Whether you’re a business owner looking for renewable energy solutions, an industry professional keeping up with the latest developments, or an enthusiast curious about the future of sustainable technology, this article is designed to provide you with valuable insights. Let’s begin our exploration by delving into these frequently asked questions.

1. What is a commercial energy storage system?

Commercial storage systems are a clean technology designed to store electricity for later use. These systems are the backbone of a business’s energy infrastructure, capable of storing power when demand is low and dispatching it when demand is high. This ability to control when and how power is used provides significant advantages that allow businesses to operate more efficiently and sustainably.

Commercial battery storage systems use advanced lithium-ion battery technology and are installed on business premises. The stored energy can come from a variety of sources, including the grid during off-peak hours or solar panels. Once stored, this energy can be used in a variety of ways: it can be dispatched during peak demand hours to reduce energy costs, used as a back-up power source during power outages, or even fed back into the grid in some cases.

Commercial storage systems are not only about energy independence, but also about smart energy management. These systems can be programmed to optimise energy use based on a variety of factors, such as energy prices, peak demand times and the specific energy needs of a business. Essentially, commercial battery storage systems allow businesses to take control of their energy use, improve efficiency, reduce costs and support sustainability efforts.

WHC SOLAR’s 100kW/215kwh is a proven C&I energy storage system solution that is already on the ground and in operation in Nigeria, providing businesses with a reliable and efficient solution to manage their energy needs while making the transition to renewable energy.

2. How do commercial energy storage systems work?

Commercial energy storage systems work principle by getting and storing electrical energy and then providing that energy when needed. This process involves several stages:

Charging: The first is to charge the system. This involves taking power from some source (either from the grid or from the solar) and storing it in the system’s lithium batteries. The energy in these lithium batteries is usually stored as chemical energy, which can be converted back into electrical energy when needed.

Storage: Once charged, energy is stored until it is needed. The advanced battery technology used in solar systems can store large amounts of energy for long periods of time. The stored energy can be used at any time, providing flexibility in managing energy demand.

Discharge: When energy is needed (e.g., during peak demand hours, blackouts, or when the solar panels are not generating energy), the system discharges, converting the stored chemical energy into electrical energy and delivering it for use by the load appliances.

Management: Most commercial energy storage systems also have a management component. This is usually a web or app that manages the flow of energy and allows the user to decide when to charge and discharge based on a variety of factors such as energy prices, demand patterns and the overall energy needs of the organization.

WHC SOLAR’s 100kw/215kwh commercial energy storage systems are equipped with an advanced energy management system to dynamically and intelligently manage your system. The system is designed to efficiently manage energy use, storing power when demand and prices are low and supplying power when demand is high or power outages occur. Making the method of managing your business’ energy needs more reliable, efficient and cost-effective.

3. What benefits of using commercial battery storage system?

Commercial battery storage systems offer numerous benefits to businesses, making them an increasingly popular choice in today’s energy sector. Here are some of the key benefits:

Energy cost savings: These systems can provide significant cost savings by charging during off-peak hours when energy prices are low and discharging during peak demand hours when prices are high. This practice can significantly reduce energy costs for businesses.

Reducing pressure on the grid: Grid instability is a common problem in various countries in Africa. A strategic approach to easing the strain on the grid is to expand the installation of commercial and industrial energy storage systems. Grid stress can be effectively reduced by installing C&I outlets in communities at the point of energy consumption.

Reducing carbon emissions: By optimizing energy use and efficiently utilizing renewable energy sources, commercial battery storage systems can help businesses reduce their carbon footprint and achieve sustainable development goals.

4. How much energy can commercial storage system store?

The amount of energy that can be stored in a commercial energy storage system varies depending on the specific system and its configuration. It is usually measured in kilowatt-hours (kWh), a unit of energy that represents the amount of work that can be done in one hour with one kilowatt of power.

Small commercial battery storage systems may have capacities in the tens of kilowatt-hours, with WHC SOLAR’s commercial and industrial energy storage systems, for example, having a minimum of 61 kWh of capacity for small businesses or facilities. Larger systems designed for large operations or industrial use can store hundreds or even megawatt-hours of power. The required capacity depends on the energy needs of the business, changes in energy supply and demand, and the business’s goals for using the system, such as backup power supply or cost savings.

5. How long can commercial energy storage systems store?

The duration of energy storage in a commercial solar system depends greatly on the system’s programme design. While most commercial and industrial energy storage systems are designed for day-to-day energy storage – charging during periods of low demand or high solar production, and discharging during periods of high demand or low solar production – if not in use, they can theoretically hold a longer period of Electricity.

It is important to note, however, that the best use of these systems is not to store energy indefinitely. They are designed to actively manage energy supply and demand, which involves regular charging and discharging.

On the other hand, the life cycle of these systems can vary depending on a number of factors, including the quality of the product, management of the charging and discharging cycles, environmental conditions and the level of maintenance. Typically, well-maintained C&I energy storage systems have a lifespan of 10 to 25 years.

WHC SOLAR’s commercial and industrial energy storage system is an example. Unlike other systems, it is equipped with a patented Battery Control System (BCS). This advanced technology actively manages each battery within the system, monitoring its state of charge and health. This means that the system can intelligently decide which batteries to use at any given moment, allowing the batteries to rest when they are not needed – thus improving the overall safety and performance of the system.

This proactive management approach not only improves the safety of the system but also significantly extends its lifespan. The Battery Control System (BCS) ensures that the system provides reliable and efficient energy management over a longer period of time, making it an ideal long-term energy solution for organizations.
