MPPT 450/100 not giving power in Solar 2
Hi,
has solar 2 been working OK for a while and has just stopped working?
Do you get any output at different times of the day?
Hello @bladerunnervf,
The unit was running normally with the two solar ports. No, it doesn't give any output ay any time at all.
On the face of it, it sounds like a failure.
Is there any logging of status data or any error codes?
Can u get your installer to login and check it remotely?
You can check by connecting T1 string to T2 tracker. If it still does not work then the unit if faulty.
The other possibility is clamped on insulation. Happens alot more than you think.
Hello
@bladerunnervf ,
Remotely with Victron Connect I don't see error history I believe it must be seen on site from its display.
problem with the MC4 connector at the panel?
