6. Inspect for dirt, insects, nests, and corrosion.

7. Check that the controller functions and LED indicators are

correct for the system conditions at that time.

ROUBLESHOOTING

If something seems wrong with the PV system (for example,

the load is not working or the battery is not charging), then

it may be necessary to troubleshoot the controller. Some

basic troubleshooting procedures are listed below.

CAUTIONS:

• Troubleshooting should be attempted by qualified

personnel only.

• Remember that a battery can cause serious damage if

shorted.

• Do not disassemble the ProStar from its case. There are

no user serviceable parts inside the ProStar.

• Observe all normal precautions when working with

energized circuitry.

NOTE: There are no internal fuses or circuit-breakers in the

ProStar case. There is nothing inside the case that

can be adjusted, and there are no consummable

parts to replace.

HARGING

a. Check for proper LED indications on the ProStar. The green

CHARGING

LED should be on if it is daytime. One of the

BATTERY CHARGE

LED’s should be on. If the ProStar

includes the meter option, check for proper battery voltage

and array current.

b. Check that the proper

BATTERY TYPE

has been selected.

c. Check that all wire connections in the system are correct and

tight.

d. Measure the PV array output voltage and confirm it is within

normal limits. If the voltage is low or zero, check the connec-

tions at the PV array itself. Disconnect the PV from the con-

troller when working on the PV array.

e. Check that the load is not too large.

f. If the

BATTERY SENSE

terminals are not being used, there

may be excessive voltage drops between the controller and
