When Voltvik is in setup mode, the setup page works while the phone is connected to Voltvik’s own WiFi network. The network is called Voltvik- followed by four uppercase characters, for example Voltvik-BE84. It is open and should never ask for a password. The suffix separates multiple devices from each other and is fixed. The name of your device is shown on the third settings page, NETWORK, on the screen, as “Connect to Voltvik-BE84”. When the device is already connected to your own WiFi, you instead open the device’s own IP address, shown on the same page.

1. Check that WiFi is turned on in the Voltvik settings, and that the phone is actually on the network beginning with Voltvik-.
2. Accept the “No internet connection” warning and choose to stay connected.
3. Turn off mobile data temporarily if the phone jumps back to the regular network.
4. In setup mode, type 192.168.4.1 manually in the browser address bar.
5. Try another browser if the page still does not open.
6. Forget the network beginning with Voltvik- on the phone, connect again and try once more.

If you do not see a network beginning with Voltvik- in the phone’s network list at all, go on to “I cannot find the Voltvik network at all” further down.

You cannot lock yourself out. Voltvik never gives up its setup network without having something to fall back on. If it cannot contact the home network, Voltvik-XXXX comes back by itself. You need neither cable, PC nor to reset anything.

How long you have to wait depends on what happened:

• If the device has never had a network before, the setup network is there right away.
• If you have driven somewhere where the saved network does not exist, the network beginning with Voltvik- reappears after about 20 seconds.
• If you typed the wrong password under “Connect to new WiFi”, it can take up to a minute before it gives up and lets you back in.

Connect the phone to Voltvik-XXXX again, open 192.168.4.1 and enter the password again.

The device also cleans up after itself at every startup. If a half-finished attempt remains in memory, it is deleted before the radio starts, so the setup network comes up cleanly. If something still seems stuck, there is a last resort described below.

If, against expectation, the setup network does not appear, Voltvik has a built-in rescue you can trigger from the screen. It requires no cable, PC or app, and it does not touch your Victron setup: encryption keys, addresses and names remain.

1. Turn the power off and on again.
2. Press the screen five times within twenty seconds after startup.
3. The screen flashes three times as confirmation that the rescue has been triggered.
4. The device forgets the WiFi setup and restarts the Voltvik-XXXX setup network.
5. Connect the phone to the network beginning with Voltvik- and open 192.168.4.1.

If the flashes come, the device has heard you. If they do not, you did not manage all five presses within twenty seconds, and you can just power off and on and try again.

Remember that Voltvik transmits on 2.4 GHz. Some phones hide such networks when they are in a mode that favours 5 GHz, so check that the phone shows all networks before you conclude.

This is normal during the first few seconds after startup. Voltvik has been given an address to listen for, but the radio has not yet had time to hear the device. The message changes to something more precise after about fifteen seconds — we deliberately say nothing definite until the radio has had a fair chance.

1. Wait half a minute.
2. If it still says the same, it is a real fault. The message has then changed to one of the two below.

Voltvik hears the device — it is powered on and within range — but cannot unlock the messages. The signal strength is shown beside it as proof that the radio part is fine, so you do not need to move anything. Almost always, the encryption key is wrong, or Instant readout is not turned on.

1. Open VictronConnect near the relevant device.
2. Go to Product info → Instant readout → Show, and check that Instant readout is turned on.
3. Copy the whole key again, with no missing characters or extra spaces.
4. Paste it into the setup page for the same slot and save.
5. Use one key per device. A SmartShunt key will not work for an MPPT, charger or other shunt.
6. Remember that this is not the Bluetooth PIN code printed on the Victron device.

Voltvik does not hear a single beep from the address that has been entered. Changing the key will not help then — either the device is turned off, too far away, or the address has been mistyped.

1. Check that the device, battery or sensor has power and that Bluetooth is active.
2. Check the MAC address character by character against the setup page.
3. Move Voltvik closer to rule out range. Metal walls and battery boxes attenuate the signal strongly.
4. Open VictronConnect and check that Instant readout is enabled on the device.

The device delivered data earlier, but has been silent for more than five minutes. By far the most common cause is that VictronConnect is open on a nearby phone: Victron stops broadcasting while an app holds an active connection. If it has been silent for less than five minutes, Voltvik instead writes last seen N min ago.

1. Close VictronConnect completely on all nearby phones — locking the screen is not enough.
2. The value normally returns within a minute.
3. If that does not happen, check power and range as described above.

If you see example values or pages for equipment you do not have, Demo mode is on.

1. Keep your finger on the screen until the settings open.
2. Swipe to page 2 VIEW and press Demo mode so it turns off.
3. Swipe down or press Back to exit. Automatic page switching now skips pages you do not have equipment for. If you swipe yourself, you still reach all pages — they just have no numbers.

The language is selected from the setup page on the device. The setup page follows the same choice as the screen, so both change language together. New devices are set to English from the factory.

1. Open the setup page from Voltvik-XXXX or the device’s IP address. The page opens in the language the device is set to.
2. Choose Language and set Norwegian, Swedish, Danish or English. The setup page changes language as soon as you choose, before you have time to save.
3. Press Save language. The screen follows immediately — the device does not need a restart.

The screen may be asleep or without power. Voltvik has no on/off button — it starts by itself as soon as it gets voltage.

1. Touch the glass once and release. If the screen was only asleep, it wakes up.
2. Check power supply, cable and fuse.
3. Cut the power for a moment and connect it again. Voltvik always turns on the backlight at startup, no matter how low the brightness has been set. If the screen still stays black, it is about power — not a setting.
4. Check the polarity before trying again: red is plus, black is minus.
5. Try starting via USB-C to rule out a fault in the fixed cable or power outlet.

Alarms and warnings from Victron SmartShunt/BMV-712, SmartSolar MPPT and Orion XS have been verified on real equipment and are shown on the screen.

1. Open VictronConnect and connect to the relevant device for details.
2. Check for low or high voltage, high temperature, overload or other fault code.
3. Correct the condition on the original equipment. The alarm disappears when the device reports that the problem is gone.
4. Do not use Voltvik as the only safety or alarm system.
