典型应用
Applications
- 对比同光强下不同组件的 Pmax，判断衰减或隐裂风险
- 读取 IV/PV 曲线，定位开路、短路或异常膝点
- 结合光强—功率模型，推算 1000W/m² 下的理论功率，核对铭牌
- Compare Pmax across modules under matched irradiance
- Inspect IV/PV shapes for defects
- Extrapolate power at 1000W/m² using logged irradiance
测量项目与量程（说明书摘录）
Measurements (manual)
| Pmax | 0~800W，±0.5% — 当前光强下最大发电功率Peak power at current irradiance |
|---|---|
| Vmax | 0~60V，±0.1% |
| Imax | 0~35A，±0.1% |
| Vopen | 0~60V，±0.1% — 开路电压Open-circuit voltage |
| Ishort | 0~35A，±0.1% — 短路电流Short-circuit current |
| 内部温度Internal temp. | 0~60°C，±3% — 过温需自然冷却Cool after alarm |
安全提示：测试前确认组件极性；光传感器须与组件共面并正对太阳。整机保修一年，详见中文说明书。
Observe polarity; keep the irradiance sensor coplanar with the module. One-year warranty per manual.
