Description
Introducing the Solis S6-EH3P20K-H—a 20 kW high-voltage three-phase hybrid inverter, specifically designed for large households and commercial properties seeking complete energy independence. It’s also a good solution for the “Green Tariff” government program. This inverter is the real deal command center your solar power plant, which ensures an uninterrupted and efficient power supply, even under the most challenging conditions.
Key advantages and innovative features of the Solis S6-EH3P20K-H 20-kilowatt model:
-
Exceptional flexibility in the placement of solar panels: This inverter is equipped with 4 MPPT trackers, each of which supports up to 1 input (string). This makes it the ideal solution for large rooftop systems with panels oriented in different directions and a complex structure. Solar panels can be arranged in 4 different planes. The MPPT tracker's voltage range is from 200 to 850 V , and the maximum input current 20A (30A short-circuit current), which ensures maximum use of solar energy.
-
Exceptional performance and stability: Say goodbye to outages! The device supports Overload up to 160% on the side of the photomodules for maximum power generation. It ensures unbalanced three-phase power supply a load that allows you to obtain to 40% phase overload. The time required to switch to the backup power supply is less than 10 milliseconds, which makes the transition seamless. In addition, it can withstand 10-second overvoltage to 160% backup power supply.
-
Smart Energy Management and Energy Savings: The inverter is equipped with AI that intelligently manages charging and discharging processes batteries based on multi-zone (Time-of-Use) rates. It integrates seamlessly with platforms VPP (Virtual Power Plant) and EMS (Energy Management System) and features built-in control for heat pumps with SG functionality, allowing you to optimize costs and manage energy efficiently.
-
System flexibility and scalability: The Solis S6-EH3P20K-H is compatible with widely used brands of high-voltage lithium iron phosphate rechargeable batteries, such as Pylontech with a voltage range 120–800 V. Thanks to the ability to scaling, you can easily expand your system's capacity in the future. The battery's rated charging current is 50 amps.
-
Reliable performance under any conditions: Thanks to the high IP66 protection rating, the inverter is reliably protected against dust and powerful water jets, allowing it to be installed outdoors. It operates flawlessly over a wide temperature range from-25°C to +60°C and features intelligent fan cooling. Its maximum efficiency reaches 97.7%, ensuring minimal energy loss.
-
It works with three-phase fuel-powered generators.
-
Easy configuration and monitoring: The device is equipped with 7-inch LCD screen for intuitive control and supports Bluetooth Apps for quick setup. A variety of connectivity options, such as CAN, RS-485, Ethernet, as well as optional Wi-Fi, cellular, and LAN modules, will allow you to stay up to date on the operation of your solar power plant.
Solis S6-EH3P20K-H — is a powerful, intelligent, and reliable three-phase inverter weighing 35.2 kg and dimensions 563 x 546 x 250 mm. This is the perfect solution to help you easily meet the energy needs of your large home or small commercial property with zero carbon emissions.
