Microinverters vs String Inverters: The Shocking Truths

The insight that we can harvest from this model: as the module power increases, the number of homes for each fail increases correspondingly. Similarly, if the failure rate decreases, the number of homes to fail decreases as well, meaning more site visits and site calls. Therefore, for a 1% fail rate and 400W module using MLPE, the solar installer can anticipate failures for 2.6 homes

SolarEdge Inverter Failure

My SolarEdge inverter went to 0 power output 3 days ago, which may seem to be a just a random failure until you consider the history. This is the third SolarEdge inverter to have failed while in use at my home in three years. Every year the inverter has failed in either July or August, which is the hottest time of the year where I live.

What Happens If Your Solar Inverter Fails?

It is uncommon for solar equipment to fail, but it''s important to know what to do and where to turn if it does. If your solar inverter fails, your solar installation company is the best resource to turn to. (If you can''t remember who installed your solar energy system, check the junction box or inverter to see if the solar company left a sticker with their contact information.)
