Inverter/Charger Installation

Making AC Connections

This section describes how to make AC connections between the XW Inverter/Charger and the XW Power Distribution Panel (using the pre-installed AC wiring in the XW Power Distribution Panel) and between the XW Power Distribution Panel and the AC distribution panel, or sub-panel (using wiring provided by the installer). See Appendix C, “Alternate System Configurations” if the installation will not be including an XW Power Distribution Panel.

CAUTION: Damage to the Inverter

The inverter’s AC output must never be wired to the utility or generator output. This will cause severe damage to the inverter which is not covered under warranty.

Do not use a GFCI equipped AC source to power either the grid or generator inputs. The AC input filters on the XW may cause nuisance tripping of ground fault protected outputs.

AC Connections and Communication Ports

AC Connections	The AC terminal block includes three terminals each (L1, L2 and Neutral) for AC Grid
	input, AC Generator input, and AC Load connections. The neutrals are connected to each
	other, requiring only one neutral connection when installed with an XW Power
	Distribution Panel. Without the XW Power Distribution Panel, additional neutral
	connections may be required at the input sources.
Communication	Four communications ports and one AUX Port are located on the bottom of the inverter
Ports	and support the following features.
	• The two AC sync ports are used for connecting multiple inverters in parallel.
	• The two Xanbus ports are used for network connections between inverters, charge
	controllers, and accessories.
	• The AUX port provides 12 Vdc/250 mA output to control a relay, fan, indicator light
	or other device. The auxiliary output can be configured (using a XW System Control
	Panel) to trigger in response to low- or high-battery voltage or high- or low-battery
	temperature. The auxiliary output can also be triggered manually using a XW System
	Control Panel.
