The global energy transition is reshaping electricity use worldwide. Households and businesses are increasingly adopting solar and storage to ensure energy security, cost efficiency, and maintain uninterrupted power in regions prone to outages. To meet these evolving needs, Swatten’s products provide professional, dependable support for residential and commercial storage—built around 7 design principles that deliver smarter, safer, and more reliable energy.
1. Make it Universal
Swatten systems are certified in 16 countries, ensuring seamless deployment across diverse markets. Their integrated design simplifies installation and commissioning, saving time and cost. Compatible with both DC and AC coupled solar systems, new or existing setups can connect easily—making energy solutions worry-free for installers and reliable for users.
2. Built-in On & Off Grid
Swatten’s hybrid inverters switch seamlessly between on & off-grid modes in ≤10 ms, keeping essential appliances such as refrigerators and ventilators powered during outages. In on-grid mode, they deliver up to 55 kW bypass output and 20% higher power density than comparable products, powering high-demand appliances in a compact, robust design. Built-in functionality eliminates the need for an extra backup box, reducing installation time and costs. 3. Battery Ready
Swatten supports a “start now, upgrade later” approach, allowing single units to expand up to 102.4 kWh. This flexibility lets households begin with solar and add a battery as needed. For example, a family in Portugal first installed a Swatten inverter and added a home battery a month later to achieve full self-consumption. Whenever users are ready, Swatten is ready.
4. Go Fanless
Swatten’s fanless inverters, designed with optimized hardware and thermal management, keep noise below 35 dB across all models, even while supporting high-load operation up to 20 kW. This silent design reduces mechanical wear and dust accumulation, enhancing long-term reliability and lowering maintenance—quietly safeguarding household electricity and comfort.
5. Maximize DC Input Swatten single-phase hybrid inverters support up to 330% DC oversizing and 50 V low start-up voltage, maintaining full power even in low-light conditions. This increases daily battery charging by up to 30%, storing more energy on cloudy days and maximizing use in sunnier regions—keeping critical loads running longer.
6. Maximize Off-grid Output
In off-grid mode, all Swatten products deliver stable operation across diverse appliances. At the same time, single-phase units provide up to 280% peak output for 10 seconds—keeping refrigerators, air conditioners, pumps, and medical devices reliably powered.
Guided by 7 design principles, Swatten turns complex energy challenges into simple, reliable solutions—keeping homes bright, families comfortable, and businesses running smoothly. Backed by Sieyuan Electric’s decades of expertise in delivering safe, dependable energy from power plants to end users, our users enjoy Smarter Power, Better Life every day.
