Afternoon,
I have looked through the internet for the right settings for the Tupperware batteries dt120, I have the general info for a st acid battery but nothing specific.
Does anybody know
1, what are the battery specific voltages?
What charge controller setting s should I use?
Thanks,
Simon
Best I could find is Superbatt, not Tupperware. Guessing your spell checker got sponsored ;-). If I'm right, these appear to be SLA so standard AGM or lead acid values. I'd set absorption to 14.4V, float about 13.7V. But that would be max.
If you have a battery monitor, the 120Ah is at C100, not the more normal C20. So be prepared to downrate capacity, maybe to 100Ah. Unless you only have a general draw in the region of 1A.
