Schneider Electric XW-MPPT100-600 Charge Controller

Schneider Electric XW-MPPT100-600 Charge Controller, 100A, 600V, 24 or 48VDC, UL/CSA, 865-1034, RNW8651034

Optimum system performance and flexibility with DC coupled solar with storage

The Schneider Electric Solar Charge Controller (SCC) is a photovoltaic (PV) charge controller that tracks the electrical maximum power point of a PV array to deliver the maximum available current for charging batteries. When charging, the SCC regulates battery voltage and output current based on the amount of energy available from the PV array and state-of-charge of the battery. Schneider Electric's latest Conext MPPT 100 amp, 600 volt DC charge controller is the most efficient voltage controller on the market. Wire size and distance from the charge controller are important design elements when dealing with very high-power solar arrays. The maximum DC input voltage of 600 volts allows for higher string voltage and overall device operation. When your solar array must be mounted far away from the charge controller, this model is ideal because you can use a smaller wire size to deliver power to the controller if you simply customize your array for a higher voltage. When you consider the cost savings that comes when using a smaller wire scale, this controller can help save money on your installation costs. This controller can also be used to charge batteries from grid-tie arrays with high voltage.

The Schneider Electric XW-MPPT100-600 Charge Controller provides optimal device output for DC-coupled solar and storage installations, as well as simple and versatile PV array installation. The MPPT 100 is suitable for residential grid-tied self-supply and off-grid networks, and is flexible for larger installations, with up to 6 kW of charging capacity and allowance for over-sized arrays. With 2 string installations, the XW-MPPT100-600 provides faster installation and a lower balance of device costs, plus it is also compatible with Conext XW and SW inverters. The MPPT PV array input window is 195 to 550 VDC, which supports an output of up to 100 amps for 24 or 48 VDC battery banks. The charge controller has a configurable single-function auxiliary output to drive a load control relay or to activate devices such as vent fans or indicator alarms. Full output current of 100A is available without de-rating in ambient temperatures up to 113 °F (45 ºC). Over-temperature protection de-rates the power throughput when ambient temperatures are higher. The XW-MPPT100-600 also features protections for input over/under voltage, output over current, and back-feed (reverse current). Built-in ground-fault protection (GFP) eliminates the need for a separate GFP breaker. This unit is configurable for positive, negative, and ungrounded PV systems. Standby power draw is less than 1 W. For NEC 2017 compliance with module-level rapid shutdown and equipment disconnect features, the MPPT Disconnect RS accessory can be installed.

The XW-MPPT100-600 can be used with the XW Power Distribution Panel, or stand-alone in other PV systems. You can use a Square D HU361RB 600 VDC Disconnect, or the XW-Disco-RS as an array disconnect. Use a 125 A breaker for the XW-MPPT100-600 on the battery side of the controller.

A battery temperature sensor is included with the controller. The XW-MPPT100-600 is compatible with Xanbus-enabled devices, such as the XW Series inverter/charger, the System Control Panel, Conext Gateway, XW Automatic Generator Start Module, and other XW solar charge controllers through the Xanbus network. It can also be installed in a stand-alone mode with an XW System Control Panel or Conext Gateway.

NOTE: The SCP (sold separately) provides a wall mount display for monitoring and fault reporting and is needed for setup and configuration
