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.
This solar power system solution is just for reference. It can be adjusted based on actual condition and requirement. All parts have been tested and proven in actual operation with enough reliability and stability. It ¡s suggested to source whole system as a package from us to guarantee the system compatibility.
1)High reliability with guaranteed +/-3% output power tolerance
2)The modules can withstand high wind-pressure, snow loads and extreme temperatures
3) Bypass diodes to minimize power loss with shading
4) High and stable conversion efficiency to ensure the highest quality
Quality and Safety:
* Industry leading power output warranty, 25 year 80%, 10 year 90% power warranty
and 5-year power warranty of materials and workmanship
*CE, TUV, ETL, ISO9001:2008 (Quality Management system) certified factory Product Quality warranty & products Liability Insurance to guarantee and user' benefits.
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.
