Hello,
I have a small 4 element Trojan 12 V @ 105 A-h bank.
It is wired with 100 mm2 copper wire soldered to good terminals.
It has been in service for 15 months with no problem.
Since a couple of months we notice frequently HVD (high voltage Disconnect) contition fired up by the MorningStar PWM regulator.
Seems to be that a contact opens in one battery.
I have also noticed that one positive battery terminal, instead of being dry and light gray color, is dark and seems humid.
There are also small signs of corrosion in that terminal.
I cannot imagine how acid could be present well up of the max level it has inside the battery.
There is not sign of corrosion on other terminals (the ones that are light grey color and dry)
Electric behavior of batteries is normal.
When this happens, I stop completely the system, clean up all the 8 terminals and restart the system.
What can I do ?
Do you need pics of the terminals ?
Thanks for your help,
Horacio
