Renogy mppt charge controller issues
Howdy all
I've got an issue with my Renogy Rover 40v mppt.
Here's the pertinent information...
400w PV panel
Rover 40
2- 200aH Renogy pure gel batteries in series (24v)
I'm using the bluetooth dongle with the app on my phone
Here's the issue...
With the mppt set to 24v and gel batteries, the advanced settings seemed to be set for a 12v system. For instance, high volt disconnect showed 16v and float charge 13.8v. You can see more details in the screenshot.
I am unable to change any of the advanced settings that have gray cells (all but one of them). I also cannot change them on the unit itself.
Here's what I have done so far...
- I reset the unit per Renogy's instruction
- Under battery type I put it in "User" mode and was able to change the settings, but they all max out at 17v.
Renogy customer service, while being very friendly, have not provided any substantive help.
Any whizz bangs here that might be able to help me? I suspect I might have a defective unit but need to find out what's really going on and then maybe I can convince Renogy to step up.
Thanks in advance, Gary
