Solis 12kW Single-Phase Hybrid Inverter with Screen

Solis 12kW Single-Phase Low-Voltage Hybrid Inverter with Screen

The Solis 12kW Single-Phase Low-Voltage Hybrid Inverter is a powerful solar energy management solution designed for larger residential properties, farms, guesthouses, offices and small businesses. It combines solar panel input, low-voltage battery storage, grid electricity and generator support in one advanced hybrid inverter.

The Solis S6-EH1P12K03-NV-YD-L provides a rated output power of 12000W and supports suitable lithium-ion and lead-acid battery systems operating between 40V and 60V. With a recommended maximum solar panel array size of up to 24000W, this inverter is suitable for customers who require stronger solar generation, battery charging and backup power performance.

Main Benefit

The main benefit of the Solis 12kW Single-Phase Hybrid Inverter is its ability to manage solar panels, battery storage, grid electricity and generator input intelligently. The inverter can prioritise solar energy, charge a connected battery bank and provide backup power during load shedding or unexpected grid interruptions.

Its high power output, substantial solar input capacity and low-voltage battery compatibility make it suitable for properties with higher electricity requirements that still require flexible and scalable energy storage.

Hybrid Inverter Technology

The Solis 12kW Hybrid Inverter supports on-grid, off-grid and generator-assisted operating modes. During normal operation, solar power can be used to supply connected appliances, charge the battery bank and reduce grid electricity usage.

During grid failures, the inverter can switch to backup power in less than 10ms. This helps maintain electricity supply to suitable essential appliances with minimal interruption.

The inverter also supports solar-only off-grid operation where the system design permits it. This can reduce initial installation costs for customers who want to begin using solar power before adding battery storage. A suitable battery bank remains recommended for dependable backup power after sunset or during reduced solar production.

Solar Panel Compatibility

The Solis 12kW Hybrid Inverter supports a recommended maximum solar panel array size of up to 24000W and a maximum usable PV input power of up to 19200W. This allows customers to install a substantial solar array for improved daytime electricity generation and battery charging.

The inverter includes 3 independent MPPT trackers with support for up to 6 solar panel strings. Its MPPT voltage range is 80V to 520V, while the maximum PV input voltage is 550V. The solar start-up voltage is 100V.

The inverter supports a maximum PV input current of 40A per MPPT tracker and a maximum short-circuit current of 50A per MPPT tracker. Correct solar panel string sizing remains essential to ensure safe operation within the inverter voltage and current limits.

Battery Compatibility

The Solis 12kW Low-Voltage Hybrid Inverter supports suitable lithium-ion and lead-acid batteries operating between 40V and 60V. Communication with compatible battery systems is supported through CAN and RS485 interfaces.

The inverter supports a maximum battery charging and discharging current of up to 250A. A correctly sized battery bank is important for an inverter of this capacity, particularly when larger electrical loads must operate during load shedding or extended grid interruptions.

Generator Compatibility

The Solis 12kW Hybrid Inverter supports multiple generator connection methods and automatic generator control. A compatible generator can assist with supplying power and charging the battery bank during prolonged outages, poor weather or periods of high electricity usage.

Generator integration is useful for farms, lodges, remote properties and businesses that require reliable backup power when solar energy and battery storage alone may not be sufficient.

Smart Load Management

The Solis 12kW Hybrid Inverter supports smart load management to help extend battery backup time for critical appliances. This allows customers to prioritise important circuits while managing less essential loads separately.

Critical loads may include lighting, internet equipment, security systems, refrigeration, office equipment and selected household appliances. High-consumption appliances should be assessed carefully during solar system planning.

Existing Grid-Tied Solar System Integration

The Solis 12kW Hybrid Inverter supports connection with compatible existing grid-tied solar systems for export control and off-grid use. This provides a practical upgrade path for customers who already have solar panels and want to add battery storage and backup power capability.

Existing system integration requires professional planning to ensure that the inverter, solar array, battery bank and electrical protection equipment operate correctly together.

Parallel Expansion

The Solis 12kW Hybrid Inverter supports parallel operation with up to 6 compatible inverter units. This allows customers to expand the total system capacity when additional power is required.

Parallel inverter installations require professional system design, suitable battery storage, correctly sized cabling, electrical protection and proper commissioning.

Screen, Monitoring and Communication

The Solis 12kW Hybrid Inverter includes a large 7-inch industrial-grade touchscreen for convenient local monitoring and configuration. Bluetooth and app connectivity provide additional control and access to inverter information.

The inverter supports SolisCloud remote monitoring for smart control, performance visibility, troubleshooting and system optimisation. RS485 communication is included, while optional cellular, WiFi and LAN monitoring accessories are available.

Performance

The Solis 12kW Hybrid Inverter provides a maximum efficiency of up to 97.6% and an EU efficiency of up to 97.0%. Battery charging efficiency from solar panels exceeds 94.9%, while battery charging and discharging efficiency through AC power exceeds 94.33% and 93.51% respectively.

In off-grid mode, the inverter supports up to twice its rated output power for 10 seconds. This helps accommodate the temporary start-up requirements of motors, water pumps, air conditioners and other suitable appliances.
