Introduced in the 2017 NEC, Article 706 was created to centralize the rules for the growing number of ESS installations, from a solar powered generator for home to large commercial battery banks.
This brief provides further clarification and resources to assist with designing, constructing, and installing these type of systems and/or system components and verifying that they are safe and meet code.
Accordingly, energy storage systems, including the final placement, positioning and securement of batteries, capacitors, and kinetic energy devices (e.g., flywheels and compressed air) and all
In this article, I''ll highlight some of the changes and discuss their impacts on PV, energy storage systems (ESSs), and interconnected power systems in Articles 690, 706, and 705, respectively.
All nonresidential buildings with solar PV systems are required to have a battery energy storage system unless they meet an exception. For more on the requirements for battery energy storage systems,

This technical bulletin provides an update on solar and storage installation compliance requirements in Part 6, California Energy Code, as well as CSU-specific reporting requirements.
Article 705 contains additional requirements for grid-tied photovoltaic systems, while Article 706 addresses energy storage systems in general, which applies to photovoltaic systems that
The National Electric Code (NEC), published by the National Fire Protection Association (NFPA) and officially designated as NFPA 70, sets the standards for electrical safety and

Empa Solar Energy Europe is a leading energy storage equipment manufacturer and integrator based in Poland, serving the European market. We specialize in C&I energy storage systems for factories and warehouses, industrial battery storage systems for heavy-duty applications, factory energy storage systems (ESS) to optimize production, commercial battery energy storage systems (BESS) for retail and offices, enterprise storage solutions for corporate campuses, industrial park energy storage for multi-tenant sites, commercial battery storage for peak shaving, industrial battery storage systems for backup power, and remote base station power solutions for telecom towers. Our portfolio also includes lithium-ion batteries, system-level battery management systems (BMS), energy conversion systems (PCS), energy storage battery system cabinets, communication cabinets for telecom and data centres, integrated PV-storage systems, distributed energy resources, deep discharge battery technology, and containerised BESS. As a full-service provider, we also offer modular battery racks, backup emergency power, and zero‑carbon microgrids. Our advanced lithium‑ion and sodium‑ion solutions ensure safety, scalability, and high performance for commercial, industrial, and utility projects across Europe.
Our modular energy storage portfolio ranges from compact lithium-ion batteries to 20ft/40ft mobile containers and outdoor all-in-one storage cabinets with IP54 protection. We are a leading energy storage equipment manufacturer, offering communication cabinets for 5G/telecom, server racks for data centers, and IP54 rated enclosures for harsh environments. Our stackable design allows flexible capacity expansion, while our grid-forming technology ensures stable off‑grid operation. Whether for remote base stations, off‑grid power systems, backup emergency power, integrated PV-storage or large zero‑carbon parks, our products feature advanced thermal management, deep discharge cycling, and compliance with European and international standards. We also provide professional energy storage system installation and after‑sales support across Europe.
