During the annual visual examination, our O&M technicians clean the filters, carry out electrical tests and check the individual functions of the inverters according to the manufacturer's test protocol.
Once a year, the transformer is examined for leaks, e.g., due to an oil leak. In addition, the earth resistance is measured and the protection technology checked.
During an inspection, our colleagues check whether the modules display any damage. Damage can be caused by rock chips, mowing works or lightning strikes, for example. In addition, our technicians measure the power of the modules and check the module connection cables.
