds,
immediate action is required or the inverter will shut down. Either
reduce load, or provide more cooling in the immediate environment.
If no action is taken, the inverter will likely shut down within 2
minutes. When the inverter shuts down, the alarm condition will
persist and the cooling fan will continue to run. Since the inverter
has eliminated its load, it will cool fairly quickly. It will automatically
restart when it has cooled sufficiently, and the LOW BATT/THERM
alarm will clear. “105 C internal temperature. Warning buzz 5 C
before shut off”.

The inverter has
three levels of overpower protection. The first
limits peak
instantaneous current. The second system limits absolute power
coming from the module. Both of these circuits act to reduce output
voltage as required, to limit current to a safe level. The overpower
protection circuit will recover instantly if the overpower condition
clears within 3-5 seconds. The third, is short circuit protection. If the
over current condition is so severe that it causes output voltage to
collapse for more than 5 seconds, the inverter will shut down and
not automatically restart. The LED will flash red and the fan will be
on. This requires the user to clear the short circuit safely, and
guarantee that hazardous voltage will not come back on line until
desired. To reset the inverter from this condition, cycle power switch
“OFF” then “ON” again.
inverters will provide peak current (45 A at 117VAC or
22A at 230VAC) or maximum surge (4000W) for 3 seconds when
the inverter
’
s internal temperature is at or below 30
. The output
power is then reduced to 2000W (rated power) for 4 secs.
If the
inverter cannot restore a full sine wave due to overload, the LED will
be red.
If the overload condition does not clear in the 7 secs.
