Features
The XW Solar Charge Controller (XW SCC) is a photovoltaic (PV) charge
controller that tracks the maximum power point of a PV array to deliver the
maximum available current for charging batteries. The XW SCC can be used with
12-, 24-, 36-, 48-, and 60-volt DC battery systems.
The XW SCC is designed to regulate PV input, but will also work with other DC
sources. The DC source must meet the specifications listed on page A–2.
The XW SCC can be installed (in single or multi-unit configurations) with a
Xantrex XW Hybrid Inverter/Charger or in a stand-alone installation.
Standard features of the XW Solar Charge Controller include:
•
Two- or three-stage charging process, with manual equalization to maximize
system performance and maintain expected battery life.
•
True dynamic Maximum Power Point Tracking (MPPT) to deliver the
maximum available power from a PV array to a bank of batteries. See
“Maximum Power Point Tracking” on page 1–3.
•
Integrated PV Ground Fault Protection (PV-GFP).
•
Convection cooled (no internal or external fan) using aluminum die-cast
chassis and heat sink.
•
60-amp capacity.
•
Configurable auxiliary output. See “Auxiliary Output Functions” on page 1–8.
•
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 backfeed (reverse current) protection. Warning and Fault
messages appear on the LCD when the unit shuts down as a protective
measure.
•
Over-temperature protection and power derating when output power and
ambient temperature are high.
