DC Coupled

DC Coupled Solution

A DC Coupled solution is used when you are integrating energy storage with a new PV installation. You can also retrofit an energy storage system to an existing PV array if the PV array has string inverters.

What is DC Coupled?

DC coupled solutions allow both the PV and the battery to be served by a single inverter.

In a DC coupled configuration, the battery will be directly charged by the solar panels compared to when you use an AC Coupled system and the solar power goes to PV inverter first and then to charge the battery. Thus, DC coupled solutions are more efficient and you avoid the cost of a PV inverter.
