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.

Key product features include a 600 VDC maximum input voltage, a Fast Sweep™

MPPT tracking algorithm, and built-in ground fault protection. For information on

additional product features, see the Xantrex XW MPPT 80 600 Solar Charge

Controller Operation Guide (Document Part Number 975-0560-01-01).

The high input voltage operating range allows a high-voltage and low-current PV

array to be connected to the charge controller. A one- or two-string, high-voltage

PV array configuration can eliminate the need for a combiner box and associated

DC circuit breakers as well as use small AWG wire for array wiring. This simplified

array configuration can reduce hardware costs as well as installation labor costs,

and it also allows for long home-run wiring with minimal power loss.

The Fast Sweep MPPT algorithm frequently conducts a very fast sweep of the full

operational array voltage window to dynamically determine the array’s maximum

power point. This feature helps deliver consistently high energy harvest for the

system, including when the array is partially shaded.

You can configure the built-in ground fault protection for a negative, positive, or

ungrounded PV array. The charge controller is compatible with all PV module

manufacturers. The charge controller regulates 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 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.
