Energy Storage Systems

Full-Stack Battery Energy Storage Systems for Reliable Power

Built for the energy economics of real sites

A Battery Energy Storage System stores energy from solar, the grid or a hybrid setup and makes it available when power reliability, backup or smarter energy usage is needed. For Exicom, BESS is focused on practical commercial, industrial and residential applications. Helping sites manage peak demand, reduce diesel dependence, use more solar energy and keep critical loads running.

A complete energy storage system, engineered as one

BESS performance depends on more than the battery. Battery modules, BMS, PCS, EMS, safety systems and service support need to work together as one integrated system. Exicom’s systems-thinking approach brings these layers together for reliable site-level performance.

Why are businesses and communities turning to energy storage?

Energy demand is rising. Solar is scaling rapidly. Diesel backup is becoming more expensive and harder to justify. Power users are being pushed toward smarter, more flexible ways to manage consumption. BESS sits at the centre of this shift, turning stored energy into a practical asset for reliability, savings and control.

Segments covered by Exicom BESS solutions

Commercial and Industrial Energy Storage

You’ve relied on diesel generators and conventional backup systems for years. But your energy costs, peak demand charges and uptime expectations are changing. C&I BESS helps factories, offices, campuses, hospitals, retail sites, telecom infrastructure and other facilities improve power reliability, reduce diesel dependence and make solar energy storage more effective.

Relevant applications

Peak demand saving, ToD arbitrage, Load shifting, Backup power, Critical load support, Diesel generator optimization, Solar energy storage

Frequently asked questions

What is a Battery Energy Storage System?

The Battery Energy Storage System (BESS) is a device that stores electricity from solar, grid or hybrid power sources and makes it available when needed. It can support backup power, peak shaving, solar self-consumption, ToD-aware energy usage and smarter energy management.

This is some text inside of a div block.
How does BESS improve energy economics?

BESS can help users manage peak demand, minimize diesel generator run time, maximize solar energy use and use stored energy when it is most advantageous. The economics of it relies on the load profile of the site, the solar capacity, tariff structure, backup requirements and size of the system.

This is some text inside of a div block.
Can BESS work with rooftop solar?

Yes. BESS can store extra solar energy generated during the day and make it available later, such as in the evening, during peak demand or outages. This increases the self-consumption of solar and extends the utility of rooftop solar beyond hours of daylight.

This is some text inside of a div block.
How does BESS reduce diesel dependence?

BESS can be employed for hybrid power use and short-term backup, and can reduce the need to run diesel generators with every outage or load change. This can reduce the costs of fuel, maintenance, noise and emissions.

This is some text inside of a div block.
Is BESS suitable for commercial and industrial businesses?

Yes. C&I customers can use BESS for: peak demand savings, ToD arbitrage, diesel generator optimization, critical load backup, solar energy storage, and energy cost reduction. This is especially true for sites where energy cost, power quality and uptime are important considerations.

This is some text inside of a div block.
Can BESS be used for homes and residential communities?

Absolutely. Residential BESS can increase solar self-consumption, provide battery back-up for home use, and Time-of-Day Aware Energy Consumption and Grid Independence Reduction Applicable to housing societies, premium apartments, and individual homes.
