Co-located systems can either be AC coupled, where the storage and solar PV are physically sited in the same location, but do not share an inverter; or it can be DC coupled, where solar PV and storage are coupled on the DC side of a shared bi-directional inverter. The cost savings from sharing the balance of plant costs are substantial.

It allows for time-shifting power, charging from solar, providing grid support, and exporting power back to the grid. When an ESS system is able to produce more power than it can use and store, it can sell the surplus to the grid; and when it has insufficient energy or power, it automatically buys it from the grid.
