Hi, We have made up a 12v 600Ah LiFePo4 battery using a 100/20 Victron Controller. we had 2 x 200W solar panels ready to power a road sign, so all they had to do is connect the PV and the load and they were done, however when our installers installed it to a load, they told us there was no power on the load available, so they used out direct power feed we had built in as a redundancy. We went down a few hours later to check what they had done and there was clearly power available at the load. Is it possible they short circuited it during install on the load or PV and its simply reset itself? We cant check the BT as its installed in a way that is not possible. Any thoughts would be helpful.
