Hi!
I have in the system one Bluesolar 150/100. I have 12 solar panels with 330W each.
Only the half is connected (2 parallel x 3 series)
The problem is that when the solar power is rising above 1000W the Bluesolar shuts down and alarm is triggered:
Alarm #28 Charger power stage issue
If the power is under 1000W everything is working fine.
The firmware is the last available v1.59
Is there any solution?
Thank You!
What are the panel specs?
Is this a 12/24/48V system?
What is attached to it?
A bit more info would help.
Panels are Sharp NU-JC 330
Voc 41.32
Isc 10.35
48 Volt battery
Multiplus II 48/5000 
The error description is as follows from docs:
This error will not auto-reset.
Disconnect all wires, and then reconnect all wires. If the error persists the charge controller is probably faulty.
Note that this error was introduced in v1.36. So when doing an update, it might look like the firmware update caused this issue; but it doesn't. The Solar charger was then already not performing 100% before the update; updating to v1.36 or later merely made the issue more visible. The unit needs to be replaced.
Thanks, but I readed also the docs.
What other option I have?
