In Sydney, Australia, the latest advancements in sustainable energy have been showcased at the Smart Energy 2025 expo, featuring innovative solutions from Swatten, a subsidiary of Sieyuan Electric. At booth 58, Swatten made a striking appearance, coinciding with the event’s launch. The company’s commitment to sustainable energy solutions was reinforced by the Australian government’s Cheaper Home Batteries Program.
- Minister for Climate Change and Energy, Chris Bowen, reiterated the program’s 30% subsidy on home energy storage systems, saving new solar homes up to AUD 2,300 annually and existing solar households an additional AUD 1,100.
- The program aims to permanently reduce energy bills for Australian households, providing significant cost-saving opportunities for over 4 million homes already equipped with solar.
Swatten’s Single-Phase Hybrid Inverter (8/10kW) is designed for high-demand homes and small businesses. Key features include:
- 50V ultra-low startup voltage for early activation in low-light conditions
- 200% DC input oversizing for greater PV capacity
- 4-MPPT design for optimized energy capture
These features enable the inverter to handle high-load demands, including EV charging and air conditioning, reducing reliance on the grid.
