• Identifying the placement of the solar cell modules that make up the string
• Identifying failed solar modules, failed clusters and failed cells
• Open failure detection of bypass diode in cluster
• Identification of disconnection points for wiring between modules
• Identification of poorly conducted module connector

Identifying the placement of the solar cell modules that make up the string

(1) Connect the transmitter.

The transmitter connection point is the primary side of the string breaker in the relay terminal box.
Turn off the string breaker during exploration.
* If the breaker is ON, the signal may be supplied from the power conditioner and the receiver may not respond.

(2) Exploring with a receiver (4-point exploration)
* Exploring the bus bar.

Exploration of failed (unpowered) modules

(1) Search the bus bars at the four corners of the module, and if even one location does not respond, the module is disconnected.

(2) Search for the interconnector of the module, and if the cluster part is unresponsive, it is a disconnection in the cluster.

Exploration of failed (decreased output / heat generation) cells

(3) Trace the interconnector of the module, and if there is an unreacted part, the interconnector in the cell is broken.

Correspondence function for failure mode of solar cell module

* When the failure phenomenon of the solar cell module is a decrease in power generation output

No string output
* The series electric circuit including the module in the string is broken.

(1) Poor continuity of module connection connector or disconnection of module connection wire
(2) Damage to bypass diode in module (open) + disconnection of bus bar or disconnection of interconnector or damage to solar cell
