Sunverge Solar Integration System

The Sunverge Solar Integration System (SIS) is an intelligent distributed energy storage system that captures solar power and delivers it when needed most. It combines batteries, power electronics, and multiple energy inputs in a UL-certified appliance controlled by software running in the cloud. The SIS is a utility-grade product designed for the consumer market.

Sunverge SIS at the Site

SIS units are installed at homes and businesses, integrating with new or existing solar systems, and connect to the grid and the local electricity supply. Each unit runs applications to automatically lower electricity bills, improve reliability, and protect the grid.

Sunverge SIS at the Site

The unit monitors solar generation, electricity demand, utility price signals, and battery capacity in real-time, prioritizing operations in response to what is happening at the site and on the grid. As conditions change over time, the unit adapts. The SIS functions automatically without the need for active involvement or behavioral change from energy consumers.


If the site is generating more solar power than it needs, the excess is stored for future use.


When the grid goes down, the unit provides solar backup power to the site.


When electricity prices are high, the unit dispatches both solar and stored power to reduce consumption.


As energy consumption patterns change, the unit adapts to serve the demand and “shape” the load.

Sunverge SIS on the Grid


As units are deployed at customer sites, a virtual power plant of solar and storage resources is built. Aggregated power and energy is reserved, scheduled, and dispatched across the fleet of units. On top of this distributed platform the virtual power plant provides services tailored to the needs of the grid.

Sunverge SIS on the Grid


The virtual power plant operates both automatically and on-demand. Units respond to load patterns across circuits and feeders, shaping the load to localized needs. Voltage and frequency are kept in optimum ranges with units injecting and absorbing real and reactive power based on the real-time state of the distribution network.

Sunverge SIS on the Grid


As events occur on the grid, units are orchestrated to provide a flexible response. Integration with utility systems allows for more automated and data-driven control. As for the consumer at the site, the virtual power plant prioritizes its operations to adapt to changing conditions on the grid in real-time, and changing needs for the utility over time.
