Operating Several Loads at Once

Operating Several Loads at Once
If you are going to operate several loads at the same time, turn them on
separately after you have turned the inverter on. This will ensure that the
inverter does not have to deliver the starting current for all the loads at
once.
Resetting the AC Circuit Breaker
If you are powering loads using the AC receptacle on the PROwatt 3000’s
front panel, the built-in circuit breaker limits the output power to 1700
watts (15 amps). If the breaker trips while you are powering loads from
this receptacle, reduce the size of the load. Reset the circuit breaker.
Reading the Front Panel Indicators
Battery Voltage Indicator
The battery VOLTS indicator shows the voltage at the input terminals of
the PROwatt 3000. At low input currents, this voltage is very close to the
battery voltage. At high input currents, this voltage is lower than the
battery voltage because of the voltage drop across the cable and
connection.
• During operation, the voltage should remain in the green area.
• If voltage goes into the top or bottom red area, the inverter may shut
down.
Battery Current Indicator
The AMPS indicator shows the current that the inverter is drawing from
the battery. It does not indicate current drawn by other loads also
connected to the battery.
• For long-term operation, the current should remain in the green area.
• Short-term operation is possible with the current in the yellow area.
• If the current rises to the red area, the inverter reduces its output
voltage to protect itself and will shut down soon after.
