Earth fault alarm
Just below the MPPT, is the Earth Fault Alarm display. This monitors the unearthed PV Array (60-
300Vdc) and battery storage system for conductor insulation degradation. It satisfies the earth fault
detection requirements of both AS/NZS 5033:2021 and AS/NZS 5139:2019 with onboard audio/visual
alarms and an alarm relay output for external fault detection.
This device consists of two parts, the display interface
located under the MPPT in the face plate, and the
electronics section which in installed in the
communications compartment.
The ALL-CLEAR light is illuminated in normal operation.
If the device detects a fault, the FAULT DETECTED light
will illuminate and a buzzer will sound that can be muted
by pressing “Silence”. Contact your installer.

Communications compartment
The communications compartment contains
the remote monitoring equipment and the
electronics section of the Earth Fault alarm.
It is located on the right side of the
HoneyBadger and is accessed by removing
the four screws holding the vent cover in
place.
The RedPi Lite monitoring equipment
installed consists of a RUT240 modem with a
RedEarth SIM-card for remote monitoring.
An antenna is included which should be
mounted externally during installation.
Additional Wi-Fi and mobile antennas are
connected directly to the modem, however
for optimal coverage the external antenna
should be installed outside the unit. Ideally in
a high location with clear visual access to the
outside. The antenna has a magnetic base to help with positioning.
