Ground Fault Sensitivity

The SRX-R ground fault detection offers three levels of sensitivity, all of which are compliant with the Australian PV
installation standards.

Low

100kΩ

Medium

50kΩ

High

30kΩ

The sensitivity of the ground fault detection can be configured in AERL Link as demonstrated in

Figure 11

below.
