Replacement for SB 8000 US

[imstilllarry]

At 10 years and one month my inverter has started getting 6404 errors and making an intermittent buzzing noise. It is still producing but is down at least a third compared to the same period over the last 10 years. My ground mount array is still working fine. SMA does not sell the 8000US inverter anymore and told me to find a refurb unit. Over the past month I have been unsuccessful finding a unit anywhere. I would like to just replace the inverter with a reliable easy as possible new inverter. One that looks like a good replacement is the Tigo 11.4K. Anyone have experience changing out the SB8000US with a Tigo? Thanks Larry

I don't have experience with a Tigo but I suggest you ask their customer service for help.

I take it SMA says the warranty is up on the unit you have?

SMA should also have something in their current line up that would be direct plug and play.
