Products Description
what are features of Solis S6 3-6K Hybrid Inverter?

The Solis S6 3-6K Hybrid Inverter establishes a new standard for scalability through its Plug-and-Play Modular Architecture. Instead of being a rigid inverter, the system allows you to easily expand from 3kW to 6kW (and in parallel, even larger) by simply adding more compatible battery modules or solar strings. For example, you can build a basic 3kW system to power essential loads and later add a 3kW battery bank, for instance, to allow an EV charger or backup suite to plug into the system without the need to rewire or create downtime. Even the Dual-Port Battery Interface is intended for hybrid lithium-ion/lead-acid configurations, allowing you to upgrade your batteries over time as needed.
Carbon Offset Tracker: Displays live emissions avoided, and can generate exportable reports for ESG reporting.
Battery "Health Scorecard": Degradation assessments, and a full cost-benefit analysis for determining when to purchase a replacement unit.
Scenario Simulator: Analyzer for conducting "what-ifs" for scenarios like adding a solar panel(s) to existing units, or upgrades to a flow battery to increase personal ROI.


The Solis S6 3-6K Hybrid Inverter's Battery Ecosystem Orchestrator™ goes above and beyond simple charge management.
Cross-Battery Optimization: This technique maximizes efficiency across various battery types by pushing high-frequency cycles to lithium cells while maintaining lead-acid batteries available for steady-state loads when set up for mixed battery types (Tesla Powerwall + older lead-acid batteries).
One of the essential features is Reverse Power Flow Prevention: The inverter uses advanced circuiting to detect loss of battery charge, such as from a malfunctioning appliance, and isolates the compromised appliance without causing downstream damage across the other connected devices. This function is essential for multi-battery systems from a safety perspective.
The Peer-to-Peer Energy Portal inverters allow residential systems to take on the role of trading personal energy:
Microgrid Federation: Connecting to neighbors creates a neighborhood energy pool. One household's excess solar can offset another's electric vehicle charging or peak times.
Dynamic Tariff Arbitrage: Connected to smart meters, power can be exported for additional revenue to balance the electric grid, taking advantage of higher time-of-use pricing when grid congestion, like a post-sunset demand spike. This feature produced significantly decreased household energy costs averaging 28%, and overall demand was alleviated during the peak summer times in a pilot project in South Australia.
