ESI 6K-S1 1F Sofar Hybrid Inverter

The Sofar ESI S1 series hybrid inverter is a unit that, together with the Sofar BTS 5K battery pack, creates a modern, safe and highly efficient PowerAll electricity storage system.

All-in-one residential energy storage system with integrated hybrid inverter

SofarSolar's high-voltage battery system consists of 1 to 6 BTS 5K battery modules, and a 1-phase ESI 3…6K-S1 hybrid inverter. Up to six units can be connected in parallel, enabling a configuration of up to 36 kW and 180 kWh.

Smart Energy Management

The battery modules come with an integrated battery management system and power control unit. The SOFAR PowerALL can intelligently adjust the output voltage and current of the battery according to the battery's SOC. This leads to an increase in the available energy capacity.

Modular

The battery capacity can easily be expanded through the system's modular, stackable design. In combination with click-to-connect cables, installation is both fast and user-friendly.

Safety

The LiFePO4 battery modules come with CATL battery cells. In addition, there are multiple active and passive protection functions, provided by the BMS, power control unit and inverter. On the battery side fuses are installed.

Features:

• Single-phase
• Number of MPP trackers: 2
• Built-in battery pack balance management unit, increases battery capacity
• Max. photovoltaic current input: 16 A, suitable for high-current/bifacial modules
• Stacked and integrated design, convenient installation and simple maintenance
• The battery side is completely electrically isolated, making the system safer
