What should you know about safely installing an Energy Storage System (ESS)?
Installing an Energy Storage System (ESS) is more than just connecting a battery. Whether you’re a seasoned installer or still in training, placing an ESS safely requires knowledge of the right PGS guidelines and strong collaboration. This article explains where things often go wrong and how to avoid those pitfalls.
PGS37-2: the rules before commissioning
Once an ESS is delivered to site, PGS37-2 applies. This guideline focuses on safety during storage, transport (ADR), and installation. Think of temporary fire extinguishers, safe battery storage, and coordination with the builder. Many incidents happen in this phase. These can be prevented by organizing solid temporary fire safety and leaving nothing to chance.
PGS37-1: safety during operation
Once the system is activated, PGS37-1 comes into effect. The focus then shifts to operational safety. Monitoring, fire detection, extinguishing systems, and compartmentalization must now be in place. Don’t forget about inspections, maintenance agreements, and access for emergency services.
Common mistakes during ESS installations
A frequent mistake is confusing the two PGS phases. Sometimes PGS37-1 provisions are expected during construction, or crucial PGS37-2 elements are skipped. The transition from PGS37-2 to 37-1 is not just a formality—it’s a critical step that must be well-prepared and clearly documented.
Tips for a safe installation
- Involve all stakeholders from the start, including the fire department.
- Provide temporary safety measures during construction.
- Clearly define transition points between the guidelines.
- Make the PGS switch an intentional part of your planning.
Installing an ESS is specialist work. Applying PGS37-1 and PGS37-2 correctly helps you avoid risks, disputes, and delays. Whether you’re installing a home battery or a large commercial system: safety starts with knowing the rules—and you bring them into practice.
