An Analysis Of The Reasons For The Decline Of Solar Garden Light

If you have installed the solar garden light, and the normal use of a period of time, first check the controller's light response, if the two lights are not bright, the controller may have been damaged, there may be a strong current shock , Such as direct lightning or short circuit and so on.

If the controller light shows the normal discharge at night, the battery has enough voltage, but the Solar Garden Light is not bright, the positive and negative pole directly connected to the battery positive and negative test, if not discharge, the lamp drive or rectifier There may be damage.

The controller shows the undervoltage condition, no light after dark, but the battery voltage has exceeded the undervoltage value, indicating that the battery is powered. 24V system, the undervoltage protection value of 22.2V (controller default) or so, the battery drops to this voltage point after the controller turns off the power, stop the discharge, mainly to protect the battery is not over-discharge.

Solar garden light panel to recharge the battery during the day, the voltage charged to 24V (controller default), will continue to discharge, the main purpose is to avoid the battery is often damaged by the depth of discharge. Then the battery undervoltage, if not restart the controller, 22.2V-24V are between the undervoltage state, must be charged to the battery voltage is more than 24V will continue to discharge.

Today, people are increasingly aware of the protection of the environment, also will promote low-carbon environmental protection, so that the use of new energy solar energy more and more popular. Solar garden light are a very good application case of using solar energy.

1, energy: solar garden light using solar photovoltaic cells will be the sun's light energy conversion to provide electricity, solar energy as a green new energy, "inexhaustible", make full use of solar energy resources, to ease the conventional Energy tensions have a positive meaning;

2, green: no mercury and xenon and other harmful elements, conducive to recycling and use, and will not produce electromagnetic interference (ordinary lamp contains mercury and lead and other elements, energy-saving lamps in the electronic ballast will produce electromagnetic interference) ;

3, safety: solar garden light required voltage, current is small, less heat, do not produce security risks, no electric shock, fire and other accidents can be used for mines and other dangerous places;

4, convenient: solar garden light to install simple, convenient, do not need as ordinary street lights as the line, digging construction and other large infrastructure projects, there is no power outage concerns;

5, long life: semiconductor chip light, no filament, no glass bubble, not afraid of vibration, not broken, the service life of up to 50,000 hours (ordinary incandescent lamp life of only one thousand hours, ordinary energy-saving lamp life only eight Thousands of hours)

6, low maintenance costs: solar garden light use the sun power supply, according to the lighting time and rainy days the design of solar panels and battery power and capacity, the entire system are running automatic control, without human intervention, an investment, long-term use.
