Replacing the Ground Fault Protection Fuse

The ground fault protection fuse blows when a significant leakage current flows

between the PV array and earth ground or when the system has been installed

with deficient wiring. Before replacing the fuse, it is important to have qualified

service personnel, such as a certified electrician or technician, determine the

cause of the ground fault and effect repair.

To replace the ground fault protection fuse:

1. Make sure the PV and battery disconnect switches are open and the charge

controller is de-energized.

2. Remove the wiring compartment cover, as described on page 2–5.

The ground fault protection fuse is located behind the wiring terminals.

All of the charge

controller’s LEDs are

off and the charge

controller does not

show up on the SCP.

A. No battery connection to the charge

controller.

B. The charge controller is miswired.

C. Failed charge controller.

A. Change the battery disconnect from

the off position to the on position.

B. Check all connections and correct

the wiring if voltage is not present on

the charge controller’s battery

terminals.

C. If you have verified there is at least

20 V present on the charge controller’s

battery terminals yet the On/Charging

(green) LED remains off, contact

customer service.

The charge

controller’s On/

Charging (green) LED

is flashing.

The charge controller is outputting

charge current.

No problem. This is intended

operation. See “Viewing Status

Information on the Xantrex XW MPPT

80 600” in the Xantrex XW MPPT 80

600 Solar Charge Controller Operation

Guide for LED status information.

DANGER

HAZARD OF ELECTRIC SHOCK

If a ground fault is indicated, normally grounded PV conductors could be

ungrounded and energized. Before working on any portion of the array or

wiring, make sure that portion of the array is de-energized by blanketing, use

of disconnects, or other safe working procedures and by testing for voltage

before beginning work.

Failure to follow these instructions will result in death or serious injury.
