Operating Limits
Power Output
The Prowatt 1000 will deliver up to 1000 watts or 8 amps continuously,
depending on input voltage and ambient temperature. The 1000 watt
capability is reached when ambient temperature is less than 68º F (20º C)
and input voltage is between 12 and 13 volts.
The inverter will deliver more than 1000 watts or 8 amps for
approximately 10 to 15 minutes. The inverter must cool for 15 minutes
before it can resume operation above 1000 watts.
The wattage rating applies to resistive loads such as incandescent lights
while the current rating applies to reactive loads such as motors.
Input Voltage
The input voltage limits are shown in the following table.
Operating
Condition Voltage Range Comment
Normal 10 V–15 V
Peak Performance 12 V–14.5 V
Low Voltage Alarm Voltage is
10.7 V or less
The audible low battery alarm sounds
and the
VOLTS
indicator is in the
lower red area.
Low Voltage
Shutdown
Voltage is less
than 10 V
The inverter shuts down to protect the
battery from being over-discharged.
High Voltage
Shutdown
Voltage is 15 V
or more
The inverter shuts down to protect
itself from excessive input voltage.
The
VOLTS
indicator is in the upper
red area.
Note:
Although the PROwatt 1000
incorporates over-voltage protection,
it can still be damaged if input voltage
exceeds 16 V.
Unit restarts after low
voltage shutdown
The inverter will not restart unless the
battery voltage is acceptable for
running the load.
