Wiring

Important: Installations must meet all local electrical codes. Installations of this equipment should only be performed by a qualified electrician or a Certified Renewable Energy (RE) System Installer.

WARNING: Shock Hazard

Disconnect battery and PV sources before wiring.

DC Terminal Connector Locations

Terminal connectors for DC wiring are located inside the wiring compartment. The labels above the DC wiring terminals and inside the wiring compartment identify all the connection points. See Figure 4-7.

Wire Size and Over-current Protection Requirements

	The wiring, over-current protection devices (fuses and circuit breakers), and installation
	methods used must conform to all national and local electrical code requirements.
	Wiring must be protected from physical damage with conduit or a strain relief clamp.
	The BTS, auxiliary output, and network cables must pass through a different conduit than
	the conduits used for PV wiring and battery cables. Pull the BTS cable through the conduit
	first as the connector may not fit if other wires have been pulled first.
Current rating	The XW Solar Charge Controller is rated for 60 A maximum Isc. Since PV outputs can
	vary due to the array size or sunlight striking it, the safe minimum wire size must be
	chosen for maximum array short-circuit current. Consult PV array manufacturer
	specifications.
Minimum wire	For installations where the PV array output is the maximum allowable 60 A Isc, the
gauge	minimum allowable wire gauge is #6 AWG (13.3 mm2) 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 Solar
	Charge Controller wiring compartment.
	No crimp-on terminals or lugs are required.
Over-current	Over-current protection must be installed for the battery and PV circuits to protect the XW
protection	Solar Charge Controller from short circuits at its input and output. The NEC requires all
	circuits to be protected with a device rated for 125% of the rating of the circuit.
