Simulator don,t work for fork truck battery voltage.

[solarvic]

I am planning my system and ready to order battery and charge controler but your simulator only works up to 12 volt batterys. I want to buy a crown model 12-85-13 fork truck battery @ 24 volt that is suposed to be 630 amp 20 hr rate. I have 16 kyocera 158g solar panels that have these specifications pmax 158 watt, open curcuit voltage 28.9 v
isc 7.58 amp, vmp 23.2  imp 6.82. my coldest limit recorde is -26 but hasn,t been below -10 for years. Sometimes hottest temp is around 95F but not much in northern Pa. Part of the country that has lots of cloudy weather, about 80 miles north of Pittsburg, PA. I think the classic 150 should work with 4 sets of 4 panels. Should this be able to keep this battery charged. I also asked before about using the classic 150 to charge a 24 volt battery bank from a 48 vdc generator that can charge 95 amp for a 48 volt system. To start with I will buy 1 classic 150 if you think it will work for my solar. I will try it on the dc generator and will probably buy the second classic 150 if it works on the generator. Half crazy, I hope you can figure this out for me as I want to get the classic ordered.    Thanks Solar vic

Hi Vic,

I'm not HC (am more like Full Crazy),

But this seems to be a change in the Sim since the last time i used it.

EDIT:  Just looked again,  and seems if you spec the total AH capacity of the bank you do not need to choose the single batt V,  and number of batts.

Still, there may be flaws in the set of data available for voltages of single batts.  Looks like the stops on the bus are: 2, 6, 12 ,  and that is all.  Prob need to add 4, 8,  and perhaps 24,  36 & 48.  Altho,  believe if one specs the AH capacity for the bank,  this added data is not reqd.

Think that what it is getting at is to try to remove the possible ambiguity about the AH of a single battery in a string,  vs the total AH capacity.  Some folks do not calc the AH correctly in multi-batt systems.

Will play some more with the sim to see if one can just skip this step.
Guess one could say 2,6, or 12 V,   but make the total number correct for your 24 volts.  Recall that there was question about the total AH capacity of the bank ...  will look more.  Good Luck with the big new system, 

Looks OK if the AH of the bank is speced ...

Vic I tryed it at 4 6 volt batterys @ 24 volt 600 amp. Next step is 650 amp. They say that the battery I want is 630 amp. Maybe I should try 650 amp. They come up with #6 copper. I have 500 ft of #2 aluminum urd cable so I used the #4 copper chart. I am going to another website that has a chart for aluminum and copper in thier chart and see what I come up with. This wire I have has all the up to date specs that  are better than the older ones.  solarvic
