Product Description
Utilizing proprietary detection techniques, the AERL EarthGuard Insulation Monitoring Device
simultaneously monitors the unearthed PV Array (60 - 300V) and Battery Storage System (48/120V) for
conductor insulation degradation.
Installed on the battery bus, the EarthGuard monitoring device satisfies the earth fault detection
requirements of both AS/NZS 5033:2014 & AS/NZS 5139:2019 with onboard audio/visual alarms and an
alarm relay output for external fault indication.
Featuring support for full integration with AERL’s CoolMax SRX charge controller range, EarthGuard can be
utilized in an integrated arrangement or as a standalone device for use with approved third-party
controllers, power conversion equipment and battery systems.
Firmware
This installation and operation manual covers EarthGuard Firmware Revision v1.1.
