xSolis 10kW Three Phase Hybrid Solar Inverter High Voltage S6-EH3P10K2-H
The Solis S6-EH3P10K2-H is a powerful 10kW three phase high voltage hybrid solar inverter designed for advanced solar PV and battery storage installations. It connects solar panels, the grid and a compatible high voltage lithium battery system, allowing solar energy to be used during the day, stored in the battery and released when required.
This inverter is ideal for customers who want to reduce grid consumption, improve energy independence and build a reliable three phase solar battery storage system for residential, agricultural or light commercial applications.
High Solar Input for Maximum Energy Harvesting
The 10kW model supports a recommended maximum PV array size of up to 20kW, with a maximum usable PV input power of 16kW. This gives the system excellent solar harvesting potential and allows the inverter to make better use of available roof space or ground-mounted solar arrays.
With a maximum PV input voltage of 1000V, a rated PV voltage of 600V and a wide MPPT operating range from 200V to 850V, the inverter offers flexible solar string design for professional installers. The dual MPPT design provides 2 independent MPPT trackers with 2 PV string inputs, helping improve performance when panels are installed across different roof orientations.
Designed for High Voltage Battery Storage
The Solis S6-EH3P10K2-H is designed for high voltage lithium battery systems, with a battery voltage range from 120V to 600V. It delivers up to 10kW battery charge and discharge power, making it suitable for installations where strong battery performance is required.
The inverter also supports a maximum battery charge and discharge current of 50A and communicates with compatible lithium batteries through CAN and RS485. This allows safe, intelligent battery management and helps protect the battery during daily charge and discharge cycles.
Reliable Three Phase AC Output
The 10kW Solis high voltage hybrid inverter provides a rated AC output power of 10kW and a maximum apparent output power of 10kVA. It is designed for 3/N/PE, 380V / 400V three phase systems and supports both 50Hz and 60Hz grid frequency.
With a rated grid output current of 15.2A / 14.4A, a power factor of more than 0.99 and low current distortion of less than 3% THDi, the inverter is engineered for efficient and stable grid-connected operation.
Fast Backup and Off-Grid Support
The S6-EH3P10K2-H supports seamless on-grid and off-grid switching in less than 10ms, helping maintain power to essential loads during grid interruptions. This makes it suitable for properties that require a dependable backup power function alongside normal solar self-consumption.
In off-grid mode, the inverter can support up to 160% overload for 60 seconds, giving it the strength required to start demanding loads such as motors, water pumps, compressors and air conditioning units.
Flexible System Expansion
For larger energy storage projects, the inverter supports up to 6 units in parallel. This allows the system to be expanded when greater power capacity is needed, making it suitable for larger homes, farms, workshops and commercial energy storage applications.
The inverter also supports three phase unbalanced output, with each phase able to support up to 50% of the rated inverter power. This is particularly useful in real installations where electrical loads are not always evenly distributed across all three phases.
Generator and Existing PV Support
The Solis S6-EH3P10K2-H supports grid side generator access, making it suitable for sites where the grid supply is limited, unstable or unavailable for part of the time. It can also support existing PV grid-tie power connection for export control and off-grid use, helping upgrade existing solar systems into more advanced battery storage solutions.
Smart Monitoring with SolisCloud
SolisCloud gives users and installers smart remote monitoring, system control, AI optimisation and instant troubleshooting from one platform. This makes it easier to check system performance, monitor energy flow and identify issues quickly.
