SunFusion UES vs. Tesla Powerwall

Are you considering a Tesla Powerwall system for your home?

If so, you realize the benefits that a system like that can bring. Having the ability to power your entire home on battery provides distinct benefits:

• Immunity from power outages and brownouts.

• Save money on monthly energy bills by charging batteries using solar or off-peak grid power.

• Keep your home running when utility companies shut off the power to your neighborhood.

Many Tesla Powerwall owners call us because their Tesla system can’t handle the large energy loads they need. The Powerwall can only produce 5kW of continuous power output. That’s hardly enough to power a modern home.

When considering a UES system for your home, there are two essential factors: Storage Capacity and Maximum Power Output.

A larger battery storage capacity lets you keep your appliances running longer. The maximum power output of a system regulates how many appliances you can run at the same time.

A UES system from SunFusion can power all of your home appliances uninterrupted!

• Microwaves

• Refrigerators

• Air Conditioning

• Televisions

• Toaster Ovens

• Coffee Maker

• Pool Pump

• Electric Gates

• Electric Vehicle Chargers

• No solar installation needed

• Just about any other large-draw appliance!

SunFusion custom builds each UES system to meet your specific household needs. We can offer custom systems with extremely high battery capacities and power outputs to handle even the heaviest loads!

We’re confident you won’t find a better product anywhere else. See how we stack up to the Tesla Powerwall and others:

Have Questions?

We’re here to help! We know that the topic of sustainable energy storage is somewhat complicated. Here are some of the most frequently asked questions we hear from prospective customers.

How Does it Work?

Our overview video explains how UES systems work to power your home when you lose utility power:

What advantages do I gain from energy storage?

• Federal and State Incentives. Through 2024, battery storage is eligible for the federal 30 per cent Investment Tax Credit, encouraging companies to develop long-term investments that drive competition and technological innovation, lowering consumer costs. While the credit for commercial and utility drops to 10 per cent and stays at that rate permanently.

• Financial Savings. San Diego Gas & Electric, the IOU that serves San Diego County, has a history of raising its regular rates and will continue to do so for the foreseeable future. Meanwhile, SDG&E buys energy from solar customers when they produce an excess. The utility also sells it back to them when their arrays are not producing. However, a proposal pending approval from the CPUC to change the length of the buying and selling periods, known as Time of Use (TOU), basically amounts to a rate increase. Installing a UES battery system would take you out of the rate-hike equation.

• Leaving the Grid Behind. To meet the state’s sustainable energy standard that calls for 100 per cent renewable power by 2045, SDG&E is building new infrastructure. Yet, such development will not be paid for out of company profits, and it will be paid for out of rate-payers pockets. SDG&E, a Sempra utility, reported fourth-quarter 2016 earnings of $151 million, up from $144 million in the same quarter of 2015.

• Solar-Plus-Battery Storage Increases Property Values. Adding rooftop or ground-mount solar arrays and battery storage is an immediate financial reward. But they also increase the value of your home or commercial building should you decide to sell, according to real estate agents and appraisers.
  

What makes SunFusion Energy Systems the best choice?

• SunFusion systems are designed to accommodate any residential or commercial load. Our battery lineup includes the 14-600 kWh Echo Outdoor.

• Our batteries are comprise fifth-generation lithium iron phosphate (LiFePO4) with prismatic cell technology and are rated for a 16,000-cycle lifespan of 49.5 years. Unlike cylindrical battery packs with hundreds of cells, our single-cell packs are designed for constant use and have a high heat resistance of up to 576 degrees, making them incredibly safe. They are the most advanced batteries on the market today.

• We are the only UES provider that includes a rapid shutdown switch in each of our systems, allowing the unit to be completely shut down in an emergency quickly.

• We make the only whole-house, whole-building systems now available, meaning they’ll pick up all your heavy-hitting loads, including air-conditioning, pool pumps and electric vehicle chargers, while providing ample output for other appliances and needs. We keep the lights on 24/7, 365 days a year!

• We offer an industry-leading 25-year, no-prorated warranty.
