- Hello everyone,
After installing a 3-phase AC coupled system with 6 quattros an a PV inverter connected to AC out of Quattros, we realised that the Quattros cannot connect to grid (AC in1) when the grid operator swap 2 phases. The problem is that the grid operator often swap phases during maintenance of electrical network, and after which the quattros cannot connect anymore to Grid when energy comes back. Is there anyway to change setting of quattro so that they can still connect to grid even if the operator swap 2 phases?
