When using the system for time-of-use metering, the system should be designed
with a battery capacity large enough to support loads during the entire peak rate
period without reaching the Low Batt Cut Out setting.
Note: If the batteries reach the Low Battery Cut Out setting, the Conext XW+
automatically reconnects to the utility grid to maintain the connected load.
PLS can also be used with time-of-use metering to support self-consumption. In
the self-consumption mode of operation, the Conext XW+ delays Peak Load
Shave mode by a fixed time of 2 hours. This is done by allowing a priority for the
MPPT solar charge controller to charge the battery bank.
This configuration can be selected under the Conext XW+ menu by selecting
Advanced Settings/Advanced Features/PLS DLY 2H=Enabled. The default
setting for PLS DLY 2H is Disabled.
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.
Generator support allows power to be automatically drawn from the batteries to
assist an AC generator on AC2 to support heavy loads on AC OUT (loads that
exceed the available power from the generator).
Generators have a limited output current and it is possible to reach this limit when
operating heavy loads. The Conext XW+ is designed to assist the generator
when heavy current demands load down the generator by supplying additional
power from the batteries.
In addition, the battery charger can reduce its charging current to the batteries
so the combined AC current required for charging and the total load current do
not exceed the capacity of the generator or trip its output breakers or fuses.
For imbalanced loads and small generators, the generator support feature may
be used. When GenSupp Plus is enabled, the Conext XW+ will connect the
center of its transformer to the AC2 input neutral to act as a load balancing
