Walnut Energy: Battery solutions for commercial, industrial & grid-scale applications

Walnut Energy is an Australian developer of containerised battery storage solutions for medium to large-scale commercial and industrial premises – not to mention power plants and microgrids. Their battery storage products can be deployed in on-grid, edge-of-grid and off-grid applications to deliver a range of capabilities which include storing energy, providing black out protection, voltage and frequency regulation and more.. The company is closely partnered with Narada, one of the largest manufacturers of batteries in the world.

On the hardware side, Walnut Energy’s products can be sourced as both turn-key solutions (including inverters, management systems and monitoring functionality) as well as more modular ‘core modules’ (with inverters, management and switch gear to be provided by third parties). The company can be engaged as a simple hardware provider or as both the provider and long-time servicer of the products delivered.

Battery technology

Walnut Energy’s storage solutions incorporate lead carbon and lithium-iron phosphate (LiFePO4) batteries from Narada, one of the largest battery manufacturers in the world. Depending on the application, demands and budget of a site/client, Walnut Energy is able to ‘balance’ the lead carbon/LiFePO4 battery ratio to deliver optimum value and performance.
