Lithium-ion Battery Pack for Home Energy Storage

Lithium Ion Battery Pack For Home Energy Storage

What is House Energy Storage System?

Househol energy storage system is a home battery designed to store energy from solar or the grid, so you can use it anytime you want—at night or during an outage.

Ever since Househol energy storage system was popular a few years ago, more than a few homeowners have wondered what the buzz was all about. For solar array owners, the appeal of lithium battery storage makes sense. On sunny days, residential solar arrays often generate enough electricity to power a home. They have enough left over to sell back to the local utility.

Are Home Batteries Worth It?

The idea that the power could be stored and used later, rather than sold back to the grid, will become a more attractive option. Home storage batteries can help you cut your electricity bill, especially if you live in a sunny state. However, a home can only get to Net Zero energy by being powered with clean energy captured by solar panels and stored in batteries.

Stored electricity could fill the tank of an electric car or keep the lights on in homes and neighborhoods where the electric grid has gone down. This is the idea behind making your home more resilient. In addition, it can keep some essential electric-powered items, like your refrigerator and freezer, running in the event of natural or human-made disasters that are becoming more frequent.

As that same grid becomes more sophisticated, homeowners may even have opportunities to sell their energy to utilities during high-demand times, such as 5 p.m. to 8 p.m.

Solar-powered batteries have been around for a while. However, they are still a young but rapidly growing market now as manufacturers continue to ramp up production to meet increasing demand. No one company dominates the market; here’s a look at the current marketplace.

Be wary of marketing statements about how many days of power the battery offers, as that is entirely dependent on how much energy your home requires so that it can vary widely. The key to sizing is understanding how much power you will be using/drawing from the battery. Some homeowners see batteries to get off the grid, but that’s an unlikely scenario, at least with lithium batteries. These batteries typically only hold enough energy to power an average American home for hours, not days.

How Many Batteries Are Needed to Power a House?

The amount of battery storage required is based on your home’s energy usage. Energy usage is measured in kilowatt-hours over some time—for example, a home requiring 1,000 watts for 10 hours per day = 10 kWh per day. When calculating, you need to consider the battery’s performance and how much continuous output you require. It’s essential to consult with a solar energy professional to size the panels and batteries for your needs properly.

Are Lithium Batteries Better Than Lead Acid?

It would take several lithium-ion batteries to power a home for a day or more. Lead-acid batteries, which have been around for decades, are less efficient, offer less storage, are often larger, and do not last as long. Lithium batteries can be left at a partial charge without any adverse effects.

What Are Time of Use Home Batteries?

Having stored energy could be helpful in other applications. A handful of utilities have time-of-use (TOU) rates that make customers pay more for electricity during high-demand times. With a home battery, a homeowner could switch to stored energy during high demand periods to reduce the amount of electricity they buy from their utility and reduce the average cost per kilowatt-hour (kWh) they are charged. If you need to recharge your electric vehicle (EV) during that same high-demand time, you could use stored electricity rather than depend on expensive utility power.

But outside of California, TOU rates are not typical, although many utilities are testing TOU programs of their own. Currently, most utilities apply “net metering” rates to solar households, offering to buy their electricity at a per kilowatt charge equal to what they charge for power. For example, let’s say you sell electricity for 11 cents a kilowatt-hour (kWh) to your local utility. It’s likely in many states that the utility charges you the same rate when it sells you electricity. In this case, which is a more typical net metering situation, electricity storage offers no financial benefits.

Which Home Battery Is Right for Me?

While battery technology is still in its infancy, a breakthrough came with lithium-ion batteries. These batteries–the same kind found in cell phones and many other devices–capture energy from solar panels as direct current (DC) and convert it through an inverter to alternative current (AC), the kind used in American homes.

Several flavors of battery storage exist: DC-coupled systems, AC coupled systems, AC battery systems, and hybrid converter systems. Considering the complexity of the options, ask your battery installer which system will work best with your solar array and the infrastructure of your local utility.

Batteries can be sized to serve the size of your home and your solar arrays. A larger home may need a larger battery. Again, consult JB BATTERY energy expert and electrician to ensure the sizing works and the system will meet your expectations.

Solar Rebates and Incentives

Incentives exist for homeowners who want to invest in battery technology, often in conjunction with solar installations. A 26 percent tax credit exists for solar battery buyers, too, though to get the entire credit, the energy stored must come entirely from the sun—and the system must be in place by the end of 2020. According to EnergySage, the average solar shopper saves at least $5,000 thanks to the solar tax credit. In 2021, the tax credit drops to 22% before expiring in 2022.

As the federal government’s incentive expires, some states consider tax credits for batteries, among them California, Maryland, and Massachusetts. Keep your eye on your local state legislature as a new tax credit for solar storage may be on the way. You can use our Find Rebates tool to look for solar rebates in your area.
