Product Description

20KW home solar system energy storage power battery

 

SANDI Professional designed for solar power system

Large-scale off-grid solar power system can satisfy all the using of electricity for a family life. Nowadays, in the world wide, more and more countries use this type of generating system in remote village without electricity, telecommunication, pasture area, scenic resort, villas, islands, armies, school, hospital, private houses etc.

PV Off-grid Solar Power System

PV Off-grid Solar power generation system including solar panel array, solar charge controller, storage battery, Off-grid inverter, etc. In the sunshine, the solar panel convert the solar energy to DC power and charge the battery group by the charge controller. Then the off grid inverter convert the DC power into AC power for power supply the AC load.

The below solar system,solar kit and solar product available:                       

1.solar off-grid system 10KW-500KW.                                                                                                        

2.solar system can be designed according to different applications including houses,buildings,company,factory,farm,water pump,lighting.The system is designed automatically switch to grid power when battery power off ,then grid power will charge battery.When grid power not availabel,can switch to run on desiel generator  so as to continue  water pump irrigating or other application.

our company have produced soalar inverter, solar controller and PV combiner box for many years, With reliable quality and very competitive prices, we have exported products to USA, South America, Europe, India and Southeast Asia,and gotten good feedbacks from our overseas customers.

Our products from raw materials to finished products every process, every aspect of all strictly by professionals in order to ensure product quality. Also we can provide the certificate to ensure the quality of our productions, mainly CE, IEC, TUV ISO.

PV Combiner box with lightning protection

Solar charge controller

1) Adopt PWM multistep sequential limiting current charge method, auto control multiple solar array connection or shut off orderly according to the battery group voltage change tendency.

2) Adopt multiple-circuit charging-control circuit and individual killer switch on each circuit.

3) With auto protection function of over charge, electronic short circuit, anti-reverse protection. Prevent the battery group reverse charging to the solar panel array at night.

4) LCD screen shows the working status of solar panels, battery and controller. ( the voltage, current, power of solar energy panel and battery)

5) Power switch driving circuit is completely isolated from sampling circuit. The control signals is transmitted by opto isolation, with super-high disturbence rejection and stability.

6) Power switch driving circuit is completely isolated from sampling circuit. The control signals is transmitted by opto isolation, with super-high disturbence rejection and stability.

7) There are lightning protection device inside the controller. Limit instantaneous overvoltage which entered into solar panels under a level which the system can withstand; or unload the strong lightning current to the ground. To protect the equipment from lightning surge.

8) Adopts the industrial-grade chips for all control, which can work under the cold, hot, humi
