Major Storage Integrator Trend: Cabinet Enclosures See an Uptick in Popularity

Cabinets are all the rage today. For energy storage systems,
anyway.

Traditionally, cabinet-based energy storage enclosures have been
more popular for smaller front-of-meter (i.e., those with around 10
megawatt-hours of capacity). But as the market comes to realize the
benefits of cabinets over containers, there is growing interest in
using this system housing for larger projects as well.

Each individual cabinet comes fitted with a limited number of
battery racks, along with an HVAC and fire detection and
suppression system, thus enhancing their safety profile. These
enclosures are designed to be completely walk-free and can only be
accessed externally, helping to ensure the safety of the personnel
installing or servicing these systems.

A couple of years ago, the interest in these enclosures was
spurred owing to compliance with NFPA 855 standards, but now most
vendors have come to recognize additional benefits of cabinet
enclosures.

Cabinets are usually shipped preloaded with batteries, as most
of the assembly and wiring work happens in the factory. Prefitting
these cabinets in a factory, which is a more automated and
controlled environment, leads to lower integration risks, higher
quality, lower engineering costs and faster installation and
commissioning.

In some cases, assembling a container on site can take as much
as 50 percent longer compared to installing a fully preloaded
cabinet, depending on the size of the project. As a result,
cabinets are becoming an obvious choice, particularly for projects
with tight commissioning timelines. The biggest challenge with
cabinet enclosures pertains to shipping.

Since these units come prefitted with battery racks, it can
sometimes be more expensive to ship these cabinets compared to
other containers, depending on the location of the project
site.

Several system integrators are already beginning to standardize
their cabinet-based products, thereby making them scalable. The
industry is increasingly moving from a bespoke approach to products
to a more standardized paradigm.
