Last month one of my SolarEdge inverters stopped generating power. I called New Dawn Energy and they had SolarEdge to remotely diagnosed the system. It turned out this time, it will take more than a simple firmware update. A replacement is approved through their RMA process. This all happened on August the 22nd.
This is the second replacement in three years of operations. SolarEdge really needs to improve their quality process.
Today, the unit finally got replaced after 25 days. During this time 50% of my total solar power was dormant. For something that you think should be part of utility, this is certainly a very long lead time for replacing something that I think would be pretty critical if I was off-grid. Glad I was not!
