Hello,
I have two almost identical set ups and the difference between the set up is the Charge Controllers, and I am having an issue with the Rover Controller.
Both have 4 100w panels, 200 Ah 12v battery and a Unique Solar Fridge (UGP-290/260 <- same compressors and power draw).
The first set up has been running for a year + with the fridge on the commander's load terminals. No faults, it just runs the fridge without fuss.
Tried to set up a similar set up this year with a Rover and it will inconsistently throw the E4 fault on the fridge when connected to the Rover's load terminals.
Fridge runs fine directly to battery.
Would like to have it on the load terminals to monitor real world power consumption vs power production.
I know the first step is to swap the charge controllers between set ups and see if that identifies any issues, but I wont be able to until this next weekend (first cabin is occupied and using the fridge) plus its on an island over an 1hr away. Not too conducive for a mid week night run.
Is there a difference between the Rover's load terminals and the Commander's? Where one would run the fridge and the other would not?
The manuals provide not enough insight for me to determine that.
Any insight / trouble shooting tips appreciated!
I'd like to formulate a plan of attack for when I make it back this coming weekend.
Thanks in advance.

Hello,
The load terminals of the Commander 40 and Rover 40 should be working the same. Until we can get more information, it might be advantageous to have a multi-meter with you to observe if there are any differences on the load terminal itself. E4 indicates a short circuit so perhaps you might be able to see some differences. Upon normal Renogy business hours, we will investigate to see if there are other solutions.
All the best,
Renogy Team
