Wondered if anybody has had luck fixing Schneider MPPT80 600s that they suspect have been subjected to an unknown over voltage incident.
We lost 4 of them - can't figure out how the over voltage occurred but they are definitely fried and won't come online. We tested the solar inputs on a very cold very sunny day and nothing was even close to 600V (mostly high 200V, low 300V @ 20ºF).
