The Growatt inverters are top quality, they ship a huge amount of inverters. They make US models in split phase. What happened here is the client ordered something he knew nothing about from a vendor that also knew nothing. I run into this all the time. That's what we get the big bucks for. We buy a lot of chinese inverters for different islands. If we want 230V 2 wire to suit the island, that's what we order. In some cases we order 120V, some are 240V split phase, and some are 230V. If it's off-grid, will there be a requirement for UL listing? I would not worry about the quality of the inverter, they are excellent. I would worry about the design. If you are not confident, walk away. You will be expected to make it work or keep trying, and the damage to your reputation if it all fails will be hard to counter. The client is never wrong.
