correct setup for CANBAT LiFePO4 12V SYSTEM - with 800w solar in series

Hi all.

so the battery runs my pc and other things fine. some days the battery is hardly used. hasn't gone below 13 volts. o sunny days the 80amp breaker will trip. Looking at the history shows the battery hitting 16.26v I have manual entered the info and though I had fixed the issue until i was running my pc and slow cooker on the same day. any help will be much appreciated

It would seem that the 80a breaker is tripping, causing a brief voltage spike on the output of the mppt.

Solution is probably to use a better quality breaker.

ok thank you. I was thinking it might have been the BMS fighting with the controller. I was able to catch the trip on the graphs. would you still say this was still due to faulty breakers. most of the time its the breaker on the + wire and rarely on the - wireCapture.JPG 211531950_230552442250274_698871380014170325_n.png 214633741_583741129280064_8504825213536904627_n.png
