Solis S6-EH3P6K-H-EU Hybrid Inverter | 6kW | 3-phase | HV

At energoshop.eu, we know how important efficient energy management is for your home. That’s why we present the Solis S6-EH3P6K-H-EU – a modern, three-phase high-voltage hybrid inverter. This advanced inverter is designed to maximize your energy independence by intelligently directing the generated PV energy first to power household appliances, then to charge the connected battery, with any surplus exported to the grid. At night or during periods of low sunlight, the inverter seamlessly switches to the stored battery power, ensuring uninterrupted supply.

The heart of the Solis S6-EH3P6K-H-EU is its intelligent energy management, which integrates smoothly with VPP (Virtual Power Plant) and EMS (Energy Management System) platforms. With AI technology, the inverter optimizes the battery charging and discharging process based on Time-of-Use (TOU) tariffs, enabling smart cost savings on energy. You don’t have to worry about power outages – the switchover time between grid and battery supply is under 10 milliseconds, ensuring virtually unnoticeable continuity of power for your home. What’s more, the inverter supports an impressive 160% PV input capacity, efficiently utilizing even the highest solar production. This model provides a nominal output power of 6 kW for both grid and backup ports, with a peak apparent output power of up to 9.6 kVA for 60 seconds in backup mode. It also supports three-phase unbalanced output, supplying up to 50% of nominal power per phase. With a PV efficiency of 97.00% and a European efficiency of 97.10%, the Solis S6-EH3P6K-H-EU ensures excellent energy conversion. And with an MPPT efficiency of 99.90%, you can be sure every ray of sunlight is maximized.

This inverter also offers significant flexibility and scalability. It is compatible with many popular lithium batteries with a voltage range from 120 to 600 Vdc, and in some cases up to 700 Vdc if specified on the device label and packaging. The system can be easily expanded thanks to parallel connection and AC coupling capability, supporting up to six inverters operating in parallel.

System configuration and monitoring are extremely intuitive thanks to the SolisCloud mobile app with built-in Bluetooth module. You can remotely monitor your system using optional Solis data loggers that connect via the USB COM port and transmit data to the SolisCloud platform via WiFi, LAN, or 4G. What’s more, the factory pre-wiring for batteries, meters, and the CAN bus significantly shortens installation time, which every installer will appreciate.

The Solis S6-EH3P6K-H-EU offers four versatile operating modes that you can tailor to your needs:

• Self-Use Mode: Prioritizes on-site PV energy consumption, stores surplus, and then exports it to the grid.
• Feed-in Priority Mode: After supplying household loads, the inverter exports PV surplus to the grid.
• Off-Grid Mode: Ideal for systems without a grid connection, limiting PV production when the battery is full and loads are low.
• Peak Shaving Mode: Allows you to set a maximum grid power draw (Pmax) with automatic supplementation from the battery, optimizing energy costs.

Additionally, the Time of Use Switch function enables precise scheduling of battery charging and discharging. The “Allow Grid Charging” option allows the battery to be charged from the grid under specific conditions, e.g., when the charge level drops below a set minimum or there is no PV power during the Time-of-Use window.

In terms of design and safety, the inverter is transformerless. It weighs 27.58 kg and has compact dimensions of 600 × 500 × 210 mm. It features low night-time self-consumption (below 25 W) and convection cooling, resulting in low noise emissions below 46.9 dB(A). With an IP66 protection rating, it is resistant to dust and powerful water jets, allowing installation in a wide operating temperature range from -25°C to +60°C, even at altitudes up to 4000 m above sea level. Integrated protections include anti-islanding, output overcurrent and short-circuit protection, built-in DC switch, reverse DC polarity protection, PV surge protection, and battery polarity protection. An optional integrated AFCI 2.0 (Arc Fault Circuit Interrupter) is also available. The manufacturer declares compliance with Directive 2014/53/EU. The inverter packaging includes all necessary accessories, such as a mounting plate, screws, dust cover, current transformers (CTs), an Eastron meter, and communication cables, making installation quick and efficient.

By choosing the Solis S6-EH3P6K-H-EU, you are investing in the future of your home – gaining reliable, safe, and intelligent energy management that will truly reduce your bills and increase your comfort of living.
