Quick Start With Renogy Rover or other SRNE (re)branded charge controllers

If you haven't already, click here to view how to clone this repo and install the service.

If you don't have a cable to connect to your device, click here

Once everything is installed, you're ready to edit the configs. You will cd to the program directory.

cd /opt/solarthing/program/rover

Copy some template config files (default_linux_serial and rover_template or rover_setup_template)

# sudo should not be required unless permissions were not set up correctly (add yourself to the solarthing group)
cp ../../config_templates/io/default_linux_serial.json config/
cp ../../config_templates/base/rover_template.json config/base.json
# or do this if you want to run the setup program:
cp ../../config_templates/base/rover_setup_template.json config/base.json

Edit base.json

{
  //...
  "io": "config/default_linux_serial.json"
}

Other parameters

The bulk_request parameter is by default true in SolarThing versions >= 2020.3.2. By keeping it true, requests to the rover are a lot faster.

Configuring the dummy file

If you want to test this program without a rover, both the rover and rover-setup program types support it. You can edit your base.json like so:

{
  //...
  "dummy": "test/dummy_rover.json"
}

If the default file in test/dummy_rover.json doesn't work for you, feel free to copy it to your config directory and change it.

I want to test this without a Renogy Rover

Make sure to configure the dummy field as the above section describes, then just run ./run.sh.

I'm ready to use this for real!

Once your configuration is how you want it, you can go back to the quickstart to enable and start the service.

I want to test this easily!

See Rover Setup Info for information on how to use the rover-setup program.

Setting voltage values of the User battery type

If you want to set values of the user battery type, this cannot be completely done from SolarThing. You have to manually go to your Rover and set it to the User battery type. SolarThing can set the battery type of your Rover, but if you set it to User through SolarThing, the values will be locked.

<Insert Advanced Feature> isn't working on my Rover!

Yes, I hear you. When I first started trying to configure certain things on my Rover, it just straight up didn't work. Here's an incomplete list of things I was unable to do:

  • Settings certain values
  • Getting (accurate) special power control values
    • These values didn't really seem correct (maybe they only work on certain charge controllers or only when the battery type is lithium)

Note that a lot of the more advanced features are untested. They exist in SolarThing because they were in the Rover's Modbus protocol document.
