Solis S6-EH1P10K-L-PLUS – 10 kW Hybrid Solar Inverter for Professional PV Systems
The Solis S6-EH1P10K-L-PLUS is a 10 kW single-phase low-voltage hybrid solar inverter developed for professional residential PV, solar battery and backup power installations. It combines high-current PV inputs, 40–60 V battery integration, a full 10 kW backup output and intelligent energy management in one scalable platform.
Designed for European solar installers, EPC companies and resellers, the inverter is suitable for new solar PV systems, battery retrofit projects and complete solar energy storage kits where high single-phase output, flexible system design and dependable backup operation are required.
High PV capacity for modern solar panel installations
The Solis S6-EH1P10K-L-PLUS provides two independent MPPT trackers and four PV string inputs, allowing installers to separate different roof orientations, module groups or array sections within the same system.
The inverter supports a recommended maximum PV array size of 20 kW and up to 16 kW of usable PV input power. Its 90–435 V MPPT operating range, 90 V start-up voltage and 500 V maximum input voltage provide flexibility when designing residential and light commercial strings.
Each MPPT supports up to 42 A input current and 48 A short-circuit current, making the inverter suitable for current-generation, high-power solar panels with increased operating current. This is particularly relevant when specifying N-type, TOPCon or other high-current PV modules for new solar installations.
Low-voltage solar battery integration
The Solis S6-EH1P10K-L-PLUS is designed for 40–60 V low-voltage solar battery systems and supports both compatible lithium-ion and lead-acid batteries.
For the 10 kW model, maximum battery charging and discharging power is 10 kW, with up to 208 A battery current. CAN and RS485 communication interfaces support data exchange between the inverter and compatible battery management systems.
This makes the inverter a practical option for installers building complete solar battery systems where high charge and discharge performance is required without moving to a high-voltage battery architecture. Battery model compatibility should always be confirmed against the current Solis approved battery list before procurement or commissioning.
Full 10 kW single-phase grid output
On the grid side, the Solis S6-EH1P10K-L-PLUS delivers 10 kW rated active power and 10 kVA maximum apparent power on a single-phase L/N/PE connection.
It is designed for 220 V or 230 V grids and supports both 50 Hz and 60 Hz operation. Rated output current is 45.5 A at 220 V or 43.5 A at 230 V, while total harmonic current distortion remains below 3%.
The inverter therefore provides a high-output single-phase solution for projects where the available grid connection, local network approval and site design permit a 10 kW single-phase inverter.
Fast backup power for critical loads
The dedicated backup output is rated at the full 10 kW inverter capacity, allowing installers to supply a substantial protected-load circuit during a grid outage.
Backup switching takes less than 10 milliseconds, helping connected equipment continue operating with minimal interruption. The backup output can also provide up to twice the rated apparent power for 10 seconds, supporting short starting-current peaks from equipment such as pumps, compressors, refrigeration systems and selected motor loads.
A maximum AC passthrough current of 65 A gives installers additional flexibility when planning protected distribution boards and backup load circuits. Correct load assessment, phase balancing and protective-device selection remain essential during system design.
Integrated generator connection
The Solis S6-EH1P10K-L-PLUS includes a dedicated generator input supporting up to 10 kW input power and a maximum current of 45.5 A at 220 V or 43.5 A at 230 V.
This allows professional installers to incorporate a compatible generator into a multi-source backup system where solar generation, solar battery storage and grid power may not provide sufficient resilience on their own.
Generator integration can be particularly useful for rural properties, weak-grid locations and sites requiring longer backup autonomy during extended grid failures.
Intelligent charging and energy management
The inverter uses intelligent charging and discharging control based on Time-of-Use electricity tariffs, enabling stored energy to be managed around lower-cost charging periods and higher-cost consumption periods.
Integration with compatible virtual power plant and energy management platforms supports more advanced control strategies for self-consumption, tariff optimisation and coordinated energy use.
The system can also be expanded using parallel inverter connections and AC coupling, giving installers a route to increase capacity or integrate the inverter into more complex PV and energy storage configurations.
Installer-focused setup and communication
A large 7-inch LCD display provides direct access to system information and operating settings. Bluetooth and app support are included for fast local configuration during installation and commissioning.
Standard communication interfaces include RS485 and CAN, while Wi-Fi, GPRS and LAN connectivity are available as optional communication methods. These options support remote monitoring and allow the communication method to be selected according to the project location and network infrastructure.
High efficiency across PV and battery operation
The Solis S6-EH1P10K-L-PLUS achieves a maximum inverter efficiency of 96.2% and a European efficiency of 96.1%.
Maximum battery charging efficiency is specified at 95.3% from PV and 93.9% from AC. Maximum battery-to-AC discharge efficiency is 93.8%.
These figures allow professional installers and system designers to account for conversion losses more accurately when modelling annual production, battery cycling and expected self-consumption performance.
IP66 housing for demanding installation environments
The inverter is supplied in an IP66-rated enclosure and is designed to operate across an ambient temperature range of −40°C to +60°C.
Intelligent fan cooling manages operating temperature under higher loads, while the stated maximum installation altitude is 3,000 metres. The 10 kW model measures 335 × 560 × 253 mm and weighs approximately 24 kg.
These characteristics make the inverter suitable for a wide range of indoor and outdoor installation locations, provided the mounting position, ventilation clearances and environmental requirements in the installation manual are followed.
Integrated electrical protection
The Solis S6-EH1P10K-L-PLUS includes anti-islanding protection, ground-fault monitoring and DC reverse-polarity protection. Integrated AFCI 2.0 arc-fault protection is listed as an optional feature.
The inverter is designed according to multiple safety, EMC and grid-connection standards, including IEC/EN 62109-1/-2 and EN 61000-6-2/-3. Local grid-code acceptance and the exact certification required for the installation country should be checked before ordering.
Suitable applications
The Solis S6-EH1P10K-L-PLUS is well suited to:
- High-output residential solar PV installations
- New complete solar battery systems
- Low-voltage battery retrofit projects
- Whole-home or selected-load backup systems
- Solar installations with high-current PV modules
- Properties requiring generator-supported backup
- AC-coupled energy storage upgrades
- Scalable parallel inverter configurations
- Time-of-Use tariff optimisation projects
- Professional installer and EPC solar kits
Why specify the Solis S6-EH1P10K-L-PLUS?
For professional solar installers, the main value of the Solis S6-EH1P10K-L-PLUS is the combination of 10 kW single-phase output, high-current dual MPPT inputs, low-voltage battery compatibility and full-power backup operation.
It supports larger PV arrays, substantial battery charging and discharging power, generator integration and flexible communication options without requiring a high-voltage battery system. The inverter can therefore be used across new-build, retrofit and backup-focused projects while keeping system architecture familiar for installers already working with 48 V-class solar batteries.
For procurement teams and solar wholesalers, the model fills the demand for a high-capacity single-phase hybrid inverter that can be supplied as an individual component or included in a complete solar energy storage kit with compatible batteries, protection equipment, monitoring devices and installation accessories.
The Solis S6-EH1P10K-L-PLUS 10 kW hybrid solar inverter is a strong specification for installers who need high PV input capacity, flexible low-voltage solar battery integration and fast backup switching in one professional energy storage platform.
