Direct current (DC) electricity is what solar panels produce and what batteries hold in storage while alternating current (AC) electricity is the type used on the grid and in most household devices. A device called an inverter is required to convert the DC electricity from solar panels into appliance-friendly AC.
Article 706.2 of the 2017 National Electrical Code (NEC) defines an energy storage system as: “ One or more components assembled together capable of storing energy for use at a future time. ESS (s) can include but is not limited to batteries, capacitors, and kinetic energy devices (e.g., flywheels and compressed air).
As mentioned above, PV modules will produce dc power. That power must be converted to ac to be used in most commercial and residential applications. In contrast, battery cells must be charged with dc and will output dc power. The ac-dc distinction has major system design implications.
The ac-dc distinction has major system design implications. In an ac-coupled system, power from the PV modules is converted to ac prior to connecting to the ESS. In other words, the output from the PV modules is fed through an interactive inverter before it reaches the ESS.
