What are the key codes for solar PV & battery storage?

This article highlights the key codes and some of the top sections contractors working with solar PV and battery storage should be familiar with. The most common code system designers, installers, and inspectors refer to for PV and ESS systems are NFPA 70, or the National Electrical Code (NEC).

What are the requirements for a stationary battery ventilation system?

Ventilation systems for stationary batteries must address human health and safety, fire safety, equipment reliability and safety, as well as human comfort. The ventilation system must prevent the accumulation of hydrogen pockets greater than 1% concentration.

What standards are used in a battery room?

Common standards in the battery room include those from American Society of Testing Materials (ASTM) and Institute of Electrical and Electronic Engineers (IEEE). Model codes are standards developed by committees with the intent to be adopted by states and local jurisdictions.

What are the requirements for a lead-acid battery ventilation system?

The ventilation system must prevent the accumulation of hydrogen pockets greater than 1% concentration. Flooded lead-acid batteries must be provided with a dedicated ventilation system that exhausts outdoors and prevents circulation of air in other parts of the building.

What are the safety requirements related to batteries & Battery rooms?

Employers must consider exposure to these hazards when developing safe work practices and selecting personal protective equipment (PPE). That is where Article 320, Safety Requirements Related to Batteries and Battery Rooms comes in.
