Unit was installed about 1 month ago.
15 panels, 5 strings of 3 Min Temp 5 degrees C Max 50 degrees C
Freedom Won LiFePO4 10/7 battery CCGX color control to a Victron 5 Kva Multiplus 2
Unit worked perfectly, Now not even one L.E.D. Light is on. It appears to have a dead short on the PV input. If connected no voltage reading if disconnected we have a normal string voltage reading.
All battery terminals are well installed and tightly fitted
Any way of disassembling the unit to inspect?
Any explanation as to what may have caused this failure ?
