Make sure the old modules are resistant to Potential Induced Degradation
(PID). The new transformerless inverters can induce PID on non PID
resistant modules. This issue surfaced with the installation of
inverters that did not solidly ground either conductor. Drake Chamberlin Athens Electric LLC Ohio Electrical Contractor's License 44810 CO Master Electrician's License 4526

Wrenches I would also be surprised if the old 2500 would last very long. Better off with a SB5.0-41 and if you need RSD then add that in also.

These older Sunnyboys do not comply with latest UL standards regardless. If its 
a new installation, a savvy utility  / AHJ will catch this.

Jay: Some years ago I mis-ordered 5 SB2500s for 208 three phase and it turned out the system was 240 VAC three phase (open delta). I had to return the inverters to the factory to be converted and I had to rewire all of the arrays. So no, I don't think this can be done in the field.
