We have added a US 3000 Pylontech battery module to an existing bank of 5 US 3000s. On completing the installation and switching on - all battery modules are operating normally and the system itself is operating normally with no faults showing. the battery monitor however is showing the fault;
this alarm has been active now for 24 hours. what is the reason and how do I rectify it. I suspect it is a result of and arc when closing the fuse to the inverter - but as i say the alarm is still active.
The system consists of;
1 x 8KvA Quattro
2 x 150v 70A controllers
1 x venus GX
6 x Pylontech 3500 - set up in two strings of three
24 x 335w solar modules
