Battery Energy Storage Systems (BESS)
The task of stabilizing the power grid and the efficient use of energy has become a global concern
Energy storage systems come in many forms but the most common, and most practical, are battery systems. Technology is moving at an incredible pace, and this is particularly true with batteries. The development of lithium-ion is overtaking traditional lead-acid batteries providing longer life and increased capacity. Coremax develops and provides all the major components of energy storage systems, which are used to create the most innovative and environment-friendly solutions for a sustainable and clean future. CMX offers a wide range of energy storage solutions (ESS Solutions) such as Uninterruptible Power Supply (UPS), Switchgear, and Micro Grid Power.

Battery Energy storage systems have many benefits.
By making solar and wind more reliable and predictable, they can:
- ★ Increase the potential applications for solar and wind power, even to commercial facilities requiring “mission-critical” power systems.
- ★ Further, reduce your dependence on the electrical power grid as well as associated costs.
- ★ Improve predictability and make your operation more resilient.
- ★ Reduce downtime and the loss of productivity that accompanies it.
- ★ Save energy costs by using grid power during off-peak periods.
- ★ Reduce Demand Charges from the utility.
Coremax Energy Storage Solutions can work with you to plan, design, and install your storage system. Whether that's as a stand-alone means of storing cheap off-peak energy, as a retrofit into your existing solar setup, or as a complete generation and storage solution.
Low voltage Battery Storage system
Battery packs that work with 48 volt operating voltage are common here. 12V or 24V storage batteries are available for mobile applications. Today LiFePO4 - lithium storage batteries are preferably used, as they have a larger working area than lead-acid batteries. Lithium batteries have a discharge depth of up to 10%. - Depth of Discharge (DoD). These are most popular or standard for low voltage BESS. People normally need these low voltage battery system for small solar energy storage. hence these 12v, 24v or 48v battery sytems are widly use for residential scale 10kwh, 20kwh, 30kwh. Expandable storage systems can be interconnected to form an overall system> 100 kWh.
High Voltage LiFePo4 BESS
Why use high voltage lithium battery systems.
Let’s give an example for solar lithiun storage battery system field, imagine that when an 8kW hybrid solar inverter is used with a lithium battery, as a low voltage storage system, the battery DC voltage is usually 48V or 51.2V for home solar applications. Even if we use a relatively larger nominal current, such as 100A, The maximum power that the battery can provide is 5kW (51.2V x 100A = 5.12kW), and this value cannot meet the maximum output power of the inverter. Moreover, there are so many commercial energy storage applications where the power system output power is such as 30kW, 40kwh, 60kW, 100kW or even 500kW power capacity. In these application scenario, we must use a HV lithium battery system to lower down the discharge current.
Why Solar + Storage?
Solar panels alone are a great fit for many businesses, but not all customers can benefit from them. Manufacturers running energy-intensive machinery at night, for example, require a more advanced solution to manage their power needs. Battery storage can provide that solution by extending the usefulness of solar energy.
Battery energy storage systems are more than just batteries. They are at the cutting of edge of the renewable energy industry. Battery storage can be used for emergency backup, off-grid homes, and more, but its most important application is peak shaving.
Peak shaving cuts expensive demand charges by reducing electricity consumption during peak usage times like summer afternoons. Not all electric users have demand charges, but for businesses with demand charge tariffs, they can be very expensive. According to the National Renewable Energy Laboratory (NREL), demand charges can account for 30% to 70% of a customer’s utility bill.
While solar arrays alone can help alleviate demand charges, they aren’t as effective as battery energy storage. Battery energy storage systems can guarantee that no power above a predetermined threshold will be drawn from the grid during peak times. They can automatically detect when power usage exceeds a predetermined threshold and switch from the grid or solar panels to batteries until the additional demand is over. When demand goes back down, the batteries recharge.
