The commit listed above (f61eadb5) includes the scaling, and it is on master (currently 4b753dc7). If upsc shows "driver.version.internal: 0.28" or 0.29, you have it all installed correctly.

As a machine-parseable number, it's meant to be a hint to graphing software. (The NUT CGI scripts use it to define the various color bars for normal, high and low voltages.)

In that case, I'm inclined to change it back to 230V before the next release, since we don't have any more accurate information as to what the 'V' digits really mean.
