Low insulation impedance
I've got 2 strings of solar, pv1 has 16 panels (2 rows of 8 in series which then connect in parallel). Pv2 is 11 panels ran in series.
The impedance on pv2 is 12000 k ohms.
The impedance on pv1 is 660 k ohms.
I've checked ground fault on pv+ and pv- on pv1 and there's no fault.
This has been like this since installed.
Is it worth getting it looked at?
