Maintenance
NOTE: These panels will produce electricity on a continual basis depending on
the amount of sunlight they receive, as long as they have a completed circuit
and the temperature control is adjusted to the ambient temperature.
1. Be aware that the exhaust fan may operate automatically whenever a solar
panel is exposed to sunlight or there is charge in the battery.
2. Some batteries will be damaged if they are continuously charged. Do not
leave the fan disconnected and any battery attached to this system. Although
the control unit has a built-in regulator, it may not protect the battery in all
situations.
3. Keep the solar panels clean. Wipe them occasionally using a damp cloth
with mild detergent. Do not use abrasives. Dirt on the glass will reduce the
capacity of the panels to receive sunlight.
4. Periodically check the wiring, mounting and status of the system. Repair any
unsafe condition immediately.
5. If the unit stops working even in bright sunlight, check the fuse. Open
the fuse container on the side of the Control Unit by turning the fuse cap
counterclockwise. If the fuse wire is broken, replace the fuse with an identical
3 amp fuse. Replace and tighten the fuse cap.
Electrical Power Sources Connected in Series and Parallel.
Solar Panels, batteries and other power sources may be connected in a circuit in
“Series” or in “Parallel”. When connected in series, the voltage is combined while
the Amperage is unchanged. When connected in parallel, the voltage remains
unchanged while the amperage is combined.
In series, the voltage is combined while the amperage is unchanged.
In parallel, the voltage remains unchanged while the amperage is combined.
