    You don't get it. You are very dangerous. You have ZERO control of fault current. At best all you can do is coordinate OCPD to mitigate damages. You are beyond help and not willing to listen. I will help you no more.

      And so ends the great junked battery experiment. Interesting to get an update. This gives "nothing ventured, nothing gained" a whole new meaning.

        It could have resulted in a worse conclusion. Lucky no fire broke out.

          But keep hacking away.
          thats how mankind has always learned and always will. learn from mistakes. if you dont fail you will never learn anything
          thats how the shuttle programme was run, after the challenger disaster , O rings were installed, then after columbia , inspect foam dislodgements .

            will keep you updated , have adjusted the charge voltage to 27.4v to minimize plate corrosion. the remaining used car batteries are all ok.. i think it was the bad battery that blew 2 inverters, now the inverter im using doesnt cut off with large currents as it was doing before. i do listen sunking, i will install the right size fuses to the cabling i am using

              You are not learning anything for mankind. Everyone knows you have built a bomb except for you.

                What is scary is that while he may learn from his mistakes, he may not be healthy enough to do anything to improve the system if a fire should break out.

                  Everyone makes mistakes, but not everyone learns anything from their mistakes. What do they say about: "doing the same thing over and over again and expecting different results"?

                        will keep you updated regardless, whether my junked batteries explode or serve me well for years. right now this bank of remaining batteries are ok. dropped charge voltage to 27v, SG is good. running fridge , washing machine , laptops , coffee machine by day. dont use it at night. use a different bank at night. as before observing charge current and voltage battery temp for any problems. will test any additional batteries more thoroughly before adding them. as for fuses will go to 20 amp per parallel battery with a total of 5 parallel groups

                          ok this junked battery trial is finished, iv found the light SLI batteries are totally unsuited to RE. they overcharge and overheat. even at low charge voltages they overcharge. after a few weeks they start to get hot even when the sun is down they keep drawing current from the other paralled batteries. draining the whole bank so in the morning there is no charge left. iv found the 4 x 4 / marine batteries work well with RE, a set bought new a year ago are still performing well. although i never discharge them ,
                          as for using junked batteries i think is a waste of time. best value would be new deep cycle FLA batteries. shop around can get them for a reasonable price.

                              Facing reality like a Man. I'm really glad that no disaster occurred during the testing.
