Item 68738
If the overload discharge is triggered in this mode,
the load output will be cut off. Pressing the Load
Switch will cause an alarm to sound.
Once system recovers from over discharge or
overload, press the Load Switch to reset the load
output function.
3. Press the Display Button a third time and the LED
will show the charging current from the solar panel
to the battery (18A).
Pressing the Switch Button in this mode will change
the LED display.
WARNING!
Connect Battery Clamps according
to correct polarity (red for positive and black for
negative.) Do not short circuit the Battery Clamp.
NOTICE:
When installing Charge Controller to
Solar System, always verify that battery voltage and
solar panel voltage are matching. The input current
from the Solar Panel should not exceed the max.
solar input current limit of the Charge Controller.
NOTE:
It is normal for the current on LED display
to change. Since the battery is changing between
charging and discharging status when in over-
charger protection, the current variation is normal.
Overcharge Protection
When the battery voltage is too high, the Controller
will stop charging to avoid overcharging. When battery
voltage decreases, the Controller will start charging again.
Discharge Protection
When battery voltage drops too low, the Controller will
cut off the power to the load to prevent battery damage.
Servicing
Procedures not specifically explained in this
manual must be performed by
a qualified technician.
TO PREVENT SERIOUS INJURY
FROM ELECTRIC SHOCK:
Before service, maintenance or cleaning:
a.
Dry Charge Controller and outdoor
wiring thoroughly while wearing
electrically insulated gloves.
b.
Cover solar panel with an opaque
cover, such as a blanket.
c.
Disconnect solar panel after use.
d.
Disconnect all batteries after use.
TO PREVENT SERIOUS INJURY FROM
ELECTRIC SHOCK OR CUTS:
Do not use damaged Charge Controller.
If wiring insulation is damaged or
weathered, solar panel glass is cracked,
or housing is opened, have the problem corrected
before further use.
Note:
It is normal to see up to 20% degradation in
amorphous silicon solar panel performance within the first
6 months before the amorphous coating stabilizes.
Cleaning
Clean and inspect all parts of the Solar
Power System
MONTHLY
, or more
frequently to maintain peak efficiency.
1.
Wear electrically insulated gloves and
ANSI-approved safety goggles.
Dry solar
panel and outdoor wiring thoroughly.
2.
Cover solar panels with an opaque
cover, such as a blanket.
3.
Disconnect solar panel and batteries.
4. Clean solar panel with mild, non-abrasive
cleanser and soft cloth and paper towels. Do
not clean with brushes or abrasive cleaners.
5. Inspect the general condition of the Solar Power
System, including panel, batteries, controllers,
and mounting connections. Check for loose
hardware, wiring insulation damage or weathering,
cracked glass, open housing, cracked or broken
parts, loose or corroded contacts, and any other
condition that may affect its safe operation.
6. Inspect and maintain batteries according
to supplier’s instructions.
Adjustment
To increase efficiency:
1.
In the Winter,
increase the panel’s angle by 10°.
2.
In the Summer,
decrease the angle by up to 10°.
3.
In the Spring and Fall,
keep the panel at the angle
recommended by solar panel’s instruction manual.
