Why Home battery Storage Become A Choice For More Families?
What is home battery storage?
Home battery storage, also known as residential battery storage, refers to batteries installed in homes to store electricity from solar panels or the grid and power the home. The stored electricity can be used during power outages or times when electricity rates are higher.
Residential battery storage systems typically include rechargeable lithium-ion battery packs, an inverter to convert the battery’s DC power to AC power, and a control panel to monitor and manage the flow of electricity. When the home generates more electricity than is needed, usually from solar panels, the excess is used to recharge the battery packs. During times of higher energy demand in the home or when utility power is offline, the stored electricity from the battery packs is available.
The advantages of using home battery storage
Compared to solely relying on the public utility grid or a diesel generator, home battery storage provides better reliability and cost savings.
- Reliability: Home battery storage provides backup power during utilities outages, ensuring essential appliances and devices stay powered. Outages on the main grid are becoming more frequent due to extreme weather or infrastructure issues. A home battery storage system guarantees uninterrupted access to electricity.
- Lower energy costs: Households with battery storage are able to store excess solar energy during the day and use it in the evening when electricity rates increase. This avoids high prices charged by utilities during peak demand periods. Over time, the energy cost savings from self-consumption of solar power can offset the upfront costs of a home battery system.
- Reduced carbon footprint: By utilizing stored solar energy instead of power from the grid which usually comes from fossil fuel power plants, home batteries diminish a household’s carbon emissions. This is far greener than diesel generators which release significant greenhouse gases and pollutants.
- Lower maintenance: Home batteries have no gasoline, oil, or engine maintenance compared to diesel generators. The batteries also operate very quietly without noisy fumes.
How does home battery storage work?
The usual storage process for household batteries includes:
Solar panels on the roof generate electricity from sunlight during the day and excess power is used to charge the battery packs.
When solar power is unavailable at night or on cloudy days, the stored electricity in the battery packs is inverted to AC power and used to power the home.
Any excess battery charge beyond what is needed can be sold back to the grid through net metering programs, providing an additional source of credits or income for homeowners.
During an outage, the battery seamlessly powers critical appliances disconnected from the main grid in backup mode.
Can I still use home battery storage if I don’t have solar panels at home?
Of course YES.
For households connected to the traditional electric grid:
Batteries can store inexpensive electricity during off-peak hours, when utility rates are lower, and use that power during peak hours to avoid higher prices. This time-based energy arbitrage alone can results in utility bill savings over time.
The battery acts as a backup power source during utility outages, ensuring crucial appliances like lights, fans, refrigerators stay running when the grid is down. This provides peace of mind.
Some utilities offer demand response programs where consumers get paid for allowing the utility to discharge power from their home batteries during times of peak system demand. This helps prevent brownouts.
In summary, residential battery storage serves as a reliable, cost-effective and sustainable complement to traditional power sources for more families. As the technology advances, it is becoming a sensible option for households seeking energy independence and savings.
