- Page 2 WARNING • For installations with lead acid batteries, avoid sparks or flames near the batteries and always use proper eye protection. • Given sufficient light, solar panels always generate energy even when they are disconnected. Accidental ‘shorting’ of the terminals or wiring can result in sparks causing personal injury or a fire hazard. It is recommended that the front face of the panel(s) are covered with a soft cloth to block incoming light during installation and wiring.

Page 4: Installation
INSTALLATION PLACEMENT Locate the panel in a position where it is exposed to the sun for the majority of the day. For best results use a northern orientation. Make sure that the front side (dark side) of the solar panel faces the sun. Although the panel will function in the horizontal position, for best performance tilt the panel towards the sun especially during the winter months in the southern states. - Page 5 MOUNTING The panels are supplied with four or eight mounting holes (depending on the model). Use suitable fasteners and mount the panel to a flat surface or mounting frame as per fig. 1, 2 & 3. Ensure the battens or frame does not twist or bend the solar panel’s aluminium frame.

Page 8: Charge Control
CHARGE CONTROL Solar panels are most commonly used to charge lead acid batteries. Projecta solar panels are designed to charge 12 VDC batteries. 24VDC batteries can be charged using 2 panels wired in series and using a 24VDC solar charge controller. - Page 9 CONNECTING SOLAR PANEL TO BATTERY Projecta products are covered by a 12 month warranty. Failure to follow the operating instructions may damage the product and will void warranty. Please read these operating instructions carefully before use. For a warranty claim please return unit to the place of purchase with your sales receipt as proof of purchase date.

Page 17: Maintenance
MAINTENANCE Periodically inspect the electrical connections and panel mounting bolts. Make sure they are all tight and free from corrosion. If necessary clean the surface of the solar panels with a soft dump cloth. Mild detergent can also be used. Any dirt or residue on the glass may effect performance. FREQUENTLY ASKED QUESTIONS Q. - Page 18 Q. Will the solar panel charge my flat battery & how long will it take? A. 1. The SPM25 is designed for ‘topping up’ and maintaining batteries. Given sufficient time it will put some charge back into the battery. 2. The SPM50, SPM80, SPM95, SPM155-MC4, SPM170-MC4, SPM200-MC4 will charge a battery.
