TMDSSOLARUINVKIT, AC output current spikes at zero-crossing

I connected the TMDSSOLARUINVKIT to grid 230Vac, 50Hz and this is the waveforms of VGRID_SEN and AC output current.

Could you advise to reduce spikes of AC output current at zero-crossing?

Klanarong,

The spike comes because of the 60Hz switch change,

Some strategies can be used, however i am not familiar with those. If i knew i would have implemented those on the design already :)

but below are some pointers
