Esteemed Wrenches: Wrench esoterica time. another contest like Mick's to win the chance to take time off.
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.
