PV Power Verifier LR8400-92 includes 200A AC/DC sensor and other bundled accessories. It verifies the correct power level to solve power loss problems. The device enables to estimate expected electricity production (estimated electrical energy), expected electricity production at the current time at fluctuating conditions of air temperature and insulation and compares the estimate with actual electricity production. Even without shutting off the circuit the production can be measured.
The device also measures the production trend, investigates module failure by identifying strings with wiring breaks and using of instrument with a masking shield. Even in PVC mode, 7 more channels of clamp or temperature measurements can be added. The instrument can be used as a 30-channel data logger even when PV mode is turned OFF. When PV mode is turned OFF, the device can be expanded by adding optional input units.
