FIMER R SERIES PHOTOVOLTAIC INVERTERS: DEDICATED TESTING SYSTEM FOR POWER STACKS

In the process of repairing a photovoltaic inverter, testing is, without a doubt, the most important moment; it is at this stage, in fact, that both the effectiveness and reliability of the workmanship performed are found. For this reason, we decided to invest significant resources in the realization of what we now like to call AD/DC Ring Test, i.e., a test area consisting of centralized photovoltaic...

10 TIPS FOR PREVENTIVE MAINTENANCE OF PHOTOVOLTAIC INVERTERS

An old postulate in the maintenance world states, “servicing a train that is stationary in a depot at night is easier than repairing a broken-down train on an isolated railroad track during rush hour.” The concept is simple: having a planned preventive maintenance program and moving from reactive to proactive logic is the key to minimizing downtime (and costs) often caused by unexpected...

FV INVERTER: CIRCULAR INVERTER STRATEGY

According toa recent report published by Mackenzie, in Europe alone (the most mature PV market), there are about 16 GW of PV systems that have already exceeded 10 years of operation since their first installation. The vast majority of these systems, as widely expected, are beginning to “limp along” due to the age of their main components: modules and inverters. Unexpected failures multiply,...

THE ESSENTIAL IS INVISIBLE TO THE EYES.

After 10-12 years of operation, photovoltaic inverters need a “refresh.” By now it is well known. What is less clear, however, is what should be done to restore them to their original performance standard. Many people think it is enough to replace the electrolytic capacitors and cooling fans to have performed what insiders like to call “tenth-year maintenance.” Experience has...
