There are two ways. Duracell account: sign in with the same email and password as the Duracell app; nothing to install at home, and Volt can change the work mode. Raspberry Pi at home: a small program called Volt Bridge runs on a Raspberry Pi on your Wi-Fi and talks to the inverter directly, so every setting is available.
What you need: a Raspberry Pi (any model with Wi-Fi or Ethernet: Zero 2 W, 3, 4 or 5), a microSD card of 8 GB or more, its power supply, and the inverter's Wi-Fi dongle on the same network as the Pi.
volt-bridge, a username and password, your Wi-Fi name and password, and under Services turn on SSH. Write the card.ssh USERNAME@volt-bridge.local with the username you chose. Type its password.If it can't find the inverter: your router's device list shows the Wi-Fi dongle's address (it often appears as "Espressif" or the inverter maker's name). Run the installer again with it: sudo bash install.sh --key vb_... --inverter 192.168.1.50.
Only one program can talk to the dongle at a time. If something else polls it (a Home Assistant integration, say), stop that first.
To see what the bridge is doing: journalctl -u volt-bridge -f. To stop it: sudo systemctl stop volt-bridge.
Volt reads every change back from the inverter. If a value doesn't stick, the app tells you and shows what the inverter really has. Changes are off until you turn on Allow changes in Settings.
On the sign-in screen tap Forgot password?. We email you a six-digit code.
In the app open Settings, then Account, then Delete account. Your account, inverter link and all stored history are deleted straight away.
