Good point 12vman, I have never done an equalization charge either. In fact I can’t. What I did was to run my six 240 watt panels as pairs running in parallel. I get 32v @ about 15 amps per pair on a bright sunny day. Each pair is controlled by a 20 amp (dirt cheap) charge controller (eBay). The three of them run in parallel to the buss bar. They are pre-set to run a three stage charge cycle with absorption voltage of 28.8v and then float at 26.7v My batteries boil near the end of the charge cycle and seem to maintain the batteries well. There is no equalization option but in the past seven months I have not seen any change in the specific gravity during my monthly maintenance checks so stratification is something I am not worried about.
