Xantrex Technology PROwatt 600 User Manual

Connecting DC Cables

10

The chassis ground terminal must be connected to a 
grounding point, which varies depending on where you 
install the PROwatt 600. Follow the guidelines that 
correspond to your type of installation.

Connect the 

 screw to the vehicle’s 

chassis using 8 AWG copper wire (preferably with green/
yellow insulation).

Connect the 

screw to the boat’s DC 

grounding bus or the engine’s negative bus using 6 AWG 
copper wire that has insulation rated at 90º C.

(residential, for example). Connect the 

 

 screw to your system’s DC grounding point 

using 6 AWG wire. The system’s grounding point will 
usually be the AC service entrance grounding point or a 
separate ground rod. For a solar PV (photovoltaic) 
installation, this is usually the same ground rod used to 
ground the PV array.

Proper cables and wiring are essential to effective operation 
of the PROwatt 600. Because the PROwatt 600 has a low 
voltage, high current input, low-resistance wiring between 
the battery and the inverter is essential to deliver the 
maximum amount of usable energy to your load.

Deviating from these guidelines will cause excessive voltage 
drop or melting of the cable and/or connectors. The inverter 
may also shut down or fail to operate some loads.

•

Make sure each cable between the inverter and the 
battery is no longer than 4 feet (1.2 m).

•

Use 4 AWG copper (90º C insulation rating).
