The XW-MPPT80-600 and XW-MPPT100-600 controllers can accommodate open circuit voltages of up to 600 VDC, which reduces wiring needs, increases module selection and string sizing flexibility, and enables greater distance between the power source and battery bank. The MPPT PV array input window is 195 to 550 VDC, which supports an output of up to 80 A or 100 A for 24 or 48 VDC battery banks. Standby power draw is less than 1 W.
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 80 A or 100 A 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. They also feature 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.
The XW-MPPT80-600 or XW-MPPT100-600 can be used with the XW power distribution panel, or stand-alone in other PV systems. Either a Square-D HU361RB 600 VDC disconnect, or the XW-Disco-RS, can be used as an array disconnect. Use a 100 A breaker for the XW-MPPT80-600 and 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-MPPT80-600 and XW-MPPT100-600 are 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.
XW-MPPT80-600 and XW-MPPT100-600 dimensions are 30"H x 8.63"W x 8.63"D, weight is 29.8 lbs. and it is covered by a 5-year warranty with an optional extension to 10 years. Listed to UL 1741 and CSA 107.1 for the U.S.A. and Canada.
