Since it's a TC I assume all these batteries are AGM. Some times AGM will want 14.4 volts but some only want 14.3. Find out what Crown wants for your model battery or you will probably want to use profile 18 in table 4 on page 16 of the users manual.
Add up the total amp hour rating of all 3 batteries and set P3 to that number.
In profile 18 (generic AGM with NO high voltage finish) you will see that P15 is set at 15 volts. That number only applies when using the sc2030 solar controller.
The batteries are FLA Interstates made by Crown, the Crown model number is 31DC130. I have 2 of these, 130AH each and both are new. The info I find for these batteries is absorpion 14.5V equalize 15.5V and float 13.5V. As of now I have P1 set at 14.2 P2 at 2.0 and P3 at 260. Does this sound correct?
Why did I have to force the converter into boost mode to get it to get the voltage high enough to reset the AH % back to 100? With the 120V shore power un-plugged, I left all of the 12V lighs(led inside, std bulbs outside), range fan, etc. on last night for several hours and then when I plugged it into the shore power it still did not kick the converter into boost mode.... would this be normal? Did I just not use enough power for it to charge at a high rate?
Thanks!
