The testing standards for ordinary smart home terminals are not applicable here. Smart terminals in new energy environments must pass the following stricter requirements:
| test project | severity level | Corresponding scene |
|---|---|---|
| Power frequency magnetic field immunity | 30 A/m for 1 minute | Communication box installed near the transformer room and inverter AC side. |
| Surge (impact) immunity | Differential mode ± 2kV, common mode ± 4kV | Photovoltaic array DC cable coupled with lightning induced waves. |
| Electrostatic discharge immunity | Contact discharge ± 8kV, air discharge ± 15kV | When the operation and maintenance personnel touch the RS485 interface or screen. |
| High Acceleration Life Test (HALT) | -40 ℃~120 ℃ rapid temperature change random vibration | Expose PCB solder joint cracks and crystal oscillator stop defects in advance. |
This is the maximum detection increment that distinguishes intelligent terminals from traditional electrical equipment. According to GB/T 39786 (Network Security Protection of Power Monitoring Systems) and IEC 62443-4-2:
| test item | test method | Judgment requirements |
|---|---|---|
| Identity authentication strength | Violent cracking tool attempts to log in | Prohibit the use of hard coded default passwords (admin/admin), with a failure lock time of ≥ 5 minutes. |
| Communication integrity | Intermediary tampering with meter readings or power commands | TLS 1.2 or above encryption, or the national security SM2/SM4 algorithm, must be enabled. |
| Firmware reverse protection | Read Flash storage chip | The firmware must be signed and verified, and the JTAG/SWD debugging interface must be physically disabled or fuse locked. |
| Remote Upgrade (OTA) Security | Simulate issuing incorrect signatures or low-level firmware | Reject downgrade attacks, enter security recovery mode after verification failure. |
| product form | Domestic market access requirements | International market access requirements |
|---|---|---|
| Photovoltaic module level shutdown/optimizer | CQC Mark (GB/T 37410) Electromagnetic Compatibility | UL 1741 PCS (North American rapid shutdown), EN 62109 (EU safety regulations) |
| Energy storage battery BMS control | CQC logo (GB/T 34131) | UL 60730 (North America) IEC 60730 |
| Ordered charging station controller | CCC certification (including telecommunications terminal functions) | CE-RED (European Union Radio Directive) |
| Energy industry gateway (edge computing) | Testing of DL/T 634.5101/5104 protocol by Electric Power Research Institute | FCC Part 15B IEC 61850-10 Interoperability Test |
State Grid/Southern Power Grid Enterprise Standard Upgrade: Intelligent fusion terminals connected to the distribution network are required to pass GB/T 28181 (Video Surveillance Security) or GB 35114 detection to prevent intrusion into the power grid dispatch system through camera ports.
EU RED Network Security Authorization Act: Starting from August 2025, smart terminals with wireless functionality exported to Europe must be accompanied by a Network Resilience Act (CRA) compliance statement for CE certification.
