Before working on a PV array, disconnect the PV array from the solar regulator and the batteries by
placing the Breaker/Switch to the OFF position.
To optimize PV panel performance, keep the panels free of dirt, dust, snow, or any other contaminants that
prevents the sun from directly striking the panel. Avoid placing panels in areas where they are shaded at
any time. Remove dust and other items with soft cloth or sponge and water. A mild non-abrasive detergent
may be used on persistent contaminants. In areas where snowfall is possible, it is necessary to remove it as
the need arises.
Batteries
Note
& &
You can skip this maintenance requirement if your application
does not have batteries.
Caution
Warning Charging batteries produce hydrogen, which can explode when
proper operating procedures are not followed. To prevent
severe personal injury, death, or substantial property damage
when working around batteries, be extremely careful. Always
use approved eye protection, face shield, rubber gloves, and
insulated tools.
Electrolyte Levels
Bi-weekly:
It is important to maintain the proper level of electrolyte in the batteries
at all times. If the level is too high the electrolyte will “boil” out of the
top of the battery during charging and corrode the terminal connections.
If the level is too low the battery life will be severely shortened.
Electrolyte levels should be just below the bottom of the vent well, about ½ to ¾ inch above the tops of the
separators. The electrolyte level should not drop below the top of the plates. See figure 1 for additional infor-
mation.
