EL tester installation and maintenance considerations

- Apr 02, 2019-

The EL tester should first check whether the inverter is damaged during transportation before installation. When selecting the installation site, it should be ensured that there is no interference from any other power electronic equipment in the perimeter of the PV module of the PV module; before the electrical connection, it is necessary to cover or disconnect the PV detector panel of the PV module with opaque material. DC side circuit breaker.


The cables used in the photovoltaic system power generation system must be firmly connected, and the PV module EL detector is well insulated and of appropriate specifications. All electrical installations must meet local and national electrical standards. The inverter can be connected to the grid only after obtaining the permission of the local power department and all electrical connections are completed by the professional technician PV module EL detector.


Do not install the EL detector inverter in direct sunlight. Otherwise, the internal temperature of the inverter outside the EL detector of the PV module may be caused. The inverter will derate the internal components to protect the internal components. Even the temperature is too high, causing the inverter temperature to malfunction. The installation site should be chosen to be strong enough to support the weight of the inverter for a long time.


The selected installation site ambient temperature is -25 ° C ~ 50 ° C, the installation environment is clean; the ambient humidity does not exceed 95%, and no condensation; EL detector inverter should be left in front of the inverter enough to make easy to observe data and maintenance The installation place ensures that it will not shak
