4. Automatic Equalization - This feature is activated once per day to
extend the life of your batteries by allowing the weaker cells a chance to
catch up with the stronger cells. This assures that all cells will be at an
equal state of charge. The first time domestic batteries reach 14.2 Volts
during the day, a delay timer is activated that allows a short duration
period (20 to 30 minutes) at a slightly higher voltage (14.5 to 14.7 Volts)
and then falls back to the 14.2 Volt setting for the remainder of the day.
A critical part of maintaining the solar electric battery charging system is to
keep the panels clean. The amount of power which a panel will produce is
directly related to the intensity of sunlight which reaches it. A dirty panel will
allow less light to reach the panel resulting in less power produced. A single
layer of dust or road grime can reduce the power output by 15 to 25%. Leaves
and debris which can cover two or three of the 36 individual cells can reduce
output power by 50 to 75%.
Use of the basic maintenance tips, regular inspections and regular cleaning
will assure you of maximum charging from your solar electric system. A non-
abrasive cleaner and paper towels are recommended. The surrounding environ-
ment and the amount of road dust encountered determines how frequently the
panels should be cleaned. One to two times a month is preferred.
Tips to follow
1. If you can see a film or a layer of dust on the windshield chances
are your panels should be cleaned.
2. On a bright sunny day the charging amps should be 3.5 to 5 amp for
each panel.
3. High winds blow dust and debris around causing dirt build up.
Frequently inspect the panels and clean as necessary.
CAUTION: Avoid damage to the solar panel controller.
Cover the solar panel with a blanket when externally charg-
ing the batteries or performing battery cable maintenance.
