General Wiring

This product can be connected to the car battery in two different ways.

  1. Cigarette lighter Connection

Connect the cigarette lighter + SAE cable to the solar panel’s SAE plug and plug the cigarette lighter connector into the vehicle’s cigarette lighter port to charge the vehicle. (This works with the majority of vehicles).

Testing and Troubleshooting

Testing
Check the open-circuit voltage (Voc) of every module, using a digital multimeter. The measured Voc should correspond close to the Vocs of the module parameter. You will find the rated voltage in the technical specifications of the specific module. If the measured value is significantly lower than the expected value, proceed as described under “Troubleshooting an low voltage”.

Troubleshooting a low voltage
To identify the commonly low voltage and excessively low voltage, the commonly low voltage mentioned here is the decrease of open-circuit voltage of the module, which is caused by the temperature rising of solar cells or lower irradiance. Excessively low voltage is typically caused by improper connections of the terminals or defective bypass diodes.

  • Check the open-circuit voltage with multimeter
  • If the measured voltage is only half of the rate, this indicates a defective bypass diode. By replacing or remove the diode, the issue may be sorted. Removing the bypass diodes should only be done by a competent PV technician and the module has to be disconnected from the system.

FAQ

Why is the indicator light still on after I disconnected the panel?

The indicator light will be on as long as there is a power supply, when the panel is still receiving sunlight and converting it into electricity even after disconnecting the connection to the cigarette lighter. After the panel stops receiving sunlight or is placed in a dark place, the indicator light will slowly turn off.

Why can’t I charge the car battery by the cigarette lighter?

For some brands and models of vehicles, the circuit between the cigarette lighter and the battery is disconnected when the ignition is off, such vehicles are not suitable to be charged by cigarette lighter port.

Why does the vehicle’s battery voltage keep dropping?

Put the panel in the sun and use a multimeter to test the
output voltage and current of the panel respectively. The normal panel output should be 12V, 0.3A (5W)/ 0.5A ( 10W). The panel will not produce much output without directly sunlight, so make sure that the vehicle or panel is placed in a sunny place.

Maintenance

The following maintenance is recommended to ensure optimum performance and longevity of the solar panel:

  • Clean the glass surface of the solar panel when necessary. Always use
  • ter and a soft sponge or cloth for cleaning. A mild, non-abrasive cleaning agent can be used to remove dirt.
  •  Check the electrical and mechanical connections every six months to verify that they are clean, secure and undamaged.
  • Inspect the solar panels and make sure the surfaces are free from dust,
  • irt, and other debris; clean with a wet cloth or glass cleaner if necessary.
  • Check to make sure all structural components, mechanical fasteners, and electrical connections are secure, clean, and corrosion-free.
  • Check and replace damaged components if necessary
