Allan,
Yes, probably. However....
IF your very early inverter has a serial # <50 or so, there was a
board issue and it will not stack unless that board was changed out.
They got most of them but not all. :)

A customer has a late-2005 SW4024 with Rev. 4.30 firmware. He needs to
add a second inverter for series stacking to increase output to run a
big well pump. We have an early SW4024 with Rev 1.0 firmware, and we
have both Rev. 4.01 and 4.10 firmware chipsets in our parts archives.
Are the two inverters compatible if series-stacked with a firmware
upgrade?
Thank you.
