InkPV commercial power system
Solar power made affordable and simple
Brand: InkPV or OEM
Wattage: vestwoods 12kw battery powerwall
Type: Off-grid with battery back up
Output voltage: Single phase or three phase

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 pump, commercial air conditioner.
