How do I power a communications site with no grid connection?
Australian practice is a DC-coupled solar hybrid: PV array, MPPT charge control, LiFePOâ‚„ or gel storage, an optional generator, and remote monitoring. The sizing conversation starts with the site’s measured 24-hour consumption in kWh, the worst-month solar resource at that latitude, and the autonomy the network requires. Note that where a comms site is not in the scope of AS/NZS 5139, telecommunications is expressly excluded, the applicable design references are AS/NZS 4509.2 for sizing, AS/NZS 5033 for the array, AS 3011 and AS 2676 for the battery installation, and AS 4044:2024 for the charger.
