Home energy storage systems comprise battery modules, a BMS, an inverter and an energy management unit. They can work with residential solar installations to store electricity and provide home backup power. Testing considers wall-mounted or stacked construction, installation environment, rated capacity and grid-connected or off-grid operation, coordinating assessment of batteries, power conversion and complete-system protection.
Key checks cover battery charging and discharging limits, module communication, overcurrent and overtemperature protection, insulation and grounding, temperature rise and fault shutdown logic. For expandable products, the number of battery modules, compatible inverters and installation clearances must be specified to validate representative configurations and critical differences.
GTG Group develops testing plans based on the target market, product configuration and existing reports, providing document review, sample validation, issue analysis, corrective retesting and certification application support. Coordinated assessment of the complete product, critical components and system interfaces helps manufacturers define the project scope and prepare technical documentation.
Selected market access certifications for home energy storage; applicable items are confirmed against the actual configuration
| Target Market | Electrical & System Safety | Electromagnetic Compatibility | Configuration Validation | Supporting Documents |
|---|---|---|---|---|
| United States | Applicable routes such as UL confirmed by product category | Requirements such as FCC checked by equipment category | Inputs, outputs, installation and protection | Models, labels and technical documentation |
| European Union | Applicable regulations and standards confirmed by product scope | EMC assessed for the complete configuration; wireless reviewed separately | Grid connection or system interfaces checked by use | Declaration of conformity and technical documentation |
| China | Applicable requirements checked by product category | Test items confirmed by product and environment | Rated parameters and operating conditions | Marking, manuals and test documentation |
| Japan | Confirmed separately for product, power supply and battery categories | Applicable requirements checked by product scope | Input supply system and installation configuration | Local marking and technical documentation |
| South Korea | Classified by sales model and critical components | Applicable items confirmed by product category | Interfaces, ratings and protection configuration | Labels and application documents |
| Canada | Safety assessment route checked by product type | Applicable items confirmed by equipment category | Power distribution, installation and system interfaces | Technical documentation and marking |

Testing of the complete product, critical components and system interfaces against applicable standards and agreed operating conditions
| Test Category | Assessment Basis & Scope |
|---|---|
| Battery Safety | IEC 62619 and IEC 63056 are assessed according to the product scope, with testing levels defined for cells, modules and battery systems. |
| System Safety | UL 9540 is assessed for applicable North American energy storage systems. Thermal runaway propagation testing under UL 9540A is determined separately according to project conditions. |
| Power Conversion & Grid Connection | Electrical safety and grid connection tests are confirmed according to inverter topology, grid-connected and off-grid modes, and installation requirements. |
| Abnormal Conditions | Protection responses are verified under short-circuit, overload, control fault and communication fault conditions. Specific tests are determined by the applicable standards and system configuration. |
| Environment & Reliability | Environmental, mechanical and continuous-operation tests are developed according to indoor or outdoor use, installation method and product claims. |
The applicable standards editions and scope are confirmed during planning. Reference:IEC 63056、UL Energy Storage System Assessment。
