Price:
Sale price$733.00

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.
