What is three phase system?

what is three phase power
80kw solar system price-Inkpv
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



  • We have installation manual and electrical diagram. Follow the our installation guidance step by step, the installation can be done by your self. Contact us for 80kw solar system.
