Hi
I have 2 x morngstar 45amp mppt controllers installed with
1st controler 3 x 155W 24v 43.4voc
2nd cont 3 x175w 24v panels
batteries 12v 600 amp 2 v GNB ABSOLYTE
Everything has been running fine for a month until I started getting a LED Fault code on the 2nd controller
3 x175w 24v panels
FLASHING G/R
Y SOLID
The voltage on the displays does not seem high
Battery 12.3v

Any help and advice would be very much appreciated

According to the manual, page 41, a G+Y to Y+R means either the BTS has been removed or faulted or the remote battery sense has been removed or faulted
I would check your wire where they are secured in the controller ( terminal blocks )
You have to power cycle the controller to reset the fault
Hi Thanks for your reply
G / R sequencing Y solid
im not sure it the bts or bvs but i will check wiring and try disconnecting both and switching the power off resetting & restarting the controller
hi
I have removed both sensors but still im getting the same fault
What do you mean by power cycle?
I have also noticed that on the controller thats working correctly i get 12.5v battery volts, but on the faulty controller its showing 55v battery voltage i have tried resetting, turning the power off (battery & pv) but with no luck.
I have checked the battery voltage at the batteries and i get the same reading as the correctly operating controller gives 12.5.
Any help would be appreciated
