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.
ADVANCED CONFIGURATION HAZARD
Advanced menu settings should be used by qualified personnel only.
Three phase operation should be configured by qualified personnel only.
Consult with the local utility before enabling Conext XW+ sell mode or grid
support functions.
Do not change these settings unless you are under the supervision and
direction of qualified personnel.
Failure to follow these instructions can result in death or serious injury.
Note: Grid support and sell functions are modes of operation that are subject to
local and/or national grid interconnection requirements in most jurisdictions. It is
the responsibility of the installer and system operator to ensure that all applicable
procedures and technical requirements are complied with before turning on
either of these modes. The interconnect codes and standards with which the
Conext XW+ complies are listed in Chapter A, "Specifications".
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.
There are two modes of operation within Grid Support.
• Grid Support enabled, Sell disabled
In this mode, available excess DC power is converted and used to power
local loads. No power is exported to the utility. If the local load demand
exceeds the available power from the external DC sources, power is then
drawn from the utility to support the load. However, if the local load demand
is less than the power available from external DC sources, the net excess
power from the external DC sources is not converted and hence not used.
