I have the 4 KW Mecer unit installed off-grid on a farm. The PDF document the supplier sent me ( no manual in the box) lists the max PV as 95 V open circuit but on this forum and some websites it is listed as 145V?
So as a result I connected my four 200-250W panels in series and parallel to 60V(to not exceed the 95V I was given)(70 V measured). The problem is the Mecer at no time quantifies the PV array at greater than 600W input even in full direct sun. Why not? Is the MPPT fully functional? at 145V allowable I can connect the panels all in series and try again but have not yet.
