Solve Your Current Power Outages With a Home Energy Storage System

These systems capture and store generated electricity or heat from a solar power system, enabling you to use it later when the cost of electricity from the grid is higher or your solar array isn’t producing.

Reduce Your Utility Bills

Home energy storage systems allow you to store solar power generated by your roof-mounted or off-grid solar system during daylight hours and use it later. This can help reduce your utility bills during peak times of the day, or when the cost of grid-produced electricity is higher, and it can also keep a portion of your home powered in case of an outage.

Electricity costs are composed of two main components: supply and delivery. You pay for the cost of electricity generation, then a utility covers the cost of delivering that electricity to your home.

Battery storage systems can help you lower your utility bill by storing the electricity your solar system produces when prices are low and then using it when prices are high, or allowing you to charge your batteries when you’re on an incentive-based Net Energy Metering rate or Time-of-Use rate.

Some utilities offer incentives for installing energy-storage systems and are also experimenting with ways to reward customers who feed power from their batteries into the grid during peak demand periods. These programs, called “bring your own battery” programs, are offered in several states, including Massachusetts and Rhode Island.

Avoid Power Outages

Home energy storage systems are a great way to avoid power outages. They store power that homeowners generate from their own solar system, and from the grid when electricity is cheaper.

A typical home battery system includes a battery, inverter, wiring and backup power configuration, and energy management software and communication technologies that automate charging and discharging of the battery and monitor system performance.

In addition to avoiding power outages, energy storage can also save utilities and electricity consumers money. By using stored energy during brief outages, businesses can continue normal operations and residents can save on food and medicines as they’ll have electricity to run refrigerators and other equipment.

During an outage, the excess energy from your solar panels will power your most essential lights and appliances. Any remaining energy will be redirected to charge your home’s battery. This battery will then be used again when there’s enough sunlight to power your home’s solar panels again.

Increase Your Home’s Value

A home energy storage system can be a game changer in your life and your home’s value. Depending on the model you choose, a battery system may comprise a battery, inverter, wiring and backup power configuration, and energy management software.

A typical home battery system can store anywhere from 1 kilowatt hour (kWh) to 10 kWh, and it is usually configured to run your entire household or only the most essential items during a power outage. Generally speaking, a lithium-ion battery is the technology of choice due to its light weight, high energy density, and ability to recharge quickly and easily.

One of the best things about a battery system is the savings you can get on your utility bills over time. A study by the National Renewable Energy Laboratory found that homes with solar panels and other energy-saving technologies have a yearly increase in value of over $20 for every $1 saved on your electric bill.

Protect Your Family

With a home energy storage system, you can keep your lights on and your phone charged even during power outages. It can also help you avoid paying high utility bills when the grid is strained.

Many systems use lithium-ion batteries, which are a popular technology for appliances such as cell phones and electric vehicles. These batteries are lightweight, safe, and durable.

In addition, home battery systems generally include energy management software and communication technologies that automate charging and discharging. These software algorithms determine when to store electricity in the battery and when it’s better to discharge it, based on your energy consumption patterns.

You can configure your home energy storage system to either power your entire house during a grid outage or only essential loads for backup power. If you choose a “whole home” setup, you’ll need to reduce your electricity usage during a power outage so the battery doesn’t run out of charge. However, a “partial home” configuration allows you to power only your virtual devices during the outage and doesn’t require you to make changes to your electricity usage.
