What output do you need?

What is the difference between single phase and three phase appliance?
10kw home solar system
Single phase: 110V/120V/220V/230V/240V ±2%
10kw home solar system
Three phase: 380Vac/400Vac±10%(customized 190Vac/200VAC)
  • For most home appalinces, the voltage is single phase. Like fans, lights, TVs, ect.
  • For commercial appliances, the voltage might be three phase, like big power pumps, commercial air conditioner.
  • Off grid system is usually composed of solar panels, connector, inverter, battery and mounting system.

  • The solar system is designed with the conformation of one or more solar panels, mechanical hardware, and electrical component utilized to produce electricity from the sun's energy. Solar systems are power systems that convert sunlight into electricity by utilizing the photovoltaic effect.                                                                     
  • This is a process in which semiconducting materials generate voltage and current when exposed to light. Solar panels are installed for the conversion of thermal energy into electricity, while solar panels convert solar radiation into heat. This is why these solutions do not compete with each other. Instead, they may complement each other.

  • When the sun shines onto a solar panel, energy from the sunlight is absorbed by the solar cells in the panel. This energy creates electrical charges that move in response to an internal electrical field in the cell, causing electricity to flow.
  • Electricity produced by solar cells is clean and silent. Because they do not use fuel other than sunshine, solar systems do not release any harmful air or water pollution into the environment, deplete natural resources, or endanger animal or human health. Photovoltaic systems are quiet and visually unobtrusive.

Types of system

Off-grid solar system

Off-grid system is suitable for areas without grid-connected or unstable grid-connected power, composed of solar panels, connector, inverter, battery and mounting system.

On-grid solar system

On-grid solar power system connects to the power grid, can sell excess electricity to the public grid.

Hybrid solar system

Hybrid Solar System combines advantages of on grid solar system and off grid solar system.
It connects to grid, you can sell solar power to grid or use directly.
If grid stop, battery supply power.

Solar and wind system

If your place enjoy good wind speed, the wind turbine can be a very good power source. It can give you unstopable power 24hrs. With solar and wind power, your home can be 100% off-grid.
