I installed a lot of Sunny Boy, Xantrex GT, Outback GVXT, Fronius IG and IG Plus, and re-branded SunPower inverters over the many years, and I have promoted the SB line to both the in-warranty and out-of-warranty clients whose inverters have failed. I especially like the multiple MPPT inputs and the SPS.
What bothers me, though, is the 5-year product warranty. What happened to the 10-year product warranty? Does one have to pony up $$$ to get a 10-year warranty for SMA. What about the the other manus?
I would like to stick with the SBX.X even if the -41 version does not come with a back plate.
So, is the std warranty for SBX.X products 5-years? Is there an "upgrade" to a 10 -year warranty, and what is the cost? What about about Solar Edge, Fronius IG Plus?
Any help would be appreciated
