What is solar power system?

Solar energy is the cleanest and greenest source of renewable energy generated electricity available to help 

power your home,  business or community buildingand nowadays the cheapest too! 

Grid connect systems tie in with your existing homeelectricity supply, ensuring you have all the electricity you

need, regardless of weather conditions and the time of day or night.   


Working Principle for On-grid & Off-grid Solar Power System


  Off / on grid          eco-friendly        money saving

2. Pure sinewave output suitable for most applications.

3. Green function for power saving.

4. Big surge rating can support Air Conditioning system.

5. Full protection inbuilt.6. Selectable battery type.

7. Ambient temperature up to 50 degree C support

8. Inductive motor load support



MPPT controller of solar power system


1. Using MCU and special software, based on the special software of the expert

 control system, realizes the intelligent optimization.SOC control.

2. The temperature compensation adopt external temperature sensor, the control 

accuracy is higher than the internal temperature sensor. 

3. Have the overcharge, discharge, electronic short-circuit, overload protection, 

unique counter-attack joint protection automatic control.

4. Adopt the tandem PWM for charging main circuit,make the charging loop voltage 

is reduce nearly half than use the diode charging circuit.Higher efficiency.

5. The intuitive LED iuminotron indicates the current battery status, allow users to 

understand the situation of use.

 battery with 3 years warranty for solar power system


1. No electrolyte leakage, battery swelling and cracking under normal use

2. With smooth discharging voltage and mild discharging platform

3. No leakage,swelling or cracking problem after one hour vibration

4. No leakage,swelling or cracking problem after 3 times of dropping.
