Description
xSolis 50kW Hybrid Solar Inverter High Voltage 3 Phase S6-EH3P50K-H
The Solis S6-EH3P50K-H is a powerful three-phase high voltage hybrid solar inverter designed for demanding commercial and industrial energy storage systems. Built for the European market at 400VAC and 50Hz, this advanced 50kW inverter supports both on-grid and off-grid operation, helping businesses maximise solar self-consumption, integrate battery storage, and maintain reliable backup power for critical loads.
With 4 MPPTs, support for up to 2x rated PV input, and compatibility with high-power solar modules, the S6-EH3P50K-H is engineered for large rooftop and commercial PV systems. It also supports DC and AC coupling, making it ideal for new installations, retrofits, and system expansion projects.
High Voltage Battery Compatibility
This inverter is designed for high voltage lithium battery systems and is not suitable for ordinary 48V battery banks. It works with the new generation of modular lithium battery solutions, where multiple battery modules are connected in series to build a system voltage of up to 800V DC.
In commercial energy storage, high voltage battery architecture has become the preferred standard because it improves overall system efficiency and helps reduce the physical size of the battery installation. By operating at a much higher DC voltage, the system draws lower current for the same power output. This allows the use of smaller cables, slimmer busbars, reduced heat losses, and easier thermal management. As a result, the complete lithium-ion battery system can be more compact, cleaner in design, and easier to cool, even with fan-assisted air cooling. A full list of compatible batteries is provided below.
