since summer started, i had been setting my reserve (time-based) to just get thru being self-powered 3PM-12AM or something like 45% based on my usage. before "export everything" existed, this is all i could do to maximize $$. in the winter i needed to set the reserve higher (about 60%) since there wasn't enough solar available to get me back to 100% if i let it go down to 45%.
the other day i started experimenting with "export everything" and setting the reserve to 25%.
im now +$2 or so over where i was just exporting solar, but i find that the PW will just start at 4PM and go gangbusters for a few hours until it hits the reserve, and then i'm importing again during some part of peak and shoulder times. it seems like i do a little better money wise if i just "export everything" starting at 4PM until the PW hits about 65% and then switch back to solar-only export mode.
in theory this shouldn't make a difference money-wise (vs just letting the PW discharge itself entirely during peak) but somehow it seems to. i need to experiment more.
