Off grid avocado farm completely self-sufficient for 660 days

Toxicant Materials and Alternatives in Electronics
Battery storage manufacturer Tesvolt and project developer Unlimited Energy were awarded "The smarter E Award" for a project realized in South-West Australia. The avocado farm in Pemberton has already been operated on battery power only for the last 660 days. The energy concept for the farm includes a 53 kilowatt (kW) photovoltaic system that simultaneously feeds a 160 kWh saltwater battery system as well as a 48 kWh Tesvolt energy storage system. The farm is completely self-sufficient and is operated without connection to the power grid. For more information see the IDTechEx report on off grid zero-emission electricity.
 
"People want sustainable and organically grown food. The avocado farm proves that climate-neutral production is possible even in the outback," says Daniel Hannemann, Commercial Director of Tesvolt. "We are proud to be part of this project and that our technology makes a significant contribution."
 
100 percent self-sufficiency in a demanding environment
The avocado farm in South-West Australian Pemberton produces 90 tons of avocados annually on 5 hectares, which are sold regionally. The fruit, which need a lot of water and sun to develop their optimal taste, are supplied with water using hydraulic water pumps from underground water tanks during the hot and dry Australian summers. These fill up during the very rainy winter season.

"The whole system would not function without the high performance of the Tesvolt energy storage solution," says Unlimited Energy CEO George Zombori. "Above all, a fast charging and discharging speed was important to us to allow for the water pumps to start up. While the Tesvolt storage system absorbs peak loads, the salt water battery system takes care of the base load. "As a matter of fact, the Tesvolt system could do all the work," says Zombori.
 
Simple plug and play installation
Although only as large as a refrigerator, the Tesvolt storage system provides 940 amps for peak-load periods. Tesvolt uses prismatic high-energy and high-performance lithium-based cells in its batteries. A fast discharge of up to 4C for a short time is possible, which makes the system particularly suitable for commercial operations.
 
The entire Tesvolt system was installed within 20 minutes using the simple plug-in system. "The plug-and-play principle has saved us and the installer a lot of headache," says Zombori. For a region in which certified technicians are rather rare, this is a major advantage for future projects".
