I run my entire shop off grid with an ampint 6000w low frequency split phase inverter. Runs all the lights, saws, drill press, air compressor, grinders, and yes, my welders and plasma cutter. Was about $10,000 cheaper than having grid service put in up front (in my situation I couldn't branch power from the house) , plus all my power is free for years to come. The weirdest part is when the grid power is out to my house, I can just go out to the shop and everything works as normal😂
