Off Grid Solar Power System 5KW/10KW/20KW/50KW/100KW
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.
Can design solar system according to your requirement and your local solar condition,used for house,office,factory,farm,etc.
The below solar system,solar kit and solar product available:
1.solar off-grid system 5KW-250KW.
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.

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, humid conditions.
GEL battery is mainly made up of positive and negative plates, special diaphragm, deep electrolyte, battery shell and security valve and so on. Through colloid technology, the electrolyte is fixed in solid state in battery. The advanced AGM battery had greatly improved the cycling performance (cycling increased 80%) by adopting the unique grid alloy and the high-density lead paste formula The Deep Cycle series are specially designed for applying in solar energy photovoltaic power system.
Off Grid Solar Inverter
1, Two kinds of start mode: Reduction Voltage Start and Variable Frequency Start. Customers can set start mode according to the nature of their load.
2, The output frequency can be set, this function is very convenient for customer.
3, The output voltage can be set between +20 % to -40 % of rated voltage. It’s a great convenience to users.
4, The DC input voltage range can also be set. Over-voltage point, under-voltage point, over-voltage recovery point, under-voltage recovery point all can be set via the LCD panel. Convenient for increasing or reducing the quantity of batteries, photovoltaic modules also can be used flexibly.
5, Pure sine wave output. with good transient response less than 40MS, little harmonic distortion, higher conversion efficiency and stable output voltage.
6, Powerful data display and fault instruction function. LCD can display the DC input voltage, output frequency, phase voltage, phase current, AC bypass input voltage, output power KWH, time and date, temperature, fault code display.
7, Using the fifth generation efficient IPM intelligent module from Japanese Mitsubishi, high efficiency and stable performance. It with powerful protection function, the protection for short circuit, over load, over temperature is more safe and reliable. It’s service life can up to 15 years or more.
8, Wide input voltage can be set according to customer’s requirement. Input voltage range can be selected from 100-500V or 200-850V.
9, Product have passed the European CE (EMC and LVD) certificated and accredited by Australia CEC energy network.
