<p class="MsoNormal"><span style="COLOR:#44546a">Did you ever make any progress on this issue? We’re having an interesting issue with one of the new Sunny Tri-Power inverters (a 24 kW unit in this case) where we get an error “residual current too high.” We’ve only done a little troubleshooting so far but I don’t think we have a ground fault. </span></p>
