15kw off grid inverter built-in charge controller

Inverter technical:

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.

Controller technical:

◆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.

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

◆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.

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

◆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.

◆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.

◆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.

◆Adopts the industrial-grade chips for all control, which can work under the cold, hot, humid conditions.

◆Temperature compensation function. Compensate the temperature according different battery type.

◆Fixable communication solution with RS-232,RS-485,USB,GPRS,Etherner,etc.
