GENERAL SAFETY
Precautions when working with Charge Controller Model no. SCC-30AB
If two or more solar panels are connected in series/parallel make sure that the sum of the short circuit current
ratings of all panel strings does not exceed 80% of the charge controller’s current rating i.e. 24 Amps for the
30 Amp charge controller. The open circuit voltage of the solar array i.e. the maximum voltage across the array
should not exceed 26 V when the 12 V setting on the charge controller is used and not exceed 52 V when the
24 V setting on the charge controller is used.
3.2. Routine Maintenance
•
Inspect the solar panels and make sure the surface is free from dust, dirt and other debris,
clean with a wet cloth or glass cleaner, if necessary.
•
Check to make sure all structural components, mechanical fasteners and electrical connections are
secure, clean and corrosion-free.
•
Check and maintain the battery electrolyte levels at regular intervals as per the battery manufacturer’s
recommendations if flooded wet cell lead acid batteries are used.
•
Check and replace damaged components if necessary.
3.3. Installation Overview
1. Read the manual in detail and understand the installation procedure.
2. Open the packaging and check to make sure that all parts have been received as per the parts list
in the manual.
3. Arrange for the required tools to carry out the installation. A sample list of tools (not exhaustive)
is provided in Section 4.
4. Determine the mounting location of the solar panel(s) on the roof of the RV.
5. Mount the charge controller at the desired location (see Section 5).
6. Pass the cable from the solar panels to the interior of the RV (See section 6).
7. Wire the battery to the charge controller and then the solar panel to the charge controller ensuring
the correct polarity is observed (See Section 6).
8. Secure the solar panel to the RV roof (See Section 7).
