Page 3: General Safety
1.General safety *Do not disassemble the module or remove any attached nameplates and components from the module. *Please abide with all local, regional and national statutory regulations when installing the system or mounting on vehicles. Obtain a building permit when necessary. *Please cut off the electricity before carrying out the installation. -

3.Solar Panel Installation 3.1 Location Determine a location for the solar panel that is in direct sunlight and clear of any shading by adjacent obstacles such as trees, roof over- hangs, etc. Ideally, the panels will be positioned to minimize the wiring distance between the solar panel and the charge controller. - Page 5 Step2:Mark and drill holes Mark the holes for the well-nut. Step 3: Attaching the panel to the roof Figure picture below illustrates the correct way to use the well-nut. The rubber flange has to be flush with the roofline. The Z-Bracket,along with the flat washer and lock washer, hold the well-nut in place when the screw is fastened.

Page 6: Connection Method
Gently insert the well nut into the drill hole . Be careful not to push the well nut flange completely into the holes. Make sure the flange is flushed on the roofline.Before attaching the panel to the roof, a film of caulk can be laid between the RV roof and the Z-Bracket. - Page 7 2.Connect the battery to the controller. First, connect the negative cable to the negative (−) battery post. The best way to secure the battery cable to the battery post is by using a ring terminal. A bolt is sufficient to secure the ring terminal onto the battery post, allowing for better electrical contact.

5.Testing and Troubleshooting Testing Test all electrical and electronic components of your system before commissioning it. Follow the instructions in the guides supplied with the components and equipment. ·Test modules connected in series before they are connected to the system. ·To determine Voc and Isc in the following tests, the module(s) must be exposed to the sun and not connected to a load. - Page 12 ·Determine the short-circuit current (Isc) of every series circuit. It can be measured directly by connecting the digital multimeter to the two termi- nals of the series circuit or module. Attention, the rated scale of the ammeter or the rated current of load should be more than 1.25 times of the rated short-circuit current of the series module.
