Charge Controller Troubleshooting

975-0540-01-01 Revision B 3–3

This guide is for use by qualified personnel only.

The charge

controller’s Error/

Warning (red) LED is

on or flashing.

An active fault, error, or warning is

present on the charge controller.

See “Viewing Active Faults, Errors,

and Warnings” in the Xantrex XW

MPPT 80 600 Solar Charge Controller

Operation Guide to determine which

alarm is active on the charge

controller. The tables in this section

provide detailed information on why

various alarms could be occuring on

the charge controller.

The charge

controller’s Error/

Warning (red) LED is

on, and the SCP

indicates a ground

fault (F56) for the

charge controller.

A ground fault has caused the ground

fault protection fuse to blow, or a

normally ungrounded array contains a

ground fault.

See “Replacing the Ground Fault

Protection Fuse” on page 3–4 or

“Ground Faults in a Normally

Ungrounded Array” on page 3–5.

The charge

controller’s Error/

Warning (red) LED is

on, and the SCP

indicates an output

under voltage error

(F11) for the charge

controller.

A. The default configuration for the

charge controller is a 48 V battery

bank, and you have installed the

charge controller on a 24 V battery

bank.

B. The batteries are dead or

undercharged.

A. Use the SCP to configure the

charge controller for 24 V operation.

See “Configuring Battery

Characteristics and Battery Charging”

in the Xantrex XW MPPT 80 600 Solar

Charge Controller Operation Guide for

more information.

B. Check the battery voltage to see if

the batteries are within operating

specifications. If necessary, replace

them with new batteries, or use a

device capable of performing dead

battery charging.

The charge controller

does not show up on

the SCP or it drops off

the network

periodically.

A. Network terminators have not been

installed at both ends of the Xanbus

network.

B. The total network length exceeds

the maximum length specification.

A. Install a terminator at each far end

of the network. See “Network

Components” on page 2–17 for more

information.

B. See “Network Layout” on

page 2–18 for specifications.

The charge controller

does not produce any

power.

A. No PV input voltage.

B. PV input voltage is not within

operating range.

A. Change the PV disconnect switch

from the off position to the on position.

B. Make sure that the PV panels are

configured to provide voltages within

the charge controller’s operating

voltage window.
