DC Insulation Resistance of PV Systems
Most international and national standards dealing with personal protection, require that fault currents do not exceed 30mA (also the reference value of the standard IEC 62109-2 for inverters). Of course, it is always allowed to use a higher value for R iso than stated in the standards, as this may increase the safety of the PV system.
