The Future
The Conext XW grid interactive feature-set is a key enabler for residential self consumption systems and utility demand
response systems. Conext XW supports both AC Coupled and DC Coupled self-consumption models. Communications
functionality allows utility operators remote access to Conext XW. Conext XW is compatible with Lithium Ion battery packs.

Commercial Load
Conext XW integrates with commercial building switchgear to seamlessly and instantly convert power from battery reserves to maintain operation
of critical loads such as security, data and communication systems, as well as pumps and machinery when the power grid fails or browns out.
When utility power is readily available, the Conext XW will keep the battery bank fully charged, ready for the next time.
Conext XW systems can be scaled up to 36kW and configured for single-phase, split-phase or three-phase power. The Conext XW easily
integrates with a generator for extended backup time.

In addition to providing backup power for commercial operations, the Conext XW easily integrates Photovoltaic (PV) power reducing business
dependency on utility power by offsetting consumption and increasing the return on investment. Conext XW can also manage load shifting to
avoid expensive time-of-day electricity charges. Integrating PV power in regions with weak or intermittent grid power will allow businesses to
operate for extended periods of time without grid power.
Conext XW systems can be scaled up to 36kW and configured for single-phase, split-phase or three-phase power. The Conext XW easily
integrates with a generator to further increase business operating time when the grid is down. The control and monitoring capabilities of the
Conext XW system provides businesses with management information to ensure dependability is maintained and systems operate as they should.

Residential Load
Wherever independent off-grid power is required for the operation of remote farms, monitoring stations, telecom towers or work camps, the
Conext XW is a cost effective replacement for a diesel generator.
If PV production is insufficient or unavailable to meet demand, a generator can be integrated by the Conext XW and managed by the Automatic
Generator Start (AGS) module to assist with loads and recharge batteries as required. For existing off-grid diesel generator power systems,
integrating a Conext XW will facilitate the decrease in both generator run time and corresponding fuel costs.
The control and monitoring capabilities of the Conext XW system provides power management information for operators and peace of mind that
remote property is secure and power dependent systems are operating as they should.

Homeowners embrace the Conext XW because it allows for fully-automated, hassle-free, backup power.
Unlike a plug-in backup power pack or portable generator, the Conext XW inverter/charger is integrated into the electrical system and seamlessly
converts power from battery reserves to support critical loads such as pumps, security systems, refrigerators and electronics in the event of a power
outage or brown-out. When utility power is readily available, the XW will keep the battery bank fully charged and ready for the next grid failure.

In addition to providing residential backup power, the Conext XW’s ability to easily integrate PV power will help reduce household dependency on
utility power by offsetting consumption.
Conext XW supports DC coupled and AC coupled grid-tie systems. Conext XW’s grid-interactive feature also provides a means to sell excess
power back to the utility, qualifying homeowners for locally available feed-in tariff programs and green tax credits, further increasing the return on
investment. The Conext XW easily integrates with a generator for extended backup power.

For off-grid home owners, Conext XW inverter chargers provide AC power from batteries. Conext XW systems Maximum Power Point Tracking
(MPPT) solar charge controllers enable PV modules to directly charge batteries. The pure sine wave output and high surge capabilities of Conext
XW inverter/chargers start and run pumps with ease, enabling key water and sewage systems, and assisting smaller generators in starting difficult
loads. The Conext XW can integrate a fuel based generator enabling cost effective hybrid off-grid power solutions.
The control and monitoring capabilities of the Conext XW system provides off-grid home owners with management information to ensure

Community Loads
Conext XW is adaptable and scalable, powering off-grid communities around the world and helping them qualify for renewable energy funding
programs to establish reliable, high-quality localized community power plants. By coupling to renewable PV energy generation through the
DC system, Conext XW delivers a more affordable AC power solution than traditional off-grid systems that rely on power supplied from diesel
generators alone.
Conext XW community based off-grid systems scale up in 36 kW clusters and are expandable at any time. Conext XW supplies a standard
AC voltage grid, enabling communities to not only benefit from the low cost and wide variety of common AC appliances and tools, but also
from the continuously declining cost of renewable PV power generation. Conext XW will also integrate diesel generators into a hybrid off-grid
system increasing the flexibility and reliability of the entire system while still reducing community dependence on the ever increasing cost of
fuel generators.
Remote system monitoring and management is available for the supervision of Conext XW and supporting system components.
The Schneider Electric Conext XW system is the One Solution for grid-interactive and off-grid, residential
and commercial, solar and backup power applications.
