Outback FXR/VFXR Renewable Series Installation Manual

Installation
32 900-0166-01-00 Rev B

The second inverter must be programmed as
L2 Phase Master
. It must be connected to port 7.

All overcurrent devices must be sized for 60 Aac or less. All wiring must be sized for 60 Aac or more.

All output circuit breakers must be sized appropriately for loads and inverter power.

The AC input (generator or utility grid) must be a split-phase source of the proper voltage and frequency.

When wiring the AC source to the inverters, local codes may require the inverter circuit breakers to be
located at the bottom of the main panel. This prevents overloading of the AC bus.
NOTE
: The FW-X240 and similar transformers are not used for load balancing of stacked FXR inverters.
