FAQs 6

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 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.

What is the best battery for a retrofit installation?

The best battery for your retrofit installation really comes down to your unique needs and reasons for installing an energy storage system. A single 10 kWh battery can serve multiple purposes, from providing backup power during outages to helping homeowners avoid costly demand charges.

Do storage systems qualify for tax incentives?

For information on the tax incentives available to storage systems see our previous article HERE. Relevant to the discussion of a retrofit, a storage system installed in conjunction with an existing PV system can qualify for the 30% ITC if charging is performed by the solar system.

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.

What is a DC-coupled retrofit?

A DC-coupled retrofit involves replacing your existing inverter with a hybrid inverter that works with both solar panels and batteries. The biggest benefit of a DC-coupled system is the improved efficiency. However, it’ll cost you.
