After replacing a failed MPPT 100/50 with a new identical unit, its Bulk and Absorption lights are blinking fast. What does this indicate? This is one of 3 MPPTs on my boat - remaining two show steady (blue) Bulk lights, seem to work fine. Posts about similar behavior didn’t indicate anything conclusive…?
Hi
You can probably find your answer in the tookit app.
Yes, thanks - I did look it up, the problem is it lists several alternative error codes (all of them have the same blinking pattern) and I don’t know where to find the specific error. Is there a way?
Is it a Blue Solar or Smart Solar?
With a Smart Solar you might get more information with the VictronConnect app.
The tool kit app shows 3 errors with possible causes and solutions.
One says to reset and power cycle the device. → the error is still there? → contact your seller
The other two say the unit is defective and needs to be replaced. → contact your seller
Probably need to program it.
Matthias: it’s Smart Solar with Bluetooth.
Ah… any clue - how? It’s Smart Solar with Bluetooth.
Thank you. I appreciate the help offered by all who responded. I think the reset (by unplugging the wires, then reconnecting the unit) helped. It seems to be working fine now.
