Introduction
1–2 975-0560-01-01 Revision B
Features
This photovoltaic charge controller tracks the maximum power point of a PV array
to deliver the maximum available current for optimum charging of batteries. The
charge controller can be used with 24 and 48 VDC battery systems only.
The charge controller is designed to regulate the available power from a PV
source only. It is not designed to regulate power from other types of power
sources.
The charge controller can be installed (in single or multi-unit configurations) with
a Xantrex XW Hybrid Inverter/Charger or as a stand alone battery charger.
However, it is recommended that—at minimum—an SCP or Xantrex Gateway be
included in the system (see “Accessories” on page A–6 for product part
numbers). The System Control Panel (SCP) provides both status information and
the ability to change settings, while the Gateway (access via a personal
computer) provides status information only. An SCP is required for installation of
the charge controller.
Standard features of the charge controller include:
• Two- or three-stage charging process, with manual equalization to maximize
system performance and maintain expected battery life.
• 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).
• Fan-cooled with speed control based on internal (heat sink) temperature.
• 80 amp charging current capability.
• Configurable auxiliary output. See “Auxiliary Output Functions” on page 1–9.
• Three LEDs for displaying operating status (On/Charging, Equalize, and
Error/Warning).
• Input over-voltage protection, output over-voltage protection, output
under-voltage protection, and output over-current protection. Warnings,
errors, and faults are indicated by the red LED. View the associated warning
or error message on the SCP.
• Xantrex Xanbus™-enabled. Xanbus is a network communications protocol
developed by the manufacturer. The charge controller is able to
communicate its settings and activity to other Xanbus-enabled devices, such
as the Xantrex XW Hybrid Inverter/Charger, the SCP, the Xantrex XW
Automated Generator Start, and other charge controllers.
• Over-temperature protection and power derating of output power when
ambient temperature is high.
• Battery Temperature Sensor (BTS) to provide automatic temperature-
compensated voltage setpoints for battery charging. If the BTS is lost or
damaged, you can order a replacement from the manufacturer (part number
808-0232-02).
