What is Home Storage Battery？

 

Home energy storage consists of a battery that allows you to store surplus electricity for later consumption, and when combined with solar power generated by your photovoltaic system, the batteries allow you to store energy generated during the day for use around the clock. Since battery energy storage systems are capable of optimizing the use of electricity, they ensure the most effective operation of your home solar power system. At the same time, they also guarantee continuity in case of temporary disruptions in the power supply, with extremely low response times. Home energy storage further supports energy self-consumption: the surplus energy produced during the daytime from a renewable source can be stored locally to use at a later time, thus reducing the degree of dependency on the electricity grid. An energy storage battery therefore makes self-consumption more effective.

Benefits of Home Storage Battery

 

Off-grid Independence
When you have a battery, your energy is yours. Your home becomes greener by using your own renewable energy. In some circumstances, when power is in higher demand, you can even sell it back to the grid.

 

Lowers Utility Bills
Pairing your solar panels with a battery saves you as much as 90% on your energy bills. If you ever need extra power, too, your battery can store energy from the grid during cheaper and greener off-peak times, thanks to smart scheduling.

 

Never Lose Your Solar Energy
Glorious summer weather is fantastic for your solar panels. That’s obvious. But you want to be out enjoying the sun, too, without the worry of not using the energy your solar panels are collecting.

With a battery, your solar power is never wasted. It is stored whether you’re in or not, meaning you can be out enjoying the sun - just like your solar panels.

 

Energy Day And Night
Storing your solar power means you never need to rely on whether the sun is up to utilise it. Day or night, a battery gives you energy whenever you need it.

 

Set It And Forget It
Solar panels and home batteries need little to no interaction or maintenance, meaning, once installed, the only thing you need to do is reap the benefits.

 

Everyone (and Everything) Benefits
From saving energy and money to decreasing your carbon footprint – you, your home, and the world benefit. It’s a win-win!

 
Types of Home Storage Battery
Lithium ion battery storage system

As its name implies, the lithium-ion battery uses lithium salts for the electrolyte. The cathode electrode is a lithium compound, while the anode is typically graphite.

Cathode options vary from lithium iron phosphate and lithium cobalt oxide to lithium manganese oxide—the manganese oxide-based type offers better characteristics and finds preferred use in specialized applications.

Although a more expensive option, the LI-ion is one of the most used BESS types, with diverse uses ranging from homes to commercial and industrial sectors.

Lead acid battery storage system

These BESS systems use batteries consisting of lead electrodes and sulfuric acid (H2SO4) as the electrolyte. The typical lead acid-based BESS lasts between 5 and 10 years but requires regular maintenance over its lifetime.

Lead acid storage batteries are also less efficient than the Li-ion types (about 85%) and have a low DOD of around 50%. They also need periodic charging when not in use for extended periods to maintain them.

Nickel cadmium battery storage system

Nickel-cadmium battery storage has a nickel oxide anode with a nickel hydroxide separator. The cathode is cadmium metal, and the electrolyte is potassium hydroxide, an alkaline.

It’s good to note that, apart from the cadmium type, a nickel-based storage battery can be a hydride type. The nickel hydride battery uses a hydride (an alloy that can absorb hydrogen) for the negative electrode in place of cadmium.

The hydride type of the nickel-based types of storage batteries offer better properties, which include higher energy density and environmental friendliness

Sodium-sulfur battery storage system

These battery storage systems use molten sodium for the cathode and liquid sulfur for the anode or negative electrode. The electrolyte is sodium alumina, which must melt to allow ions to move between the electrodes.

Because it uses liquid materials, this battery operates at higher temperatures above 300 degrees Celsius and includes heaters to liquefy the solid electrolyte.

The energy density of sodium-sulfur BESS systems is comparable to that of Li-ion batteries, except they have a shorter lifespan and require high heat levels to liquefy the solid sodium electrolyte.

Flow battery storage system

Two tanks contain the electrolyte in a flow battery storage system, with an ion exchange membrane separating them to facilitate the reaction that stores energy.

During charging, the current oxidizes the chemical compounds in one container and reduces those of the other. The reactions convert the charging current into stored chemical energy.

Various technologies are available for flow BESS types based on the chemicals used for the electrolyte. It can be a vanadium or zinc-bromine ion solution. The battery can also be an iron-chromium type.

The use of energy storage batteries can reduce carbon emissions, reduce dependence on fossil fuels, and contribute to the realization of a green, low-carbon energy future.

Components of Home Storage Battery

 

 

Battery
The #battery is the heart of any battery storage system. It stores the energy generated by renewable sources like solar panels or wind turbines for later use. There are several types of battery technologies available, including:
●Lead-acid: A tried-and-tested technology, lead-acid batteries are affordable and widely available. However, they have a relatively short lifespan and lower energy density compared to other options.

●Lithium-ion: These batteries have a higher energy density, longer lifespan, and faster charging capabilities than lead-acid batteries. They're also lighter and more compact, making them a popular choice for residential and commercial applications.

●Flow batteries: This emerging technology stores energy in liquid electrolytes that flow through a cell stack. Flow batteries have a long lifespan and can provide large-scale energy storage, making them suitable for grid-scale applications.

 

Battery Management System (#BMS)
The Battery Management System (BMS) is responsible for monitoring and controlling the battery's performance. It safeguards the battery from damage caused by overcharging, over-discharging, overheating, and short-circuiting. A BMS also provides valuable data about the battery's state of charge, health, and temperature, which can be used to optimize the system's performance and extend its lifespan.

 

Inverter
An inverter is a critical component of a battery storage system, as it converts the direct current (DC) electricity stored in the battery into alternating current (AC) electricity that can be used by household appliances and the grid. There are two main types of inverters:
●Stand-alone inverters: These inverters work independently from the grid and are typically used in off-grid applications or as backup power sources.

●Grid-tie inverters: These inverters synchronize with the grid, allowing battery-stored electricity to be fed back into the grid when demand is low or during peak pricing periods.

 

Charge Controller
A #chargecontroller manages the flow of electricity between the renewable energy source, the battery, and the inverter. It ensures the battery is charged efficiently and protects it from overcharging, which can shorten its lifespan and reduce performance.

 

Monitoring System
Monitoringsystems provide real-time data about the performance of a battery storage system, including the battery's state of charge, energy consumption, and overall system efficiency. This information can help users optimize their energy usage, identify potential issues, and maintain the system effectively.

 

Electrical Components And Wiring
Electrical components such as switches, circuit breakers, and wiring connect the various parts of a battery storage system and ensure the safe transfer of electricity. Properly installed and maintained electrical components are crucial for the system's safety and performance.

 

Enclosure And Mounting
The enclosure and mounting hardware protect the battery storage system from environmental factors like moisture, dust, and temperature fluctuations. A high-quality enclosure can also help prevent tampering and theft.

Material of Home Storage Battery

Your battery's chemistry refers to the primary compound used to store energy. Today, most home batteries use lithium-ion chemistries due to their high power density, though you may still find portable or car lead-acid batteries. Three types of lithium-ion battery chemistries are popular in home batteries:

 
 

Nickel manganese cobalt oxide (NMC)

NMC is today's most common home battery chemistry. Most homeowners choose NMC batteries for their relatively low price point and high energy density. However, they tend to have shorter lifespans and are less stable than other lithium batteries, making them slightly more prone to safety issues.

 
 
 

Lithium iron phosphate (LFP)

LFP batteries are quickly gaining on NMC batteries in popularity due to their relatively long lifespans, stability, and moderate price point. However, they often have lower energy densities than NMC batteries and tend to cost more.

 
 
 

Lithium titanate (LTO)

LTO batteries are new to the home battery market. They cost more upfront than NMC and LFP batteries and have lower energy densities but offer the longest lifespans, fastest charge times, and the highest level of safety because they're not flammable.

 
Process of Home Storage Battery

 

The Grid

The grid is the largest machine on Earth. Just three grids comprise the entire US power system, interconnecting thousands of power plants and millions of miles of transmission and distribution lines that deliver power to end users, like you.

 

Main Distribution Panel

Power from the grid enters your home through a single set of wires. The main distribution panel splits power from the grid and sends it along circuits to the rooms and appliances in your house. After installing a home battery, only certain larger loads remain connected directly to the main panel. Anything connected to the main panel (which includes everything in a home without a battery), is susceptible to a power outage.

 

Home Battery System

A home battery system acts as a buffer between the grid and your home. It charges from solar panels or the grid. In an outage, the battery instantaneously disconnects from the main panel and the rest of the electrical grid, creating a self-sustaining, personal grid that includes solar panels and the important things in the home. When the sun goes down, a home battery can power your home with stored solar energy, all night long.

 

Solar System

Photovoltaic solar panels convert sunlight into electricity. Because solar panels generate direct current (DC) electricity, an inverter is required to transform solar electricity into alternating current (AC), which is the type of electricity used in your home.

 

Critical Loads Panel

During installation of a home battery, a certified electrician installs a critical loads panel, which has the same function as the main distribution panel. The home battery powers the critical loads panel, which sends electricity to all of the important rooms and appliances in your home.

 

How to Maintain Home Storage Battery

Battery Management System (BMS): The battery management system (BMS) is a critical component of home energy storage. The BMS ensures that the battery is charged and discharged within safe limits, prevents overcharging or undercharging, and monitors the battery's temperature, voltage, and current. The BMS is usually monitored by the energy management system (EMS), as in the Franklin Home Power solution, to ensure that it is working properly and that the batteries are not being damaged.

 

Battery Replacement: A home energy storage system’s lifespan can vary depending on the type of battery and the frequency and magnitude of use. Regular monitoring of the battery's state of health, and replacement when necessary, is important to ensure that the system continues to perform at its best.

 

Cooling System: Most home energy storage systems have a cooling system that helps regulate the temperature of the battery. Regular cleaning of the cooling system and checking its operation is important to ensure that the battery is not overheating and that the system is operating efficiently.

 

Software Updates: Software updates are necessary to ensure that the home energy storage system continues to operate optimally and to address any security or performance issues. It is important to keep the system updated to ensure that it continues to perform at its best. Over-the-air (OTA) updates are optimal because they quickly provide the latest technology and remove the need for a technician to travel to every installation.

Residential Storage Batteries
Safety Considerations
 

Electrical Safety: Home energy storage systems use high-voltage batteries, which can pose a hazard if not properly handled. It is important to ensure that the system is installed and connected by a qualified electrician and that the electrical connections are properly made and maintained.

 

Fire Safety: Older lithium-ion batteries, which are used in some home energy storage systems, have a risk of thermal runaway and fire. Regular monitoring of the battery's temperature, voltage, and current, as well as ensuring that the system is installed and connected properly, can help reduce the risk of fire. Modern technologies, such as lithium-iron-phosphate (LFP), are much safer and remove almost all fire risks.

 

Battery Disposal: Home energy storage system batteries must be disposed of properly to avoid environmental hazards. Batteries should never be thrown in the trash, as they contain toxic chemicals that can harm the environment.

 

Carbon Monoxide: Some home energy storage systems use internal combustion engines, such as gasoline-powered generators, to charge the battery. These systems can produce carbon monoxide, a colorless and odorless gas that is toxic to humans. It is important to ensure that the system is installed in a well-ventilated area to reduce the risk of carbon monoxide exposure.
