All-in-one solar and storage units integrate solar input, battery charging and discharging, inverter output and system control in a single device; some models also include battery modules. Testing starts with system topology to define power ports, energy flows, isolation methods and operating modes.
Key checks verify protection coordination among solar, mains and battery sources, covering grid-connected, off-grid, charging, discharging and transfer operations. Models with built-in batteries also require checks of thermal management, fault isolation and maintenance accessibility. Representative conditions for parallel operation of multiple units are confirmed separately.
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.

Testing of the complete product, critical components and system interfaces against applicable standards and agreed operating conditions
| Test Category | Assessment Basis & Scope |
|---|---|
| Solar Power Conversion Safety | The solar power conversion section is assessed with reference to IEC 62109-1 within its applicable scope. |
| Power Electronics Safety | Power conversion safety requirements such as IEC 62477-1 are assessed according to product standards and topology. |
| Battery & System | Configurations containing batteries require assessment of batteries and system interfaces. Grid connection validation is confirmed according to the installation location and operating modes. |
| 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 62109-1、IEC 62477-1。
