Off-grid solar power system

1. Working principle:

Off-grid Solar power system is that solar panel charges the solar energy after sunshine to transfer into the electric power and store in the battery, through the controller’s over-charging and discharging protection and invert transformation, supply to electric appliance.

2. Schematic diagram

 3. Specification

This system configuration is for reference, it can be adjusted based on actual condition and requirement.

4. Features of solar power system:

1. Off grid solar power system is mainly used for application with relatively-small power consumption, and the areas have no grid network coverage, or grid power is unstable or outage condition.  

2. It’s composed of solar panels, controller, inverter, battery bank, solar panel mounting racks, and other accessories required fora complete home solar power system.

3. The battery bank gives a stable power output to the solar inverter which converts DC to AC to power loads, and provides power backup in rainy or cloudy days.

4. The solar panels generate electricity at daytime and charge the battery bank .

5. The off grid home solar power system provides grid power bypass in case of battery power shortage when sunshine is not enough.

6. All the off grid home solar power system configurations are worked out by scientific calculation and design.

5. Details of solar power system:

6. Application range and product project cases :

1. Living house and home building

2. Office building, factory and warehouse

3. Shopping mall, venue, stadium and so on

4. Power station, field operation and some huge engineer construction.

11. FAQ

1. Q: Do you have your own factory?

    A: Yes, we have. Our factory located in Qingdao city, Shandong Province.

2.  Q: Could you print our company LOGO on the nameplate and package?

    A: Yes, we accept OEM orders.

3. Q: How do you overcome the anti-dumping and countervailing duties?

    A: We can use original Taiwan solar cells, and provide Certificate of Origin of Taiwan.

4. Q: Do you have solar project engineer who can guide me to install system?

A: Yes, we have a professional engineers team. They can teach you how to install a solar system.

5. Q: the orientation of the solar power system and install inclination?

A:solar power system installation general super to south (solar phalanx vertical and just south of the angle is 0), generating the largest. The inclination angle is the angle of the square plane and the horizontal ground, generally take the local latitude +10 degrees

6. Q:What are the influencing factors the efficiency of the solar power system?

A: solar power system power generation efficiency impact of many factors: the efficiency of the various components of the system, weather conditions, system orientation, system installation inclination. Any point of generation capacity there is a great difference
