AC-coupled home energy storage system can turn any new or existing solar system into a battery-ready system unlike alternate DC coupled / hybrid inverter solutions. With the introduction of new higher voltage batteries, AC-coupled storage has become a lower cost option to add battery storage to a solar system compared to hybrid inverters or low voltage battery storage. AC-coupling also offers a number of advantages such as flexibility for installation and also future upgrades or changes to either the solar or storage system. This means the system is better able to meet the individual needs of your home and can allow you to add battery storage at a lower cost. AC-coupled storage also allows you to better increase your independence from the grid saving further on electricity supply charges. This financial benefit is also increased through a more efficient operation. And with a simplified means to blackout-proof your home, AC-coupled storage with high voltage batteries is the smart solution if you want to add battery storage to your solar system.

What is AC-Coupled Storage?

AC coupled storage is the connection of a battery energy storage system to a solar system via AC (alternating current) electricity. Energy from a solar system is generated in the form of DC (direct current) electricity which is then turned into AC by the solar inverter. A battery inverter connected to the same electrical network via AC then converts any spare energy not used by the home back into DC so it can be stored in a battery. By contrast DC coupled storage uses what is commonly referred to as a hybrid inverter, where both the solar and battery are connected to the same inverter.

Flexibility of Installation Location

AC-coupled storage provides a greater degree of flexibility, and potentially at lower cost. When adding batteries to a new or existing solar system, one main advantage of AC-coupled storage can be the flexibility of where the battery system is installed. Many solar systems have the inverter installed either on an external wall or perhaps in a sealed services room. These might not be the best or even suitable locations for the installation of the battery system. AC-coupled storage means the battery system can be installed wherever it is best to be installed (e.g. hidden in a garage, etc), and independent of the solar system. This can also be helpful for keeping the cost of installation to a minimum.

Simplified and Improved Blackout Operation

Although modern power grids rarely experience blackouts, one of the drivers you may have when purchasing a battery system is to “blackout-proof” your home (also referred to as backup). This would mean installing and setting up your system so it is able to disconnect from the grid and continue operating. Especially for existing solar systems, AC-coupled storage offers a greatly simplified means of achieving backup. For additional cost and by adding some simple changeover switches which then interface to the AC-coupled battery inverter, your home energy storage system can connect to your rooftop solar system and provide backup power to your home.

When an AC-coupled battery is added to a home with existing solar, the original solar system usually remains unchanged and continues to operate as it does today. Your existing solar inverter still converts DC power from the panels into AC power for use in the home. The new battery system connects on the AC side of the switchboard, alongside other household circuits, rather than directly to the solar panels. This makes AC coupling particularly suitable for retrofits, because it avoids replacing or reconfiguring the existing solar inverter.

During the day, solar energy is first used by household loads as normal. Any excess solar that would otherwise be exported to the grid is detected by the battery inverter via a meter or CTs and can then be diverted to charge the battery. This process involves an extra conversion step, from DC to AC at the solar inverter, then back to DC inside the battery. While this introduces a small efficiency loss compared to DC-coupled systems, it is usually outweighed by the simplicity and lower disruption of keeping the existing solar system intact.

At night or during periods of low solar production, the battery discharges AC power back into the home to reduce grid imports. Importantly, most AC-coupled batteries can also charge from the grid if configured to do so, for example during off-peak periods. Overall, installing an AC-coupled battery allows existing solar to keep operating independently, while adding storage capability that works alongside it rather than replacing it.

With Sigen EV AC Charger, you can confidently use solar energy to power your electric vehicle. Use the fast home EV charging to optimize energy savings, embrace green technology, and enjoy a smarter charging experience.
