VERIFICADOR DE POTENCIA FOTOVOLTAICA LR8400-92/-93
Check Your Solar Power Levels and Verify Integrity to Solve Power Loss Problems
Interrumpido
Hioki Memory HiLoggers are high-speed data loggers for recording multiple chanels of voltage, current, temperature or humidity signals, providing complete isolation between channels and strong noise resistance. The LR8400-9X Series take logging to a new level by meeting applications in solar power measurement.
Vídeo del producto
- Estimate expected electricity production (estimated electrical energy) (*1)
- Production can be measured without shutting off the circuit
- Investigate module failures by identifying strings with wiring breaks and using the instrument in conjunction with a masking shield
- Measure production trend
- Add up to 7 more channels of clamp or temperature measurements even in PV mode (*2)
- *1:Estimate the expected electricity production at the current time under continuously varying conditions of air temperature and insolation. Compare the estimate with actual electricity production.
- *2:When PV mode is turned OFF, the instrument can also be used as a 30-channel data logger. When PV mode is turned OFF, optional input units can be added to expand the instrument to a maximum of 60 channels.
