Had a 8kw system installed early this year. Has a SolarEdge 7600HDWave inverter connected to the electric panel with a disconnect box with a fuse (or maybe a fusible link?) between them. Yesterday afternoon the system stopped producing power and when I inspected it today I found the fuse box plastic insert deformed from the heat of that link failing. Breaker never tripped. I switched off the system at the breaker and contacted my installer.
Why would the fuse melt before the breaker tripped? What should the installer inspect while replacing the failed part to reduce the chance of it happening again?
Thanks.
