Nyangumarta Warrarn Rangers Do Really Important Work

For some years now we have supported initiatives such as “Create Ranger Parks” and “Country Needs People”, which aims to create an extensive network of national parks, managed by Indigenous Rangers in Western Australia. It’s one of those things that just makes perfect sense for the land, ecology, for Indigenous people, their communities and tourism. It’s a win at very turn.

So we were quite excited when asked to build an RV Lithium Battery and Solar System to power a work Trailer built by Wandering Star, for the Nyangumarta Warrarn Indigenous Rangers from Bidyadanga Aboriginal Community.


Nyangumarta Warrarn Rangers do really important work managing 28,420km2 of the Nyangumarta Warrarn Protected Area which extends 310km inland to the east through the Great Sandy Desert, from the coastline of the Indian Ocean at Eighty Mile Beach.

To read all about their wonderful work, please click here to read their June 2018 Newsletter.

Another fantastic resource we found online is a publication of “Traditional Ecological Knowledge of Nyangumarta Warrarn Indigenous Protected Area”. It describes the area including Eighty Mile Beach, the language and vegetation and traditional uses by Indigenous people, thanks to a list of contributors including Elders and the Nyangumarta Warrarn Rangers.

To assist the Nyangumarta Warrarn Rangers with their work, the trailer was built to carry equipment and resources.

To the trailer we installed:

  • A Victron BMV712 Smart Battery Monitor with Temperature Sensor and Bluetooth connectivity.

  • An RVLSA 30A Lithium DC Charger, charged from the tow vehicle via an Anderson 50A plug.

  • 1 x LG Neon 320W Solar Panel

  • An RVSLA 220A BCU (Battery Control Unit) with separate charge and load protection, which allows the battery output to be automatically switched off when the battery is in a low state of charge but still allows the battery to be charged. The BCU then allows the battery output to be automatically turned back on when sufficiently charged.

  • The BCU protects the battery from charging too high and discharging too low, from operating in too high and low temperatures, from over currents and short circuits.

  • The BCU also protects the battery load from low battery state of charge, high and low voltage, high and low temperature, over current and short circuits.

We wish the Nyangumarta Warrarn Rangers all the very best in their endeavors and thank you for the fantastic work you do. We’re sure you’ll enjoy the new trailer and facilities!
