Manual Printed in China
Please note the installation shown is for connections to the Nature Power 8 Amp charge controller. To receive
information on connections with the 28 Amp Charge Controller please refer to the 28 Amp charge controller
manual.
When installing solar panels configuration and systems, please carefully observe correct cable connections and
polarity. The solar panels can be damaged by not observing the correct electrical installation and polarity; in
addition, this will void the warranty of your solar panel(s). Having a multi-meter handy will help to confirm
correct polarities.
Extending the wiring
If you choose to mount your solar panel further away from the charge controller by extending the wiring we
recommend the following gauges at each specified distance. Use stranded wire instead of solid wire. Stranded
wire does not fatigue or loose connections over time.
Cable Length American Wire Gauge (size)
20-30 Feet #12
40-50 Feet #10
60 Feet or more #8
To prevent loss of current we suggest mounting the solar panel within 20 feet of the charge controller and the
charge controller should be installed within 5 feet of the battery.
Additional Solar Panels
You may choose to purchase additional solar panels for higher wattage and faster charging. Connecting more
panels is easy with the EZ connector cables.
Figure 2 shows an example of how to connect more panels together with the EZ connector cables. If needed EZ
3-in-1 or EZ 4-in-1 connector cables are available and can be purchased from Nature Power please contact our
Customer Service line to get more information on purchasing EZ connector cables.
Additional 12V DC Batteries
Addition batteries may be desired for extra electrical storage.
For 12 Volt battery bank configurations; make sure your batteries are connected in parallel (Positive to Positive
and Negative to Negative)
1. From the charge controller attach the red battery clamp to the red terminal of the first battery in the
bank, matching the polarities, positive to positive.
