Inverter Programming Settings for an AC Coupled System
In an AC Coupled system, the only recommended system setup is a Grid-Tie with Battery Backup
application. During normal system operation, this setup allows for the coupled grid-tie inverter(s) to power
the home’s loads and sell excess energy to the grid, while the batteries typically remain fully charged. In the
event of a grid failure while the sun is shining, the coupled grid-tie inverter(s) continue to produce power,
and local loads* are powered with solar PV and/or batteries. In the event of a grid failure while no solar
power is available, the batteries discharge to power local loads*.
*Local loads are those circuits on the inverter’s AC distribution panel; circuits that are located on the home’s main
house panel are not considered local loads.
In an AC Coupled system operating normally, power from the coupled grid-tie inverter(s) passes through
the Conext Mini PDP to the grid. Therefore, the Conext XW Pro or XW+ inverter’s
Sell parameters are not
used and
Sell remains as its default value of [Disabled].
In addition to the pre-programmed settings outlined in Table 3.0, ensure that the following parameters are
set in an AC Coupled / Grid-Tie with Battery Backup system:

Inverter Programming Settings for a DC Coupled System
DC Coupled Scenario A: Maximize Renewable Energy Self-Consumption
Enable Grid Support to discharge the batteries to a programmed value before the connected grid is
introduced to the renewable energy system to assist with supporting local loads.
