My church has a largish solar PV installation.
It is a Solaredge installation with 4 inverters. Each inverter has either 2 or 3 "strings". Each string has 10 Solaredge P600 optimizers that has either 1 or 2 panels attached.
On two of the inverters we have string failures.
Both of the inverters with failures had 3 strings.
On one of the inverters it is shows 2 of the 3 strings as essentially dead.
When looking in the layout view, it shows 0Wh to 15Wh of production for the optimizers in the "dead" strings.
Other optimizers on a "good string" have generated during the same amount of time ~1kwh or ~2kwh. (~1kwh for one module attached, ~2kwh for two modules attached to the optimizer)
All the optimizers appear to be communicating with their inverter (I see "30/30" on the inverter's LCD panel.)
Anyone heard of an issue like this before?
The installer should in theory take care of things. But I'm less than thrilled with their response so far. It's been 2 weeks since I told them about the issue, and during that time it's gone from 2/10 strings failing to 3/10 failing. And I still don't have an ETA on when they'll have someone physically out to the site to investigate.
