With LSI fault location set from Solartektor, the solar installer can determine which module is defective, whether there are defective areas within the module, whether there are blown bypass diodes, where there is an insulation fault or exactly where burnt-out plugs are located. The LSI consists of three device groups with which the technician can work on three focal points: With the laser detector set he creates a module or string diagram, with the signal detector set he finds cable breaks such as burnt DC connectors or bitten-through cables (rodent damage) in the DC line and with the isotector he finds insulation faults.

With the solar detector set, the solar technician can actually locate cell damage in the module if this causes a large loss of power. This is because the cells then convert the sunlight into electricity only poorly or not at all. The laser beam of the projector modulates a pulsed signal onto the modules. The energy of the signal is transmitted via the string line to the laser detector on the inverter. (mfo)
