Connecting to an Existing AC Circuit
You can plug loads directly into the AC receptacle on the front panel of
the PROwatt 3000. However, the receptacle’s circuit breaker limits output
power to 1700 watts (15 amps). To obtain maximum output power, you
need to connect the inverter to an AC circuit and then plug loads into the
receptacles connected to that circuit.
AC Wiring Precautions
If you are going to connect the inverter to existing AC wiring, observe the
following precautions when installing and operating the inverter.
Complete the AC wiring before installing the DC cables.
Maintain correct wiring polarity.
A modern 115 volt AC wiring system has three color-coded conductors:
• black = line (“hot”)
• white = neutral (“common”)
• green or bare = ground
Screws on terminals are typically color-coded as follows:
•brass = line
• silver = neutral
• green = ground
Do not connect the PROwatt 3000 and another AC source (such as a
generator or utility power) to the AC wiring at the same time.
The PROwatt 3000 will not operate if its output is connected to AC
voltage from another source, and potentially hazardous or damaging
conditions may occur. These conditions can occur even if the inverter is
switched off.
WARNING: Electrical Shock Hazard
Complete the AC wiring before installing the DC cables.
Connecting the DC cables to the batteries and the inverter
energizes internal components regardless of the position of the
On/Off switch.
