[RE-wrenches] Equalizing with SW inverter

[R Ray Walters]

I had so much trouble EQing with the SWs, that I just told the customers to bulk charge in the early AM with the genie, and then use the PV in the afternoon to reach EQ voltage, or temporarily set the bulk voltage higher in the normal SW charge mode to EQ.
We don't EQ as much as some (twice a year on avg), so it has been less of a problem.
Phil's trick sounds interesting, but the customer is still playing with settings that they shouldn't have to deal with.

Setting the cursor to EQ just means the system will perform an EQ the next time the genny runs, and that might be some random time in the future. Setting the cursor to EQ and manually starting the genny works sort of, but somebody has to stay around and babysit the system to manually turn the genny off once the charge is done. Not ideal.
