The Sol-Ark 12K falls on its face with 120v inductive loads. It’s an imbalance issue, but really caused by the lack of a transformer. Sol-Ark has stated that the 12K unit tops out at 2.5 HP. I have had luck installing autotransformers as well. The Outback PSX240 was my go to, but it looks like price of that has doubled in the past few years. Victron makes a 100A transformer for a fraction of the cost.
It seems like this issue has been resolved in the Sol-Ark 15K design, and I have yet to run into the same trouble.
