6 FAQs about [Retrofitting solar energy storage system]

What is an AC-coupled solar retrofit?

An AC-coupled retrofit involves installing a separate inverter for your battery, allowing you to keep your existing solar inverter. Without the need to redesign or rewire your solar panel system, this option is typically more affordable upfront.

Can a PV inverter retrofit an AC coupled storage system?

Whatever the case, to retrofit an AC coupled storage system, the PV inverter must be installed such that it is isolated from the grid during an outage by the battery based inverter. To do so, a critical loads panel is added to the facility where the PV inverter is interconnected.

How do I retrofit an AC coupled storage system?

In some instances the point of interconnection is on a subpanel or a load-side connection of the service conductors. Whatever the case, to retrofit an AC coupled storage system, the PV inverter must be installed such that it is isolated from the grid during an outage by the battery based inverter.

Can a retrofitted AC coupled storage system operate in grid backup mode?

If the retrofitted AC coupled storage system is to be operational in a grid backup mode, it is important to ensure the PV inverter and battery inverter communicate effectively. If they do not, the PV system could overcharge the batteries during a grid outage when local loads are minimal.

Can you add battery storage to a solar panel?

The good news is that it’s entirely possible to add battery storage to an existing solar panel setup. So-called “storage ready” systems are already equipped with an inverter that can easily direct excess power into a battery. But even if your system wasn’t designed with storage in mind, you still have options.

How much does a battery retrofit cost?

How much does a retrofit battery installation cost? On average, the cost of installing a battery storage system is around $9,000 after federal tax credits. However, the final price will vary based on the brand of battery and your location.
