2.0 INSTALLATION
©2000 Xantrex Technology Inc.
Main Service Panel:
The input to the inverter requires a minimum 60 amp breaker (for each inverter if stacked). This
circuit breaker must be located in the utility service panel.
Sub-Panel:
Loads backed up by the inverter will need to be rerouted from the main service panel to a sub-
panel. This can be done several different ways, depending upon the installation. Always refer to
electrical codes for safe wiring practices.
AC Circuit Breakers:
Always use a properly rated circuit breaker. Depending upon the application, circuit breakers
used to protect the load can be removed from the main service panel and put into the sub-panel
ONLY if the two panels are from the same manufacturer.
DC Disconnect:
Install a DC disconnect breaker or fuse in the positive battery line. This breaker protects the DC
wiring in the event of an accidental short. Size the breaker in accordance with the battery cables.
Switch this breaker OFF whenever servicing the batteries.
Wire Routing:
Determine all wire routes both to and from the inverter and which knockouts are best suited for
connecting the AC conduits. Possible routing scenarios include:
AC Input wiring from the main utility service panel to the inverter/charger
AC Input wiring from the generator to the inverter/charger (if used)
DC Input wiring from the PV array (wind, hydro, etc.) to the inverter/charger (if used)
DC Input wiring from the batteries to the inverter/charger
AC Output wiring from the inverter/charger to the sub-panel
Battery Temperature Sensor cable from the batteries to the inverter/charger (if used)
Remote Control cable to the inverter/charger (if used)
DC Ground from the batteries to an external ground rod
Load circuit wiring rerouted from the main service panel to the sub-panel
Check for existing electrical or plumbing prior to making cuts in the walls. Cut holes in the walls
at appropriate locations for routing wiring/cables.
