only two circuits i can get out of each panel is to either wire it the way it is or i can get 3 individual circuits which is only 24 cells each which again puts me on the low side.... each row of cells in diagram is 12 long and just went outside and row of 24 cells was making 14.45 volts...again no sun visible and some snow on the ground....or the series/ parallel route opens up another circuit...right now i also got 28.5 vdc sharing those 4 centre cells...if that makes sense
today i hooked the 72 cell up to first atv batter with 11.4 volts in it and i pulled it off cuz it was at 18.4 and climbing
next i hooked updirect to old 27 that came with trailer, been on the charger and was at 13.4 with surface chanrge and that one was at 16.4 with 9.2 amps going into it.....from 43 volts on the panel
i will also measure the 60 cell too
7.4 amps at 15.6 volts
after i pick up my son from school
