Use more rooftop solar
Surplus photovoltaic energy is stored for evening and nighttime consumption, increasing self-consumption and reducing electricity purchased from the grid.
Residential battery energy storage system
ENERSTO 64 brings intelligent COMEXIO energy management to villas, multi-family homes and residential communities. The system coordinates rooftop solar, household consumption, heat pumps and EV charging while reserving energy for selected backup circuits when required by the project design.

Technical specifications
The overview uses the currently confirmed ENERSTO 64 product information. The complete product data sheet is in preparation; final system design is confirmed from the household load profile, photovoltaic system and required operating strategy.
Modular capacity concept
A standardized 16 kWh battery module is the building block of the ENERSTO platform. Capacity can be matched to the current load profile and increased later within the approved system range.

Capacity path for ENERSTO 64
ENERSTO 64 starts with two standardized 16 kWh slide-in battery modules for 32 kWh of storage capacity. A third or fourth module can be added in defined 16 kWh steps, allowing the residential system to expand to 48 kWh or 64 kWh as household demand, photovoltaic generation, heat-pump operation or EV charging requirements increase.
Each expansion is technically assessed and commissioned for the existing system, available cabinet capacity and intended operating strategy.
System value
Surplus photovoltaic energy is stored for evening and nighttime consumption, increasing self-consumption and reducing electricity purchased from the grid.
Intelligent control coordinates the battery with household demand, heat pumps and EV charging to use available energy more effectively.
A project-specific backup strategy can keep capacity available for selected residential circuits when backup operation is included in the electrical design.
Applications
Frequently asked questions
ENERSTO 64 is designed for residential applications that combine rooftop photovoltaic generation with household loads, heat pumps, EV charging and selected backup requirements.
The base configuration uses two standardized 16 kWh battery modules for 32 kWh. One or two additional modules can be integrated to provide 48 kWh or the full 64 kWh capacity.
The complete ENERSTO 64 product data sheet is currently in preparation. Project-specific technical information can be provided during system planning.
