Solis S6 Pro 6kW Advanced Hybrid Inverter

The Solis S6 Pro 6kW Advanced Hybrid Inverter (SOL-S6-EH1P6K-L-PRO) is a high-performance low-voltage hybrid inverter designed for modern solar power, battery storage and backup applications. It combines solar PV generation, battery storage, grid power and generator support in one intelligent energy management system.

With a 6kW rated inverter output and up to 9.6kW maximum PV input, the Solis S6 Pro 6kW is well suited to residential solar installations and other applications where reliable backup power and efficient energy management are important.

The S6 Pro range is designed for demanding power scenarios and includes advanced backup capabilities, generator connectivity, intelligent energy management and flexible system expansion.

Why Choose the Solis S6 Pro 6kW Hybrid Inverter?

South African households and businesses increasingly use solar and battery storage to reduce dependence on grid electricity and maintain power during outages. The Solis S6 Pro 6kW Advanced Hybrid Inverter is designed to manage these different energy sources intelligently.

Key advantages

Powerful Solar Input for a Flexible Hybrid System

The Solis S6 Pro 6kW supports a maximum PV input of up to 9,600W and uses dual MPPT technology. This gives installers greater flexibility when designing solar arrays with different roof orientations or panel configurations.

The high PV input capability also allows the inverter to be paired with a suitably sized solar array to maximise daytime solar generation and provide energy for household consumption and battery charging.

For the exact PV voltage, current, string configuration and panel compatibility, always follow the latest Solis installation documentation and applicable electrical requirements.

Advanced Battery Storage Management

The S6 Pro 6kW is designed around low-voltage battery storage and supports high battery charge and discharge currents of up to 135A.

This makes the inverter suitable for battery-based solar systems where homeowners want to store excess solar energy during the day and use stored energy when solar production is low or the grid is unavailable.

The inverter also provides multiple configurable charging and discharging time periods, allowing the system to be configured around different energy-use requirements.

Reliable Backup Power During Load Shedding

One of the major advantages of a hybrid inverter is its ability to provide backup power when grid electricity is unavailable.

The Solis S6 Pro 6kW provides automatic UPS switching and is designed to handle demanding backup loads. Its 200% backup overload capability for up to 10 seconds can provide additional short-duration power for suitable loads with higher starting or surge requirements.

This makes the S6 Pro particularly attractive for South African solar installations where backup power is an important consideration.

Important: The actual appliances that can be powered during an outage depend on the inverter configuration, battery capacity, backup circuit, installation design and appliance starting loads.

Generator Integration

The Solis S6 Pro 6kW Advanced Hybrid Inverter supports generator connectivity and automatic generator On/Off control.

This provides another layer of energy resilience for installations where extended backup operation is required. A suitably configured generator can supplement the solar and battery system when necessary.

Generator integration should be designed and installed by a qualified professional according to the inverter manufacturer's requirements and applicable South African electrical regulations.

Intelligent Energy Management

The Solis S6 Pro is more than a conventional solar inverter. It is designed to coordinate solar generation, battery storage, grid electricity and generator power.

Its energy-management features can help users optimise when energy is generated, stored and consumed. Peak shaving functionality can also assist suitable installations in managing higher periods of electricity demand.

Monitoring and communication options allow system performance and energy information to be monitored through compatible Solis monitoring equipment and platforms.

Expandable System Capability

For larger applications, the S6 Pro platform supports parallel operation. Up to six compatible units can be configured to provide up to 36kW of backup capacity, subject to the correct system design and installation requirements.

This provides a potential upgrade path for installations where energy requirements increase over time.
