What output do you need?

What is the difference between single phase and three phase appliance?
what is single phase power
Single phase: 110V/120V/220V/230V/240V ±2%
what is three 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.

  • Our off-grid power systems have highly advanced inverter and charger technology.
