Solis S6 Pro 6kW Advanced Hybrid Inverter overview

The Solis S6 Pro 6kW Advanced Hybrid Inverter forms part of Solis’ PRO-series low-voltage energy storage range, engineered to handle demanding power requirements, high starting currents and flexible system expansion. This inverter integrates solar charging, battery management, generator connectivity and AC power conversion into a single robust unit.

Designed around a 48 V battery platform, the inverter delivers clean pure sine wave output, making it suitable for sensitive electronics, motor loads and high-demand household or business environments.

How the Solis S6 Pro 6kW hybrid inverter works

The Solis S6 Pro 6kW hybrid inverter intelligently manages power from multiple energy sources:

• Solar PV during daylight hours

• Battery storage for energy shifting and backup

• Grid or generator input for extended backup operation

Solar energy is prioritised to supply loads and charge batteries. When solar is unavailable, the inverter automatically draws from batteries or grid/generator sources to maintain uninterrupted power.

Solar charging and MPPT performance

This inverter features dual MPPT trackers, allowing independent optimisation of two solar strings. The wide MPPT voltage range ensures maximum solar energy harvest across varying irradiance conditions and flexible array layouts.

Dual MPPT capability makes the inverter ideal for roofs with multiple orientations or shading differences.

Battery compatibility and energy storage control

The Solis S6 Pro 6kW supports both lithium-ion and lead-acid batteries within a 40–60 V battery voltage range. Intelligent charge and discharge management protects batteries from over-charging, deep discharge and abnormal operating conditions.

With up to 135 A charge and discharge current, the inverter can support demanding loads and rapid energy transfer.

Backup power, surge capability and generator support

This inverter is designed for challenging backup power scenarios and offers:

• 200 % surge power for up to 10 seconds, suitable for pumps, compressors and motors

• Automatic UPS-level switching with transfer times under 4 ms

• Generator connectivity with multiple input methods and automatic generator control

These features make it well suited for load-shedding, rural installations and sites requiring dependable backup power.

Parallel operation and system expansion

The Solis S6 Pro 6kW hybrid inverter supports parallel operation and can be combined in single-phase or three-phase configurations, with system expansion up to 36 kW. This allows the system to scale as energy demands increase.

Typical applications

The Solis S6 Pro 6kW Advanced Hybrid Inverter is suitable for:

• Residential homes with high starting loads

• Backup power systems for load-shedding

• Small commercial and office installations

• Hybrid solar systems with generator support

• Installations requiring high surge performance
