Solar Battery Backup Systems
Solar battery backup guarantees a power source — even during a grid service failure or natural disaster. When the grid goes down, a solar battery backup system automatically detects and transitions your solar system from grid power to backup power. Protect your home from outages with our solar battery backup kits.

Why install a solar system with battery?
Protect Against Outages
Solar battery kits give you everything you need to power your home and keep it running during a grid outage.
When utility power is available, your solar panels generate electricity that can roll back your energy bill. If the power goes out, the system draws energy from the battery bank to keep your most important electrical loads running.
If you live in a harsh climate or your local power grid is unreliable, grid-tie solar batteries can provide peace of mind and help you live life uninterrupted by outages.
Reduce your utility bill
The benefits of having a solar battery kit extends beyond power backup. Solar battery systems efficiently store excess energy generated by your solar panels, allowing you to tap into this resource during peak hours when utility rates are at their highest.
By strategically harnessing stored energy, you effectively reduce your utility bills, making solar battery kits a wise investment for every solar owner seeking substantial financial advantages.
Energy Independence
Purchasing a battery along with your solar kit offers a pathway to energy independence from your utility company, especially when they provide a meager buyback rate for surplus energy you send to the grid. With a battery storage system in place, excess solar energy can be stored instead of sold to the utility for low rates. This empowers you to rely less on the utility's low buyback rate and instead harness your self-generated energy, reducing your reliance on your utility company.
What’s the right battery size for you?
Partial Backup
10k20kWh Storage
A 10 kWh storage capacity offers typical homeowners partial home backup, enabling you to run essential appliances and daily-used electronics such as refrigerator, computer, and TV. While these partial backup systems efficiently manage most of life's conveniences, non-essential loads like hot tubs, EV chargers, or air conditioners are temporarily shed during power outages.
Whole-Home Backup
20-40+ kWh Storage
In addition to the above, a 20-40 kWh storage system would account for larger energy-intensive loads like your well pump, air conditioning, laundry, and dishwasher. Look for a battery bank in this size range if you need whole home backup for a single-family home.
What is the difference between AC and DC Coupled?
AC (alternating current) and DC (direct current) coupled solar and storage systems are two distinct configurations for integrating solar panels with energy storage solutions.
In an AC-coupled system, the solar panels and the energy storage are connected to the AC side of the inverter. This setup allows for greater flexibility in the choice of solar panels and battery storage, as they can be installed independently and easily replaced or upgraded. Additionally, AC-coupled systems are well-suited for retrofitting existing solar installations with energy storage capabilities.
On the other hand, DC-coupled systems involve connecting the solar panels directly to the DC side of the battery inverter. In this setup, the solar panels' DC output is directly used for charging the batteries, which can result in slightly higher efficiency due to fewer conversion losses. DC-coupled systems are often preferred in scenarios where maximum energy capture and efficiency are crucial.
The choice between AC and DC-coupled solar and storage systems depends on the specific needs and goals of the installation. AC-coupled systems offer greater flexibility and are ideal for retrofitting or when the solar and storage components come from different manufacturers. DC-coupled systems, on the other hand, may be favored when efficiency and direct utilization of solar energy are critical considerations.
Understanding the advantages and limitations of each configuration helps in making the most appropriate choice for a particular solar and storage project.
| AC Coupled | DC Coupled |
|---|---|
|
Integrates into existing systems AC-coupled solar and storage systems are better suited for micro inverter setups or for integrating energy storage into existing solar installations. The flexibility of AC coupling allows easy addition of energy storage to an already installed micro inverter system without major modifications. |
Cost-effective DC-coupled systems can be more cost-effective, particularly in new installations. Since the solar panels and batteries share the same inverter, fewer components are needed, resulting in reduced installation and equipment costs. |
|
Reliable AC-coupled solar and storage systems are known for their reliability, contributing to their popularity in various applications. One key advantage of AC coupling is the ability to operate solar panels and energy storage components independently. In the event of a battery malfunction or failure, the solar panels can continue generating electricity, providing a reliable power source to the grid. |
Battery charging In DC-coupled systems, solar panels directly charge the batteries at the same voltage level, allowing for optimized charging and management of battery states. This setup can enhance the battery's lifespan and performance by precisely controlling the charging process, reducing the risk of overcharging or undercharging. |
|
Less efficient AC-coupled solar and storage systems can be less efficient due to additional energy conversions, which introduce conversion losses. |
More efficient DC coupled solutions are more efficient, as there is less energy loss in converting DC to AC energy to power your system. |
