AERL EarthGuard Ground Fault Detection - EG-600:
The EarthGuard EG-600 is a standalone device
for integration with approved third-party controllers,
power conversion equipment and battery systems.
Utilizing proprietary detection techniques, the AERL
EarthGuard Insulation Monitoring Device simultaneously
monitors up to two circuits (20 - 600Vdc) for conductor
insulation degradation.
The EarthGuard EG-600 monitoring device satisfies
the earth fault detection requirements of both
AS/NZS 5033:2014 & AS/NZS 5139:2019 with onboard
audio/visual alarms, and alarm relay outputs for
external fault indication.
The AERL EG-600 allow for PV arrays up to 600V (not a major thing for Victron), and also have two separate monitoring channels (either two PV, or one PV and one battery side).
