Rollands Plains farm off-grid solar solution

Harelec were engaged to provide an off-grid solar solution for this farmer, who was previously using diesel to power his home and farm. The system needed to be large enough to supply quite high demands during the day, with lower power requirements throughout the night, however with plans to expand and add accommodation facilities in the future, the system needed to be designed to accommodate the addition of more batteries at a later date.

The end result was a unit custom-built by Harelec, comprising of 2 x SMA Sunny Island battery inverters; 4 x SMA Sunny Boy inverters connected to 26kW of solar PV panels; 8 x BYD lithium ion batteries, and full monitoring via ethernet to the internet.

This system is able to provide continuous power of 12,000W, 5 mins of surge power of up to 18,000W, and can produce in excess of 100kWh of clean, green solar power per day.
