6 FAQs about [Requirements for adding energy storage to photovoltaics]

Do solar systems need polarity & energy storage regulations?

According to NEC Article 690, solar photovoltaic systems must align with the correct PV output polarity to link with energy storage systems and follow rules for a rapid shutdown. Designers need to pay close attention to these regulations, particularly regarding their systems' energy storage.

What are the requirements for large PV power plants?

Large PV power plants (i.e., greater than 20 MW at the utility interconnection) that provide power into the bulk power system must comply with standards related to reliability and adequacy promulgated by authorities such as NERC and the Federal Energy Regulatory Commission (FERC).

How has NEC changed photovoltaic systems?

NEC regulations have had a significant impact on photovoltaic systems, particularly due to advancements in lithium-ion energy storage systems. Designers of solar systems must adapt to these changes and new conditions, which has led to a constant need for industry professionals to update their knowledge.

Do you follow NEC 690 if a photovoltaic process fuels an energy storage system?

If a photovoltaic process fuels an energy storage system, then you must follow NEC 690, specifically the eighth part. This part covers charge control, battery storage replacement, disconnects, and overcurrent security.

Which inverter is required for a combined PV and storage system?

Combined PV and storage system topologies will generally require a bi-directional inverter, either as the primary inverter solution (DC-coupled) or in addition to the unidirectional PV inverters (AC-coupled).

Why is energy availability important in assessing PV systems?

Both energy and availability are necessary metrics for assessing PV systems. If the stakeholders involved in a contract are most interested in energy production, and if the contract holds parties responsible for energy production, then it is crucial that energy losses associated with unavailability and system performance are accounted for.
