Nature Power Products 

 

Nature Power Monocrystalline Solar Cells are manufactured in Germany by Bosch and Solar Panels are assembled in China. 

Manual Printed in China 

Precautions when working with Charge Controllers 

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. 8 Amps or 28 Amps.

Installation Overview 

 

Open the packaging and check to make sure that all parts have been received.  

 

Arrange to have on hand the proper tools to carry out the mounting installation. 

 

Determine the mounting location of the solar panel(s). 

 

Mount the charge controller within 5 feet of battery or loss of current may occur. 

 

Wire the battery to the charge controller and then the solar panel to the charge controller to ensure that 

the correct polarity is observed. 

 

Secure the solar panel to the desired location, solar panel must be within 20 feet of the battery, or loss of 

current may occur. 

Selecting the correct Charge Controller 

Charge Controllers may be sold separately and are required for installations of solar systems arrays that are 

rated 12 Watts and higher. Charge Controllers help to protect the battery(s) and solar panel(s) from harmful 

reverse currents, battery over charging and high wattage surges, addition protections are found on larger 

charge controllers. Nature Power Products offers an 8 Amp Easy-to-Connect Charge Controller (60008) and a 28 

Amp Digital PWM Charge Controller (60028). You may also choose to use a non-Nature Power charge 

controller, however, please confirm that it is a 12 Volt DC charge controller. Also installations for non-Nature 

Power charge controllers may not be compatible with the EZ connect cables from the monocrystalline solar 

panel.
