On August 30, 2023, the second China International Energy Storage Exhibition grandly opened in Suzhou, Jiangsu. At this grand event of the energy storage industry, Sinexcel made a splendid appearance with its industrial and residential storage products, becoming a major highlight of the exhibition. At this exhibition, Sinexcel ISUNA, the subsidiary of Sinexcel, launched two heavyweight energy storage inverter products: iSUNA single-phase residential energy storage inverter 3-6kW and iSUNA three-phase residential energy storage inverter 10-20kW, showcasing the new technical direction of the industry.
Leading Technology, Leading the New Future of the Industry
Silicon carbide technology is a major breakthrough for Sinexcel in improving product performance. The residential storage R&D team fully utilizes the characteristics of new materials and technologies to enhance efficiency, reduce losses, and make the product operation more stable and reliable.
New Generation SiC Technology, More Efficient and Stable
Compared with silicon materials, silicon carbide materials have smaller conduction resistance of semiconductor switches, faster opening and closing speeds, thus reducing losses in the switching process and improving the efficiency of the entire module. Sinexcel ISUNA has broken through technical difficulties with full silicon carbide material switch technology and reasonable device selection design, achieving a machine efficiency increase of 98.2%.
Compared to silicon switches, switches made of full silicon carbide material have a wider bandgap, allowing for the design of blocking voltages up to 15kV. Silicon carbide has over 10 times the pressure resistance of equivalent silicon devices; the enhanced pressure resistance of power switching devices improves the reliability and stability of equipment operation.
High Compatibility, Worry-Free Expansion
The iSUNA residential storage inverter boasts excellent high compatibility, supporting up to 15 parallel expansions. Multiple inverters can operate stably in sync, easily handling both small household electricity and large industrial and commercial electricity, meeting the needs of different application scenarios.
Customer-Centric, Pursuing New Quality Peaks
Sinexcel ISUNA always puts users first. Each technological innovation stems from a deep understanding of user needs and an unremitting pursuit of quality. The iSUNA residential storage inverter provides more comprehensive solutions to the industry's difficult problem of mixing different brands and ages of batteries. It also brings higher experiences to users in terms of three-phase imbalance and intelligent APPs.
Two Independent Battery Ports, Support Mixture Use of Old and New Batteries
The iSUNA residential storage inverter adopts a two-way battery branch design, and each battery branch can be independently managed. The mixing of new and old batteries and different brand batteries is an industry problem. The current industry solutions are all achieved by adding DC-DC modules, which require additional costs. The independent management design of the iSUNA residential storage inverter's two-way battery branch not only improves battery usage efficiency but also enhances system stability and safety. It solves the problem of using different brands and new and old batteries together, making the system more flexible without adding extra costs.
100% Support Three-Phase Imbalance
In traditional energy storage inverters, three-phase imbalance load is often a difficult technical problem to overcome. However, the iSUNA residential storage inverter can achieve 100% support for three-phase imbalance load, ensuring that the output voltage difference is kept within 5%, better protecting the battery and load, bringing greater convenience and a higher usage experience to users.
Intelligent Monitoring, Reducing Electricity Costs
Equipped with an intelligent APP, you can set six battery charging and discharging time points, intelligently adjust the battery charging and discharging time according to electricity price changes, help users peak shaving and valley filling, reduce electricity costs, and achieve the maximization of economic benefits.
Sinexcel with its own R&D strength and industry experience, has always stood at the forefront of the industry. In the future, Sinexcel ISUNA will continue to adhere to technological innovation, provide more advanced and stable residential energy storage products and solutions for global users, and make greater contributions to promoting the large-scale application of clean energy worldwide.
