  • Page 14: Features

    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. Figure 1-1 XW Solar Charge Controller Standard features of the XW Solar Charge Controller include: •...

  • Page 15: Maximum Power Point Tracking

    Xanbus -enabled. Xanbus is a network communications protocol developed by Xantrex. The XW SCC is able to communicate its settings and activity to other Xanbus-enabled devices, such as the XW Series Inverter/Charger, the XW System Control Panel (SCP), XW Automatic Generator Start (XW- AGS), and other XW Solar Charge Controllers.

  • Page 16: Charge Controlling

    Introduction Charge Controlling The XW SCC can regulate PV array current at 12, 24, 36, 48 or 60 volts DC for charging batteries. It produces up to 3500 watts and 60 amps of charging current for all battery voltages except 60 volts. Figure 1-3 PV Charge Controller The XW SCC controls how the batteries are charged by the DC source (the PV array).

  • Page 17: Absorption Stage

    Charge Controlling Absorption Stage During the absorption stage, the XW SCC continues to deliver its maximum available current output until the battery voltage reaches the absorption voltage setting. The XW SCC then operates in constant voltage mode, holding the battery voltage at the absorption voltage setting for a pre-set time limit (the default time limit is three hours).

  • Page 18: Two-Stage Battery Charging

    Introduction Two-Stage Battery Charging The two-stage charging process includes the bulk and absorption stages, but uses a “No Float” stage instead of “Float.” The relationship between charging current and battery voltage during the two-stage charging process is shown in Figure 1-5. No Float Stage During the No Float stage the XW SCC does not produce any charge current.

  • Page 19: Battery Temperature Compensation

    Charge Controlling Battery Temperature Compensation The Battery Temperature Sensor (BTS) automatically adjusts the charging process of the XW SCC. With the BTS installed, the XW SCC increases or decreases the battery charging voltage depending on the temperature of the battery to optimize the charge to the battery and to protect it from over-charge or damage.

  • Page 20: Auxiliary Output Functions

    Introduction Auxiliary Output Functions The XW SCC has a configurable auxiliary output (producing 5 to 13 volts and up to 200 milliamps) to drive a relay for load control or to turn on devices such as vent fans or indicator alarms. The auxiliary output can be configured to perform only one function at a time.

  • Page 21: Installation

    Installation Chapter 2 contains information and procedures to install the XW Solar Charge Controller. Before installing the XW SCC, read this entire chapter. Depending on your installation, you may need to perform certain installation stages in a different order than the order presented in this chapter.

  • Page 22: Pv Array Requirements

    Installation PV Array Requirements Note: The following information provides only general guidelines. The installation and rated performance of your PV array is subject to inspection and approval by the authority having jurisdiction. Each XW Solar Charge Controller (XW SCC) must be connected to its own PV array.

  • Page 23: Mounting

    Installation procedures will vary according to your specific application. For special applications, consult a qualified electrician or your Xantrex Certified Dealer. If installing the XW SCC as part of an XW System, see the XW Power System Installation Guide for additional information.

  • Page 28: Internal Ground Fault Protection

    Installation Internal Ground Fault Protection The XW SCC has a PV ground fault protection (PV-GFP) fuse (600 V, 1 A) and a PV negative-ground jumper located inside the wiring compartment. These provide a negative ground bond and ground-fault protection for negative grounded PV array systems common in North American installations.

  • Page 29: Disabling Ground Fault Protection For Negative Grounded And Ungrounded Arrays

    Grounding Disabling Ground Fault Protection for Negative Grounded and Ungrounded Arrays To install the XW SCC in a system where an external negative-ground bond is required or where the PV array must not be grounded, the XW SCC internal PV- GFP circuit and ground bond must be disabled.

  • Page 30: Wiring

    Installation Wiring Important: Installations must meet all local electrical codes.This equipment should only be installed by a qualified electrician or a Certified Renewable Energy System Installer. WARNING: Shock hazard Disconnect PV and battery circuits before wiring. DC Terminal Connector Locations Terminal connectors for DC wiring are located inside the wiring compartment.

  • Page 31: Minimum Wire Gauge

    Wiring Minimum Wire Gauge For installations where the PV array output is the maximum allowable 60 A I the minimum allowable wire gauge is #6 AWG (16 mm ) copper wire with a 90 °C (194 °F) insulation rating. This wire gauge is determined by electrical code requirements regarding conduit knockout sizes, wire bending radius, and space available within the XW SCC wiring compartment.

  • Page 32: Maximum One-Way Distance And Wire Size

    Installation Maximum One-way Distance and Wire Size Important: Local and national electrical codes must be followed for determining additional installation requirements. Refer to Table 2-3 and find the maximum current in the left column, and the one- way distance from the PV array to the XW SCC (or the distance from the XW SCC to the battery) on the same line, then read the wire size required at the top of the column.

  • Page 33: Connecting The Xw Scc

    Wiring Connecting the XW SCC The following procedure is illustrated in Figure 2-9.

  • Page 35: Connecting Multiple Units

    Connecting Multiple Units Connecting Multiple Units In a multiple-unit installation, each XW SCC must be connected to a separate PV array. For other multiple-unit installation considerations, see “Network Installation” on page 2–18. Important: Only one Charge Controller is to have the PV-GFP fuse installed in installations with multiple parallel XW SCCs.

  • Page 36: Aux Output Connections

    Installation Aux Output Connections WARNING: Shock hazard If the PV-GFP internal protection has activated, shock-hazardous voltage may appear at the AUX connector and at the battery terminals. To avoid a shock hazard, ensure that all connections made to the AUX terminals have no uninsulated wire segments and that all wiring has an insulation rating of at least 300 V.

  • Page 37: Disconnecting The Charge Controller

    Disconnecting the Charge Controller Disconnecting the Charge Controller WARNING: Shock hazard Ensure both the PV array and the batteries are disconnected from the XW SCC before servicing the XW SCC or the batteries. After disconnecting the batteries, the XW SCC can appear de-energized when the PV array is still connected.

  • Page 38: Network Installation

    XW Hybrid Inverter/Charger provides the required 15 Vdc/200 mA network power. • Network cables—Each Xanbus-enabled device is connected by a standard Ethernet (CAT 5 or CAT 5e) cable, available from Xantrex or any computer supply store. CAUTION: Equipment damage Do not use crossover cable.

  • Page 39: Ordering Network Components

    Table 2-4 provides a partial list of network components and part numbers. Cables are available in standard lengths from 3 feet (0.9 m) to 75 feet (22 m). Call your dealer or visit the Outlet Store at www.xantrex.com to purchase cables and other network components.
