Commercial energy storage isn't always straightforward. Manufacturing facilities and other energy-intensive businesses need substantial battery capacity to keep operations running efficiently. But finding a system that offers enough storage, is practical to install and can adapt as a business grows can be a challenge.

Meeting these considerations are a challenge, but not impossible, especially if you’re using the SigenStack by Sigenergy. As the name suggests, SigenStack takes a modular approach to commercial battery storage. Rather than relying on one large, fixed-size unit, its stackable design allows businesses to build a system around their energy requirements, with the flexibility to expand as those needs change.

Each stack can accommodate up to seven 12.06kWh battery modules, with a maximum of 21 modules across a single system. That's an impressive 253.26kWh of battery storage. And if that's not enough, capacity can be expanded further using a Sigenergy DC Combiner Box, which allows up to four systems to be connected together.

At the heart of the system is Sigenergy's 125kW three-phase hybrid inverter, which intelligently manages the flow of energy between the solar panels, battery storage and the facility's electrical supply, helping ensure power is available where and when it's needed

The modular design offers practical installation benefits, making it easier to configure and install than a single, large commercial battery unit.

Of course safety is just as important as capacity when it comes to commercial batteries. The SigenStack incorporates six layers of protection to help safeguard the system, including fire protection. This is an important consideration for businesses investing in large-scale energy storage.

A great example of SigenStack in action can be found at Jack's Gelato's new manufacturing facility in Cambridge.

Making ice cream on a commercial scale takes plenty of energy; the site currently receives a 100A electricity supply from the grid, but peak production demand can reach 130A. This energy limitation, and the additional sustainability benefits, led to Jack’s installing a solar and battery storage system featuring 21 SigenStack battery modules. 

By combining solar generation with battery storage, Jack's Gelato can make better use of the energy generated on site. Excess solar energy can be stored in the batteries and used when production demand increases, helping to bridge the gap between grid supply and energy requirements.

The system was installed in July 2026, and the early signs are encouraging. On a November morning, following several cloudy days, the batteries were still around half full. It's a promising indication of how the solar and storage system is helping to provide an ongoing supply of energy for the facility.

Every commercial site has different energy requirements. Whether you're running a manufacturing facility, expanding production or looking to make better use of on-site renewable energy, having a storage system that can adapt to your needs is a real advantage.

With its modular design, substantial storage capacity and integrated safety features, SigenStack offers a flexible solution for businesses looking to take greater control of their energy use.
