Sunways, formerly known as Sunways AG founded in Konstanz, Germany in 1993. With 28 years of PV industry experience, Sunways develops, produces, and distributes string inverters for on-grid PV systems and energy storage systems, data communication solutions, and accessories for monitoring and managing.
Recently, Sunways has launched a new series of single-phase high-voltage hybrid inverters for applications in residential roof-top projects. This series line up includes STH-3KTL-HSS, STH-3.6KTL-HSS, STH-3KTL-HS, STH-3.6KTL-HS, STH-4.2KTL-HS, STH-4.6KTL-HS, STH-5KTL-HS, STH-6KTL-HS, STH-7KTL-HS, STH-8KTL-HS in a total of ten models, and among these ten models the postfix with -HSS is single-phase with a single MPP tracker and the postfix with -HS is single-phase with two MPP trackers. All of them feature a conversion efficiency of 97.6% which is at the top level of the market. With this new hybrid series launching, Sunways now have a hybrid power range from 3kW to 12kW (STH 4-12KTL-HT three-phase hybrid), lead the pack in power ranges.
“Our STH 3-8KTL-HS series hybrid inverter has featured a series of most advanced technologies making it one of the most powerful and intelligent hybrid inverters in the market,” said Mr. Kui Li, Sunways’ global VP of sales and marketing. These include:
1. Super wide battery voltage from 85-500V makes the connected battery storage capacity ranging from 5.12kWh to 20.48kWh and optimizes the self-sufficiency rate up to 100%.
2. Seamless power transition from on-grid mode to back-up mode(within 10ms) to protect against household loads damage when power outages.
3. Industry-leading level heat-dissipation technology makes the inverter operation temperature 5-10 celsius lower than others, even if no cooling fans are integrated.
4. Best-in-class components widely used in entire products and constant software improvement granted our inverters a longer lifespan and safety and reliability performance.
5. 110% continuous AC output power boost on both back-up and on-grid output, enables more power generation and more yield.
6. 130% output power boost on back-up port at 60 seconds, allows big-power inductive loads connection on the back-up port.
7. Up to 15A maximum PV input current allows most higher current PV panels connection and lowers the system LCOE.
8. Support back-up port paralleling connection of up to 10 units to enable this inverter suitable in the commercial project.
9. Fast charging/discharging of up to 30A to meet the demand of higher consumption and energy trading.
10. Wide AC output power ranging from 3kW-8kW makes it suits most residential application scenarios globally.
11. Fast commissioning the inverter through App or OLED display.
12. Compatible with Sunways STE series batteries and batteries from industry-leading manufacturers such as PylonTech, Wattsonic, Dyness, etc.
All these leading features integrated in our hybrid inverters make our Sunways products with very high power grid adaptability and extraordinary performance.
With 28 years of German technology heritage and a sophisticated R&D team with an average of 10 years of PV industry experience, we offer high-quality hybrid inverters that allow you to use the solar energy generated intelligently. “With more and more different types of energies and power loads connected to the grid, the grid is confronting with more and more challenges on safety, stability, and reliability. As the brain of a PV system, hybrid inverter connects PV arrays, batteries, power loads, meter and utility grid, and controls the energy flows, which can optimize system operation and solve the instability problems PV generation and improve energy independence of rate to 100%. It will play an important role in the future distributed energy market.” Said Mr. Kui Li.
Sunways hybrid inverters rely on overloading ability and wide power range, the costs of some big power inverters are slightly lower than the similar products of other German brands. With many regional certificates received or on the way, this series is ready to sell in many markets such as Europe, the UK, South Africa, Australia, North America, India, etc.
