组串级的精密辐照度测量。
Measures global irradiance (W/m²) directly at string level. The pyranometer connects via RS485 directly to the Gateway — or to the DC line via MC4 connectors, transmitting to the String Reader through our patented PLC communication over the existing DC cables. Irradiance measured at the string, not at a distant weather station, gives the most accurate local reference. Essential for TrueSTC calculations, Performance Ratio validation, and precise correlation between conditions and module performance.
单块组件上的五点温度分布测量。
Five Class A PT100 temperature sensors bonded to five measurement points across the backsheet of one reference module. Temperature is not uniform — cell temperature can vary significantly between center and edges, between shaded and unshaded areas. Five measurement points reveal the full thermal profile. The five sensors communicate via RS485, with a connector to Modbus — or from there onto the DC line via MC4 connectors, transmitting through our patented PLC communication over the existing DC cables. Critical for accurate TrueSTC calibration and for detecting thermal anomalies single-point sensors would miss entirely.
干净的 PLC 信号。即便在集中式逆变器电站中。
一块数字信号处理板，插入每台 String Reader 内置的专用插槽。它把逆变器开关噪声从 PLC 信号中滤除——在配备大型集中式逆变器、电气干扰会削弱 PLC 通信可靠性的电站中尤为必要。常规组串逆变器项目无需使用。每台 String Reader 出厂即带 DSP 插槽——板卡为选配件，需单独订购。
夹装式 PLC 拾取。无需打开电缆。
一款用于光伏组串电缆的夹装式数据拾取器。String Claw 在逆变器旁卡在组串电缆上，读取通过光伏电缆传输的组件级数据——组件电压与组件温度——无需打开或断开任何连接。它直接插入 X-String Reader 的 USB 端口：夹上、插好、完成。组串电流不由夹钳测量；电流数据取自逆变器，并在 Gateway 中与组件数据合并。
