Residential energy storage​

Helping home owners secure their energy independence

Residential energy storage

Residential energy storage is a crucial component to improving energy resilience for homeowners. Natural disasters, and the increasing frequency of grid failures leave residents without power and feeling vulnerable. When combined with renewables and/or used for backup power and demand response, home owners can secure their own energy independence and reduce their energy costs.

POWERSYNC’s integrated systems are designed to be long lasting and can be easily matched with advanced energy management controls software to maximize your energy savings for your home. Take complete control of your home with energy automation allowing you to remotely control and prioritize equipment and appliances while improving your disaster readiness.

Our efficient LiFePO4 Modular Storage options can be deployed with a wide range of industry standard inverters and energy management systems. The Carbon Nanotube VRLA/AGM offers a more economically and simplified choice while competing with most lithium systems on price and performance.

Our integrated systems protect the home by:

Storing excess electricity generated from renewables during the day so it can be used at night.

Saving money by connecting to the utility grid and storing surplus energy during off peak hours to use when the utility electrical rates are higher.

Taking advantage of utility demand response / energy buyback programs.

Having your own backup power (UPS) that can be used in the event of grid instability or failure.

    Renewable Energy

    Use renewables plus energy storage to create your own home power plant. POWERSYNC solutions are flexible, can be installed with any solar or wind generator and easily connected to new or existing systems.

    Energy storage unlocks the true value from investments in renewable energy by maximizing your return on your investment by helping to lower or eliminate energy bills.

    Critical Power

    Protect your family and home with a residential uninterruptible power supply (UPS) in the event of grid instability or failure. During a grid failure POWERSYNC energy storage will run your most critical equipment and appliances.

    Energy resiliency means having the power when you need it most and not depending on the gird.

    Peak Shaving

    Lower your electrical bills by installing an energy storage system for peak demand shaving. POWERSYNC storage will help you avoid unwelcomed peak utility fees by allowing you to pull short-term demand spikes from your energy storage rather than the grid.

    Enhance your home with an energy storage system to lower your costs, improve your energy resilience, and gain control over your own energy use.

    Demand Response

    Utility companies are looking for ways to make their grid more reliable during peak hours. Incentives are in place to encourage residential customers to install POWERSYNC energy storage which can be used when demand response events are triggered.

    Utility companies will pay home owners with residential energy storage systems who grant access to their energy during grid demand spikes.

    Featured Install: Off-Grid System in Malibu, California

    In 2015 Rick Fields purchased his (and everyone’s) dream home on a mountain top overlooking the Pacific Ocean in Malibu. One of the unique attributes about this home was that it was completely off-grid with no pipes or wires coming to the property. The nearest power lines are about a mile away. It would cost more than $300,000 dollars to get his home connected to the power grid.
