[RE-wrenches] SMA SB 2500U

[Kirk Herander, VSE]

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

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.

Does anyone know if you can convert a
SMA SB2500U ( old red inverter) from 208 to 240vac?

Without using a boost transformer.

Thx
Jay

Peltz power.
