[RE-wrenches] Trace Power Series inverter question

[Steve Higgins]

If you could dig up the old SWRC, that would work as a display.   As for
working with LFP... It's hard to say, but it's based on the old SW's and
should be configurable to charge LFP's... the only thing I don't know is if
it'll handle the quick voltage rise as well as the old SW's will.

Might be a good idea to take a look at one of the newer Victron 12V
inverters...
