What is Energy Storage Battery
Energy storage is the capture of energy produced at one time for use at a later time to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an energy storage battery.
Benefits of Energy Storage Battery
Environmental benefits. Energy storage battery has many environmental benefits that can make it a valuable tool for meeting sustainability goals. By improving the overall efficiency of the power grid, storage accelerates the broader adoption of renewable energy. On a more local level, an energy storage battery has no emissions, so it can be placed anywhere in a facility with no immediate environmental or air quality impacts. And if paired with solar PV, not only will the power be GHG-free, the combined system is eligible for federal investment tax credits.
Demand charge reduction. Depending on location, many commercial and industrial facilities are subject to demand charges on their energy bills. These charges are based on the 15-minute period in which the demand for energy is highest throughout the day and in some cases, can account for 50 percent of the total energy bill. While energy efficiency or solar PV can reduce total electricity consumption, these benefits do not always coincide with a building’s peak use. Energy storage battery, especially those paired with intelligent software, can track a facility’s load and reduce demand charges by dispatching battery power during periods of peak demand, effectively “flattening” the load.
Participation in demand response programs. Demand response for commercial and industrial facilities traditionally involves ratcheting down usage at times of peak demand. Energy storage battery can enable participation in demand response markets without impacting on-site energy use or operations. By responding to utility price signals, storage systems can increase financial return from participating in DR programs, while also benefiting the grid overall.
Maximizing time-of-use rates. Energy storage battery can shift consumption of electricity from expensive periods of high demand to periods of lower cost electricity during low demand. This reduces the risk of lowering the value of on-site solar if tariff structures change over time, and peak demand periods shift to the evening when the sun isn’t shining. This also allows facilities to make the most of time-of-use pricing and reduce tariff structure change risk to electricity cost.
Emergency backup — resilience. Planning for emergency backup power is an essential part of a resilience plan. Historically, commercial and industrial facilities have invested significantly in local emergency backup infrastructure. With advanced storage solutions on the market today, there may be opportunities to upgrade this infrastructure to provide not only emergency backup, but also a host of other money-saving and money-making solutions. And by using this infrastructure on a daily basis for demand charge reduction, its reliability and availability in the event of an outage can be increased as compared to a standalone battery system and diesel generator that is only used during an outage.

Navigating the Choices: How to Select the Right Energy Storage Battery for Your Needs
Capacity & Power
A energy storage battery capacity shows how much electricity it can hold in kilowatt-hours (kWh). But it's not just about the storage capacity; you must also consider the battery's power rating. This tells you how much energy can be released at once, giving you an idea of how many appliances you can use.
Depth of Discharge (DoD)
This factor represents how much energy storage battery capacity can be used without negatively affecting lifespan. A higher DoD value means you can use more of your battery's capacity.
Efficiency
The round-trip efficiency metric shows how much energy the battery can use after charging and discharging. Higher efficiency means more usable electricity and better overall value.
Lifespan and Warranty
Energy storage battery life expectancy and warranties are critical to your investment. Look for options that offer the best combination of cycle life (how many charge-discharge cycles a battery can handle before performance declines) and warranty conditions.
Evaluate Your Energy Usage: Examine your electricity bills to grasp your household's energy consumption patterns. Pay attention to seasonal fluctuations to determine your peak and off-peak energy demands.
Determine Essential Loads: Decide which appliances and systems you wish to keep operational during a power outage. This may include refrigeration, lighting, and WiFi connectivity.
Estimate Your Solar Panel Output: Consider the electricity production of your panel setup. This will help you gauge the power available for storage.
Plan for Future Energy Demands: If you foresee changes in your energy usage, such as adding a vehicle or expanding your residence, factor these into your planning.
Seek Advice from Experts: Energy professionals can offer insights and conduct thorough assessments to recommend a energy storage battery size that aligns with your requirements.
Energy Storage Battery & Maintenance Tips
Disconnect your batteries in your equipment when not in use. Disconnecting your batteries will eliminate any parasitic loads that may drain your batteries down while in storage. Batteries left in a discharged state are subject to sulfation which may reduce life and/or permanently damage them.
This step is absolutely critical! Always store your batteries FULLY CHARGED. Batteries have a self-discharge rate and need to be maintained while stored. Prior to disconnecting your batteries, make sure they are fully charged. Every other month, connect your batteries, plug in the charger, and run your batteries through a full charge cycle.
Extreme hot and cold weather can affect your batteries. High Temperatures will accelerate chemical activity in your energy storage battery significantly during storage. This will increase the self-discharge rate, potentially causing a reduction in capacity and/or shorter energy storage battery life. Cold Temperatures conversely will cause slower activity, which may make a energy storage battery vulnerable to freezing if not kept fully charged. For example, if you know your garage exceeds 100 degrees during the summer, or gets below 35 degrees in the winter, you should bring them inside your home where they can be insulated.
Regularly inspect your energy storage battery for signs of corrosion. Corrosion can prevent your energy storage battery cables from making a strong connection over time. Keep the energy storage battery clean by wiping it down during your inspection as well.
Charge your batteries every day or every night, even on days with little use. Whether your batteries are being used all day or on occasion throughout the day, a full charge allows them to perform at their best and increases the lifespan of the batteries. Charging them completely every day or night will ensure that they do not degrade over time. Keep in mind that while your energy storage battery charger may show 90% after just a quick charge, it is the last 10% of charging that takes the longest. Once the green light is visible, leave your batteries on charge for an extended period to ensure a full charge has taken place. If your equipment is not used every day, then charge fully after each use.
Lead-Acid
Lead-acid batteries have been in use for decades and are one of the most common types of battery used in automotive and industrial applications. They have a low energy density (meaning they cannot hold much energy per kg of weight), but remain both cost-effective and reliable and thus have become a common choice for use in a home solar setup.
Lead-acid batteries come in both flooded and sealed varieties and can be classified as either shallow cycle or deep cycle depending on the intended function and safe depth of discharge (DOD). Recent technological advancements have improved the lifespan of these batteries and lead-acid continues to be a viable option for many homeowners.
Lithium-Ion
The technology behind lithium-ion batteries is much newer than that of other battery types. Lithium-ion batteries have a high energy density and offer a smaller, lighter and more efficient option. They allow the user to access more of the energy stored within the battery before needing to be recharged, making them great for use in laptops and phones—and in your home.
Nickel-Cadmium
Nickel-cadmium batteries are rarely used in residential settings and are most popular in airline and industrial applications due to their high durability and unique ability to function at extreme temperatures. Nickel-cadmium batteries also require relatively low amounts of maintenance when compared to other battery types.
Flow
Flow batteries depend on chemical reactions. Energy is reproduced by liquid-containing electrolytes flowing between two chambers within the battery. Though flow batteries offer high efficiency, with a depth of discharge of 100%, they have a low energy density, meaning the tanks containing the electrolyte liquid must be quite large in order to store a significant amount of energy. This size makes them a costly and impractical option for most household use. Flow batteries are much better suited to larger spaces and applications.
Energy storage battery hold the key to unlocking the full potential of renewable energy. As sunlight is converted into electricity by solar panels, any extra energy generated during sunny periods can be captured and stored within these batteries for future use. This also ensures a continuous power supply all year round.
Inside the energy storage battery, chemical reactions take place to store the surplus electricity as potential energy. So, when electricity is needed when the sun isn’t shining, such as during nighttime or overcast days, the stored energy is converted back into usable electricity and readily supplied to your home.
By allowing homeowners to maximize their solar energy consumption, energy storage battery increase the reliability of solar power systems and decrease dependence on the conventional power grid. The ability to store and utilize solar energy even during periods of limited sunlight makes solar power a more practical and efficient choice for renewable energy.
Things to Look for When You're Picking a Energy Storage Battery
Type or Material
Among the types of batteries to choose from, each type offers a different major advantage. Weighing these pros and cons can help you decide which style is right for you. If you're looking for something compact and longer-lasting, lithium-ion may be right for you. Lead-acid might be better for those conscious of more immediate budget constraints.
Energy Storage Battery Life
The “lifespan” of any energy storage battery is multifaceted; the age, type, quality and depth of discharge of the battery all contribute to its longevity. Referring to the manufacturer's specifications for a batteryenergy storage battery can help you determine how long it's likely to last.
In general, lead-acid batteries can last anywhere from one to 10 years depending on how they're used. Lithium-ion batteries typically last seven to 15 years.
Depth of Discharge
Depth of discharge refers to how much of a battery's stored energy is used before the energy storage battery is recharged. Typically, the deeper the energy storage battery is discharged, the shorter its lifespan will be.
Batteries often come with both a cycle life estimate (indicating how many cycles it will last given a particular depth of discharge) and a recommended maximum depth of discharge.
Efficiency
Solar systems and batteries are not 100% efficient when transferring and storing the collected solar energy from panels to batteries, as some amount of energy is lost in the process. Depending on the amount of energy you're able to generate from your panels and how your system is configured, it may be worth investing in a more expensive, more efficient battery. This can help save money long-term. Your solar panel efficiency and energy storage battery capacities will be calculated and your system explained to you by any competent sales and installation team, but our solar resources can help you understand exactly how your system works, too.
