SSH access

Sometimes you'd like more control over your Charge Controller, or you'd like to automate parts of your End-of-Line procedure, or perform advanced operations. That's where the SSH interface comes into play.

Potential for irreversible damage

Performing actions through SSH comes with its own risks. Only have trained personel perform SSH operations.

danger

We highly recommend disabling SSH access once the initial setup is complete. This improves cyber security.

1. Requirements

• Connect your computer to the Charge Controller through USB (CONFIG USB port) or LAN

2. SSH default credentials

Username	Default password	Info
charge	orange_zone
root	orange_zone	You won't be able to SSH into the Charge Controller with root access if it has been Eichrecht-locked

3. Establishing a SSH connection

1. Open a terminal that supports the SSH protocol
2. SSH into the Charge Controller by running the following command:

ssh charge@<YOUR CHARGE CONTROLLER'S IP ADDRESS>

3. Enter the password for the user charge (check above for the default credentials)

You should now be logged in per SSH.

tip

You might get a warning about certificate authenticity. Enter "yes" and press Enter to continue.

Example output

The authenticity of host '<IP ADDRESS>' can't be established.
ECDSA key fingerprint is SHA256:<HASH>
Are you sure you want to continue connecting (yes/no/[fingerprint])?
