Prioritizing and Managing Energy Sources with Advanced
Features
The Conext XW+ can be programmed to control how and when to use utility
power as well as external DC sources of energy such as batteries and solar
charge controllers. Advanced features allow management of peak loads, time-of-
use billing and self consumption.
Grid Support
The grid support mode allows the Conext XW+ to support local loads by
converting excess capacity from external DC sources connected to its battery
bank. Examples of external DC sources are solar charge controllers and
batteries.
For grid support to function Grid Support must be enabled on the Setup menu
and the battery voltage must be above the Grid Supp Volts setting. To export
energy to the utility grid (AC1) Conext XW+ sell mode must be enabled.
Grid Support enabled, Sell disabled In this mode, available excess DC power
is converted and used to power local AC loads attached to the inverter output.
No power is exported on AC1 (grid) to the utility. If the local AC load demand
exceeds the available power from the external DC sources, power is then drawn
from the utility grid (AC1) to support the load. However, if the local AC load
demand is less than the power available from external DC sources, the net
