What is the Hybrid Mains Complementary Solar Street Light principle?

Hybrid Grid power complementary solar-led street lights, or we may call it on-grid solar-led street lights can solve the problem of insufficient solar light in high latitude areas and the long rainy season in many areas. Compared with the common solar street lights, it solves the problem of light-off caused by rainy days and insufficient light. Both systems have their own advantages and disadvantages. And such technology could be also used in all in one solar street lights, solar parking lot lights, and solar power systems.

Solar panel convert in power through the charger to the battery to save electricity, center control at any time to collect information about the battery, avoid excessive charging and discharging, the maintenance the battery; At night when the battery power savings by an inverter into 220 v alternating current to the lamp power supply.

The technology used by the grid power complementary solar street lights is not a traditional grid-tied technology. It does not upload solar power to the grid. Its grid connection means that when it encounters a long rainy day and the solar power supply is insufficient, it switches to the grid power supply.

The difference between common solar light and the  hybrid complementary solar street lamp

The difference between common solar lights and the solar energy complementary solar street light is that the city electricity complementary solar street lamp needs to connect a group of electric power cables to the controller, and needs a transformer to convert grid AC electricity to suitable DC and the power supply is converted to the power supply when the battery is short of power.

The main advantage of a hybrid complementary solar street lights

1. High-power solar street lights are available

2. Strong environmental adaptability for solar street lamps

3. Do not need high requirements for batteries, solar panels

The main disadvantage of a hybrid complementary solar street lamp

1. Need cable and complicated installation

2. Additional switching power supply and constant current source are required

There are 2 types of Hybrid Mains Complementary Solar Street Lights

1.  220V to 380V city electricity as main power, when it is cut off, the solar power starts to supply energy as a backup emergency light.

2. Solar Power is the main power, When it has a long rainy day, and the battery has low energy, the 220V city power starts to supply energy.

(90% of the market use this solution, solar power as the main power could save a lot of electricity cost)

Hybrid Mains Complementary Solar Street Light Application Case

We will introduce a kind of solar street light with grid power complementary. Its main function is to switch to grid power when solar power is insufficient. In this way, when experiencing a long rainy season, or in areas with insufficient light at high latitudes, solar street lights can function well without the lights shut down.

Complementation of 220V city electricity solar street lights is widely used, In some important roads or highways, the lights are not allowed to be turned off. People either use solar energy as a backup emergency light or use 220V city electricity as a complementation.
