Solis S6 Pro 5kW Advanced Hybrid Inverter overview

The Solis S6 Pro 5kW Advanced Hybrid Inverter is part of Solis’ PRO-series low-voltage energy storage range, designed for installations that require high surge power, flexible system expansion, and advanced energy control. This inverter integrates solar charging, battery management, generator input, and AC power conversion into a single robust unit.

Built around a 48V low-voltage battery platform, the Solis S6 Pro 5kW inverter delivers clean pure sine wave output, making it suitable for sensitive electronics, motor loads, and demanding household or business environments.

How the Solis S6 Pro 5kW hybrid inverter works

The Solis S6 Pro 5kW hybrid inverter intelligently manages energy from multiple sources:

• Solar PV for daily energy generation

• Battery storage for energy shifting and backup

• Grid or generator input for extended backup operation

Solar energy is prioritised for loads and battery charging. 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 MPPT system continuously tracks the optimal operating point of the PV array to maximise solar energy harvest under varying irradiance conditions.

The wide MPPT voltage range enables flexible solar array design and improved efficiency across different installation scenarios.

Battery compatibility and energy storage control

The Solis S6 Pro 5kW Advanced Hybrid Inverter supports both lithium-ion and lead-acid batteries. Intelligent charge and discharge management protects batteries against over-charging, deep discharge, and abnormal operating conditions.

High charge and discharge current capability allows the inverter to handle demanding loads while maintaining stable battery performance.

Backup power, surge capability and generator support

This inverter is designed for demanding backup power scenarios. It offers:

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

• Automatic UPS-level switching with fast transfer times

• Generator connectivity with automatic generator start/stop functionality

These features make the Solis S6 Pro 5kW inverter well suited for load-shedding, rural installations, and sites requiring reliable backup power.

Parallel operation and system expansion

The Solis S6 Pro 5kW hybrid inverter supports parallel operation and can be combined with additional units to scale system capacity. Flexible single-phase and three-phase configurations allow system expansion up to higher power levels, making this inverter suitable for growing energy demands.

Typical applications

The Solis S6 Pro 5kW 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
