20kw Home Hybrid Load off Grid Power Inverter Solar 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.
Here is the 20KW solar off grid home system, 15kw load with 8 hours supply for your reference.
1.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, Australia 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.

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.
