DC-coupled systems typically use solar charge controllers, or regulators, to charge the battery from the solar panels, along with a battery inverter to convert the electricity flow to AC. DC-coupled battery energy storage system. Source: RatedPower
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.
Higher efficiency: Unlike AC systems which convert the current multiple times, DC BESSs only convert the current once, reducing energy losses and making them more efficient. Oversizing: DC-coupled systems allow solar panels to generate more electricity than the inverter rating.
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.
Oversizing: DC-coupled systems allow solar panels to generate more electricity than the inverter rating. The excess energy can be used to charge the battery, an EV charger or a water heating system, whereas in an AC-coupled system the energy is lost.
