Solis S6-EH3P8K-H-EU 8kW Three-Phase Hybrid Energy Storage Inverter

The Solis S6-EH3P8K-H-EU is a three-phase high-voltage hybrid energy storage inverter with 8 kW rated output power and 8 kVA apparent power. It features four MPPT inputs with a maximum PV input capacity of 160% to maximize solar energy utilization, and supports high-voltage lithium battery systems with a voltage range of 120–600 V (up to 700 V). The transformerless design includes integrated backup functionality with less than 10 ms switch time, natural cooling for silent operation, and fanless construction to extend lifespan.

The inverter integrates smart energy management with AI-based time-of-use (TOU) tariff optimization, seamless VPP and EMS platform integration, and three-phase unbalanced output support allowing up to 50% of rated power per phase. Communication options include CAN, RS485, with optional Wi-Fi, Cellular, and LAN connectivity. The unit carries IP66 ingress protection and operates from −25 to +60 °C, achieving maximum efficiency of 97.90% (EU efficiency 97.51%).

Designed for European grid connection standards (G98/G99, VDE-AR-N 4105, EN 50549-1, and others), the S6-EH3P8K-H-EU includes an integrated DC switch, reverse-polarity protection, and optional integrated AFCI 2.0. The package includes an energy meter and three current transformers (CTs) for monitoring.
