Its more than enough Bryan. I replaced a 90 sq mm dual core primary with 25 sq mm welding cable. That's good for a conservative 100A and that it would only see for very short (startup) times in my set up. Back in the days I started building these inverters bigger was better when it came to primary windings, have since found out that the fat primary can contribute to spectacular blow ups if one is unlucky .
