Precautions when working with batteries

• Never smoke or allow a spark or flame near the batteries
• Batteries generate hydrogen and oxygen during charging resulting in evolution of explosive gas mixture. Care should be taken to ventilate the battery area and follow the battery manufacturer’s recommendations
• Batteries contain very corrosive diluted acid as electrolyte. Precautions should be taken to prevent contact with skin, eyes or clothing
• Use caution to reduce the risk of dropping a metal tool on the battery. It could spark or short circuit the battery or other electrical parts and could cause an explosion
• Remove metal items like rings, bracelets and watches when working with batteries. The batteries can produce a short circuit current high enough to weld a ring or the like to metal and thus cause a severe burn
• If you need to remove a battery, always remove the ground terminal from the battery first. Make sure that all the accessories are off so that you do not cause a spark
• Only use rechargeable 12 Volt batteries, ie. Sealed Lead Acid , Deep Cycle, Gel – Cell etc.
• Use properly insulated tools only when making battery connections
• When working with batteries please follow the battery’s manufacturer manual and precautions

Precautions when working with solar panels

With the incidence of sunlight or other light sources on all solar panels, a voltage appears at the output terminals of the solar panel turning it into a source of electricity. Do not make contact with the terminals when the panel is exposed to sunlight or other light sources. To avoid shock hazard make sure the solar panel is either turned over so the cells are not exposed to light or cover the cells with an opaque dark material such as paper/cloth during the installation process.

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.

Assembly Instructions

Selecting the Correct Battery

We do not offer batteries. However, please choose a 12 Volt rechargeable battery. Do not attempt to recharge non – rechargeable batteries. 6 Vol t battery configurations may also be used if connected in series Negative to Positive. You may choose e 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.

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

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 panels . 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.
Appropriate wire gauge should be used for distance and total amperage, for further information please consult with a licensed electrician or through an online wiring chart calculator.
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.

Mounting the Solar Panels

Recommendations Choose a site for mounting the solar panels that is free from shade and located in an area that receives maximum sunlight daily. For maximum solar power absorption through out the day, a tilt-mounting kit is recommended.
When making connections ensure polarity is maintained, reverse polarity may cause damage and will void the warranty.
Measure the distance between the mounting site and the battery location. The charge controller should be mounted in close proximity to the battery bank within 5 feet. Refer to the DC electrical wire guide to choose an appropriate gauge wire for the length of the wire.
If you choose to mount your Solar Panel to your RV, be sure you solidly mount your panels to the roof. If you have a rubber roof over thin plywood you may want to use molly fasteners to get a better grip. If you have a fiberglass roof, drill some pilot holes through the fiberglass to reach plywood below. This will prevent cracking or damaging the fiberglass. If your RV is equipped with a metal roof you must mount the solar panel to the joists supporting the roof.

The wire from the sola r panel can be routed to the interior r o f the RV through the roof – top refrigerator vent. In this kind of installation attempt to mount the panel near the refrigerator vent. See Figure 4.

Connecting Additional Solar Panels

Assembly:

1. To connect 2 Solar Panels together simply remove the connecting plugs at the end of each solar panel to reveal at least 2 inches of bare wiring.
2. Once the two wires are exposed they can be connected together by either twisting the wires together or by using solder. When connecting the wires always ensure the correct polarity is observed, Negative – Black to Negative and Positive + Red to positive.
3. Once the wires are connected they can be place in/on the correct terminals of your charge controller.
4. Once the wires have been placed on their terminals correctly ensure the connection is safe and secure and that the bare wires cannot come into contact with each other. This can be done by using insulation tape or electrical tape that can be wrapped around the wires to stop the coming into contact with one another.
   Note :
   If the Solar Panel wires short while being connected to the Charge Controller it may cause irreparable damage. Removing the connecting Plugs will not affect the warranty on Solar Panels.

Tools Needed:

• Crimping Tool/ Wire strippers
• Solder and Soldering Iron optional
• Electrical Tape

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.

2. Then connect the black alligator clamp to the black terminal of the second or late battery in the bank, again matching polarities, negative to negative. This will ensure an equal charging across both or all batteries.

Connect an Inverter

An inverter can be used to converting the 12 Volt energy created to 120 Volt Electricity. Inverter sizes and types vary depending on your power consumptions needs. Please discuss which inverter to purchase with your Inverter dealer.

Monitoring your solar system

To confirm that you r sola r panels are generating power w e suggest purchasing a multi meter . Annual testing and inspections are recommended to confirm all connections are secure and panels are functioning properly. Open voltage testing of solar panels may range from 11 Volts up to 21.6 Volts depending on the intensity of the sun, this is within normal range.
Upon annual inspections it is recommended to wipe all solar panels with a damp towel to remove dust and debris covering the panels, as layers of dust can affect the solar panel voltage.

Routine Maintenance Check List

• Check and replace damaged components if necessary
• Clean with a damp towel or cloth remove all debris
• Check and maintain the battery electrolyte levels are at regular intervals as per the battery manufacturer’s recommendations if flooded wet cell lead acid batteries are used
• Check solar panel open voltage range
• Check solar panel close circuit range
• Confirm all wiring connections are secure and tight
• Confirm all mounting connections are secure and tight Run Times

Run Times

Please refer to the runtimes chart to choose how much solar power your desired system requires. Note that all runtimes and ratings are approximate and may vary depending on your location and time of day and are based on 7 Hours of full sunlight a day.

11AMP Charge Controller

Intended Use

Any solar panel that is rated 12 watts or higher requires the use of a charge controller. Nature Power Solar panels and charge controllers come equipped with easy j-plug adapters. The 11Amp Charge controller is designed to protect your 12 Volt batteries from being overcharge by high voltage surges and prevents discharging of the battery overnight. LED lights display battery “Charged” or battery “Charging”. Never deeply discharge your battery; never let your battery voltage pass below 11.0 volts. It will cause permanent damage to the battery. Use a DMM Digital Multi-Meter to measure your battery’s voltage.
When connecting and during operation it is normal for both lights to flicker for a short time.
