What is single phase and three phase system?

what is three phase power
what is single phase power
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.
The system can be 380V and 220V both.
R+S+T=380V,  R+N=220V, S+N=220V T+N=220V

PERC Technology

PERC stands for Passivated Emitter and Rear Cell. It improves efficiency by allowing electrons to flow more freely and also by increasing the reflectiveness of the back of solar cells. Increase solar panel efficiency.

Half-cut Cells Advantages

20kw 25kw 30kw off grid solar system-InkPV
(1)Reduced power losses
The solar cell is divided into two, 75% less electrical losses, increased overall current output of 2-4%. Make make the output power 5w-10w more than normal solar panel.

(2)Increased partial shading tolerance
When a solar panel is partially shaded, there are still 50% space can generate power. But for tranditional solar panel, its 100% no power output.

(3)Reduced hot spots and temperature
Half-cut solar cells reduce the current per substring, this technology can reduce the peak temperature of hot spots by up to 20ºC.
