Definitely keep your eye on it with a true RMS meter and your THD meter. I wouldn't do anything yet until the panel is a bit more loaded.
You'll find as more load is added, they begin to cancel each other out. Non-linear power supplies draw power when they want. With enough load eventually they start to draw at such "randomness", that the effective THD reduces.
Also be sure that you are using a clamp-on that is somewhat close in size to your load, so as to increase accuracy of the measurement. Some clamp-on's that are designed to measure 1000A, don't measure 14A very accurately.
