What are the warranties?
The battery system comes with a 10-year manufacturer’s warranty. Additionally, HDM (the current owner of the system) is contractually obligated to provide a warranty for the first 6 years. After this period, system ownership will be transferred to the homeowner, along with the remaining manufacturer’s warranty.
How long does it take to get my batteries?
Receiving approval for the medical baseline rate can take up to a month, and securing SGIP funds approval may require an additional 2-4 months. Once these funds are approved, projects will be permitted and installation will be scheduled on a first-come, first-served basis. Due to high demand, and the length of time to receive the rebate reservation, we cannot guarantee a specific timeline for installation. Batteries will be shipped directly to the home 3-5 days before installation.
How will batteries save me money?
Batteries can save you money through time-of-use (TOU) arbitrage by storing electricity when rates are low and using it when rates are high. Typically, utility companies charge more for electricity during peak demand hours, usually in the late afternoon and early evening. By charging your battery system during off-peak hours when electricity is cheaper, and discharging it during peak hours, you can avoid paying higher rates. This strategy not only reduces your electricity bill but also enhances energy efficiency and can provide backup power during outages.
Do I need solar to have batteries?
No, you don’t need solar panels to install a battery energy storage system at your home or business, as batteries can be charged using electricity from the grid to provide backup power, enhance energy management, and participate in time-of-use arbitrage independently of solar power; however, pairing batteries with solar panels can maximize savings and efficiency by storing excess solar energy for later use, especially during peak pricing times or when the sun isn’t shining.
Can I connect my batteries to solar?
Yes, it is possible to connect batteries to your existing solar system, but our company does not offer this service to avoid voiding warranties on your current installation; connecting batteries can optimize energy usage by charging from the grid during off-peak hours when rates are lowest and solar production is minimal, helping you maximize savings and manage consumption, while additional solar panels—whether on-grid or off-grid—can also be added later to charge the batteries directly without affecting NEM status.
What is the difference between full home and partial home backup?
A full home backup system powers all the electrical circuits in your home, ensuring that everything from lights and appliances to HVAC systems continues to operate as usual, provided the battery capacity is sufficient. In contrast, a partial home backup system is designed to supply power only to essential circuits or appliances, such as refrigerators, key lights, and necessary medical devices. The choice between the two depends on your specific power needs during an outage and your budget constraints. Homes must have a peak demand of 12 kWh or more to qualify for a 100% subsidized full home backup, while homes with lower demand may only qualify for a partial home backup.
What happens when the power goes out?
When the power goes out, a battery energy storage system can automatically take over to provide power to your home or business. If the battery is charged, it will begin supplying electricity to designated circuits or the entire property, depending on how the system is configured. This seamless transition keeps your essential appliances running without interruption during a power outage. The duration for which the battery can supply power depends on its capacity and the amount of energy being used. For households with solar panels connected directly to the battery, the battery can continue to be charged during the day, extending the backup power duration as long as the outage continues and sunlight is available.
What is the difference between LiFePO4 and Lithium Ion Batteries?
Lithium iron phosphate (LiFePO4) batteries are often considered superior to standard lithium-ion batteries for several reasons. LiFePO4 batteries offer enhanced safety due to their stable chemical composition, which significantly reduces the risk of fire or explosion. They also boast a longer lifespan, enduring more charge and discharge cycles with minimal capacity loss. While lithium ion batteries may provide higher energy density, making them suitable for compact devices needing high power, LiFePO4 batteries are preferable where safety and durability are prioritized, such as in residential energy storage or electric vehicles. Additionally, LiFePO4 batteries perform better across a wider range of temperatures, further solidifying their advantage.
What is included with the installation of my batteries?
Every battery storage installation is comprised of several key components: batteries, an inverter, a sub-panel, and conduit. We typically install the batteries either in the garage or externally, depending on the layout and specific conditions of your property. For optimal installation, we prefer to place the sub-panel adjacent to the main panel, with the batteries and inverter mounted on the same wall. However, each installation is unique, and we must adhere to the specific regulations and guidelines set by the local AHJ, which can vary.
How do I control the batteries?
You can control your battery system using a dedicated app, which allows you to monitor and manage the system remotely from your smartphone or tablet. This app provides real-time insights into your battery’s performance and enables you to adjust settings according to your energy needs. Additionally, we program the battery initially to ensure it operates at optimal efficiency for savings. This programming takes into account peak energy rates and your typical usage patterns to maximize cost-effectiveness while providing the flexibility to adjust settings as your needs change.
Do I own my batteries?
To fully finance your battery project, the 30% federal tax credit on its fair market value can be utilized. For the tax credit to be claimed, the project must be owned by the same entity for five years, meaning that for the initial six years, the battery system will be under third-party ownership. During this period, the homeowner will not be responsible for any payments, liens, or obligations, and will retain control over the battery. Ownership will transfer to the homeowner in the sixth year. Additionally, the battery will be covered by an extended guarantee for the first six years, during which the third-party owner will maintain it and address any issues that may arise.
