Sunverge Introduces Next-Generation Energy Storage System


Sunverge Energy, a provider of intelligent energy storage and distributed energy resource management, has introduced the next generation of its Solar Integration System (SIS), now offering a package of more battery options and a streamlined design with enhanced system intelligence.

“These changes are based on feedback from utility customers and solar power providers around the globe who requested more battery and hardware solutions to meet the diverse needs of their customers,” says Ken Munson, co-founder and CEO of Sunverge Energy. “Our newest Solar Integration System gives utilities and solar providers more options for linking multiple systems into a virtual power plant to shift peak load and provide other benefits to the homeowner and grid.”

The new SIS, which will be available this summer, supports multiple lithium-ion battery chemistries and a wide range of storage capacities. Sunverge says that the upgraded product is lighter, more modular and easier to install than its predecessor and that it adheres to the latest performance, reliability and safety standards. Further, the system is suitable both for installation into existing solar systems and for packaging with new solar panels.

According to Sunverge, all SIS models offer an extensive array of grid services currently available, including the following:

– Back-up power mode: Automatically isolates from the grid in the event of a loss of grid power then delivers power to the site with no interruption in service;

– PV self-consumption mode: Automatically manages home energy to maximize the value of solar installation while maintaining grid connection for reliability and consumer savings;

– PV self-consumption with grid leveling mode: A variation of PV self-consumption that maximizes the value of solar installation while simultaneously smoothing imported and exported energy flows to and from the grid;

– Time-of-use bill optimization mode: Automatically optimizes energy use around a defined time-of-use-rate tariff for the financial benefit of the consumer;

– Grid non-export mode: Modifies system behavior to account for non-export interconnection requirements, balancing home load, required solar and excess solar in real time. The system has the controls to automatically turn off PV when storage is full and the home is fully powered – a feature that allows consumers in Hawaii to take advantage of recently enacted tariffs; and

– Peak shifting mode: Shifts the site or fleet peak load to an earlier or later time to better match the grid side energy capacity and constraints of the distribution network. Reduces peak load at an individual end user site or across the grid, with additional controls available to shape aggregate loads to meet the grid’s specific needs.

The company holds that these services maximize the efficient use of renewable or conventional energy and significantly increase the economic value of energy storage.
