Solis 6KW Hybrid Pro Solar Inverter
Model: S6-EH1P-6-K-L-Pro
The Solis S6-EH1P6K-L-PRO is a 6kW single-phase low voltage hybrid solar inverter designed for residential and light commercial solar energy storage systems. Featuring dual MPPT inputs, automatic UPS switching with less than 4ms transfer time, and generator connectivity with automatic On/Off control, this inverter delivers reliable performance under Pakistan's challenging grid conditions. Built with IP66 weatherproof protection, high-frequency battery isolation topology, and support for both lithium-ion and lead-acid batteries, the Solis 6KW Hybrid Pro is engineered for maximum system flexibility and long-term energy independence.
Key Features
- 6kW Rated Output with 200% Surge Capability: Handles heavy loads and motor startups with 10-second 200% surge power backup overload support.
- Automatic UPS Switching (<4ms): Near-instantaneous switchover ensures sensitive equipment stays protected during grid outages.
- Generator Connectivity: Multiple input methods with automatic generator On/Off control for seamless backup power integration.
- Dual MPPT Inputs: Two independent MPPT channels (90–520V range) maximize solar harvest from different panel orientations or partial shading conditions.
- Up to 135A Max Charge/Discharge Current: Supports fast battery charging and high discharge rates for demanding load scenarios.
- IP66 Weatherproof Rating: Fully protected against dust and water jets — suitable for outdoor wall mounting in Pakistan's climate.
- 6 Customisable Charge/Discharge Time Settings: Flexible scheduling for peak shaving in both self-use and generator modes.
- Compatible with Lithium & Lead-Acid Batteries: Works with a wide range of battery types including Pylontech, and other major brands.
- Parallel Operation Support: Up to 36kW in 1-phase or 3-phase flexible parallel connection for larger system requirements.
