Nature Power 8 Amp Charge Controller

  

is an easy to connect and easy to read charge controller with LED light indictors for battery 

charging 

cut-in voltage 13V

 and battery full 

cut out voltage 14.2V

. The 8 Amp Charge Controller 

is compatible with solar system arrays rated up to 130 Watts.  

 

Protections:

Nature Power 28 Amp Digital PWM Charge Controller

  

With Pulse Width Modulation (PWM) technology this charge controller helps to maintain a 

higher charging efficiency, thus maintaining a higher battery reserve and capacity than the 

standard on-off 8 Amp charge controller. The 28 Amp Digital PWM Charge Controller 

features a digital LCD display and adjustable voltage settings. 

Protections:

Selecting the correct Battery 

Nature Power does offer batteries. However, please choose a 12 Volt rechargeable battery. Do not attempt to 

recharge non-rechargeable batteries. 6 Volt battery configurations may also be used if connected in series 

(Negative to Positive).  You may choose a Sealed Lead Acid battery, a Gel-Cell or a Deep Cycle 12 Volt battery.  

Batteries come in all different sizes, Please converse with your battery dealer for more information on which 

type of battery you should use for your system. Note your solar panel amperage rating when selecting your 

battery size. 

 

Easy Electrical Installation 

Please confirm that you have all parts to your system before 

starting installation.  
Figure 1 shows how to connect the solar panel to the 12 Volt 

batteries 

Step 1 

Connect the charge controller to the solar panel 

Step 2 

Connect the battery clamps to the charge controller 

Step 3  

Connect the battery clamps to the battery in parallel. 

(Parallel connections = Positive to Positive and Negative to 

Negative)
