Working on feeding a couple of plastic injection molding machines in my barn. I'm currently setting up a solar system in the barn (20 kW of panels, 30kWh of batteries, Solark 15k) but need to feed the 8 hp 3 phase motors on the machines. I don't have 3 phase available from the grid. I do have a 100 amp 220 v feed off the grid to support my power draw. The machines also have heaters I need to feed so I'm going to need roughly 20kW to feed them.
I can't use a split phase feed VFD as there seems to be a rather hard limit of 5 hp for using a 220 single/split phase input, and it would exceed what I can get off the inverter I have. The solar installer I'm working with has no knowledge of 3 phase so I'm doing the research on this.
What's available in the US that will support 3 phase off grid? For right now I'm planning on running it off the batteries with the Solark handling the PV, but as it's already at capacity I will use the MPPT inputs if I expand the PV.
