Where possible, it is generally recommended to install smart PV inverters with frequency-
Watt capability for AC coupled systems. However, operation with legacy PV inverters can
be considered for grid-tied applications with less frequent outages.
Installation Notes
ACBreaker Requirement
Each PV inverter that is connected to the AC Output (load) of the Conext XW+ requires its
own AC breaker. Although there is room to add breakers for the PV inverters directly into the
Conext XW+ Power Distribution Panel, it is easier to install the breakers for AC coupled PV
inverters in the critical load panel. If installing the PV inverter breakers in the Power
Distribution Panel, refer to the Conext XW+ Installation Guide (document part number: 975-
0239-01-01). The sub-panel may also contain load breakers.
To install an AC-Coupled system:
1. Install one or more battery inverters according to the procedures outlined in their
respective Installation Guides.
2. Install one or more PV inverters according to their Installation Guides, with the following
exception: instead of connecting the PV inverter's AC output to the main AC panel,
connect it to the Conext XW+ AC critical load panel.
