Technological Benefits

Integrated 4 MPPTs and String Current up to 20A:

  • Optimizes energy harvest by efficiently tracking maximum power points from multiple solar panels, up to700W PV modules. With the increased module capability, the capacity can be increased and requiring less module space, increasing overall system performance and output.

Up to 140A/70+70 Max Charge/Discharge Current:

  • With third-generation SiC technology, the charge and discharge capacity is 60% higher than that of traditional solutions, enables rapid charging and discharging of batteries, ensuring quick response to fluctuating energy demands and maximizing energy storage efficiency.

Supports 200% DC:AC Ratio:

  • With the maximum DC ratio up to 200%. By introducing the energy storage system, the photovoltaic energy exceeding the inverter’s rated output power can be stored in the battery instead of being wasted, thereby maximizing the use of PV energy, making PV power meet all-weather demand, enhances system scalability, and maximizes utilization of PV module power and efficiency.

Dual Battery Interface:

  • Facilitates flexible system expansion and customization, accommodating different battery types and configurations to meet specific energy storage needs. The system allows the use of two BMS signals and capable of controlling the two charge ports independently.

Compatibility with Multiple Brands of Battery Models:

  • Provides customers with a wide range of battery options, allowing them to choose the most suitable and cost-effective solution for their energy storage requirements.

Peak Shaving Control in Both Grid and Generator Conditions:

  • Optimizes energy usage by reducing peak demand, resulting in lower electricity costs and increased grid stability, particularly during high-demand periods.

Max. 6 Parallel Operation for On-Grid and Off-Grid:

  • Support 6 products running in parallel to form a energy storage system of up to 300kW, allowing for greater flexibility and resilience in both grid-connected and off-grid scenarios.

Solis remains committed to driving solar innovation and ushering in a transformative era of sustainable and resilient power management for businesses globally. For more information about the S6-EH3P(29.9-50)K-H and other products, please visit
