After installing a grid tie inverter (GTI,) the power factor dropped from 1 to .85 over the last week. My loads are a combination of inductive and resistive.

I have an option of setting my GTI to feed .8 lag or .8 lead.

Which one should I use?

The default setting is unity.

I understand why the drop but what can I do about it?

My utility mandates a PF of .9 at least

Set it to 0.8 lead for improving the overall power factor
