Xantrex XW MPPT Solar Charge Controller
The
Xantrex XW photovoltaic Solar Charge Controller (XW SCC) tracks the electrical
maximum power point of a PV array to deliver the maximum available current for
battery charging. While charging, it regulates battery voltage and output
current based on the full amount of energy available from the PV array and
battery state-of-charge.
The XW SCC incorporates a dynamic Maximum Power Point Tracking (MPPT) algorithm
designed to maximize energy harvest from the PV array. MPPT continuously adjusts
the operating points of the array for maximum power output. It does not stop
energy harvest to sweep the array like some other competing products. This
feature is beneficial all sunlight conditions, especially in areas with fast
moving cloud cover and quickly changing solar conditions.

The XW SCC can be used with 12, 24, 36, 48, and 60-volt DC battery systems.
Because the MPPT technology along with the XW’s ability to efficiently convert
higher PV array voltages down to battery array voltages you can now run your
PV array in series with voltages up to 150 Vdc. This allows for better
performance during marginal light and lower line transmission loss from PV
array to charge. The XW Solar Charge Controller can be installed (in single or
multi-unit configurations) with Xantrex XW Hybrid Inverter/Charger(s) or can
be used in other solar energy systems where a solar charge controller is
required.
Standard features of the Solar Charge Controller include:
-
Maximum Power Point Tracking (MPPT) delivers maximum available power from PV
array to battery bank
-
Integrated PV ground-fault protection
-
Ultra-reliable, convection-cooled design does not require a cooling fan −
large, aluminum, die-cast heat-sink allows full output current up to 45°C
without thermal de-rating
-
Selectable two or three-stage charging algorithms with manual equalization to
maximize system performance and improve battery life
-
Configurable auxiliary output
-
Two-line, 16-character liquid crystal display (LCD) and four buttons for
configuration and system monitoring
-
Input over-voltage and under-voltage protection, output over-current
protection, and back-feed (reverse current) protection (warning and fault
messages appear on LCD when unit shuts down as a protective measure)
-
Over-temperature protection and power derating when output power and ambient
temperature are high
-
Battery Temperature Sensor (BTS) included − automatically provides
temperature compensated battery charging
-
Xanbus™-enabled network communications protocol (developed by Xantrex)
-
Communicates settings and activity to other Xanbus™-enabled devices, such as
the XW Hybrid Inverter/Charger, the XW System Control Panel (XW SCP), XW
Automatic Generator Start (XW AGS), and other XW Solar Charge Controllers.
