XW Solar Charge Controller Installation

Connecting the XW Solar Charge Controller to the Distribution Panel

WARNING: Shock Hazard

Whenever a PV array is exposed to light, a shock hazard exists at the output wires or exposed terminals. To reduce the risk of shock during installation, cover the array with an opaque (dark) material before making the connections. PV arrays generate voltage whenever light strikes the surface of the array. Before connecting the XW Solar Charge Controller, cover the array to prevent any current from being generated.

WARNING: Shock Hazard

Do not connect the battery negative to ground. Bonding the battery negative to ground disables PV ground-fault protection.

To connect the XW Solar Charge Controller:

1.Connect the PV array’s positive (+) output to the PV array disconnect.

2.Route another (+) cable from the other end of the PV disconnect to the terminal marked PV + in the XW Solar Charge Controller.

3.Connect the PV array’s negative (–) output to the terminal marked PV – in the XW Solar Charge Controller.

4.Connect a positive (+) cable from the terminal marked BAT + to the battery disconnect.

5.Connect a second positive (+) cable to the other side of the battery disconnect and connect to the positive (+) battery terminal.

6.Connect the negative (–) battery cable to the terminal marked BAT – in the XW Solar Charge Controller.

7.Torque the Charge Controller terminals as follows.

•15 inch-pounds (1.7 Nm) for #14–10 AWG wire

•18 inch-pounds (2.0 Nm) for #8 AWG wire

•20 inch-pounds (2.2 Nm) for #6 AWG wire.

Be careful not to overtighten. Allow some slack on the cables within the controller and secure the wiring with strain reliefs or cable clamps.

See Figure 4-8.
