If you cannot change grid code or access advanced settings:
You will be prompted for the Grid Code password in VictronConnect (via the "Grid" tab) or in VE.Configure tools when you try to change:
When installing a Victron Energy system (specifically Victron MultiPlus or Quattro inverter/chargers) that will be connected to the utility grid, one of the most critical final steps is configuring the Grid Code. This often confuses new installers because it requires a specific "password" to unlock settings that are typically hidden.
Here is a comprehensive write-up regarding the Grid Code password, why it exists, and how to handle it during an installation.
When installing or configuring a Victron Energy system that interacts with the utility grid—such as the MultiPlus-II or Quattro—the "Grid Code" settings are protected to ensure compliance with local electrical regulations. The "Grid Code" Password Explained
Unlike standard device PINs, the Grid Code Password is specifically intended for certified installers and is not public.
Primary Access: You must contact your authorized Victron dealer or distributor to obtain this password. They are responsible for ensuring the person making changes understands the legal and safety implications of grid settings.
One-Time Exception: During the very first initial installation, you can typically select a grid code once without a password. Any subsequent changes to this setting will require the protected password.
Purpose: This lock prevents unauthorized users from disabling safety features like Loss of Mains (LOM) detection or changing country-specific frequency and voltage limits, which could lead to illegal grid feeding or equipment damage. Other Common Victron Passwords
Users often confuse the Grid Code password with other common access codes:
What is the default password for MultiPlus, MultiPlus-II, Quattro?
Most confusion arises from conflating two different security layers:
| Action | Interface | Password Required | Default |
|--------|-----------|-------------------|---------|
| Change grid code | GX Device / VictronConnect | Installer password | 00000000 |
| Change AC input current limit | GX Device | None (user level) | – |
| VEConfigure full access | PC + MK3-USB | None (if offline) | – |
| SSH to Cerbo | Terminal | Local GX password | blank |
| Modbus/TCP write | SCADA | Modbus password | password |
| Remove from VRM | Cerbo menu | None (physical) | – |
Final hard truth: If 00000000 doesn't work for grid code, and you don't have the custom password, you cannot bypass it without physical access and a factory reset via MK3-USB. No software hack, no remote override. That is by design for utility compliance. grid code password victron install
Headline: 🛑 STOP! Don't Get Locked Out of Your Victron System! 🛑
Are you installing a Victron MultiPlus or Quattro inverter/charger? If you need to reprogram the grid code (for example, changing regions or updating grid compliance settings), you’ve likely hit the dreaded "Password Required" screen.
Here is the breakdown on how to handle the Grid Code Password safely:
1️⃣ Why is there a lock? Grid codes are locked by Victron to prevent accidental (or unqualified) changes to safety parameters. Messing with these settings without knowing what you are doing can damage the unit or violate local utility regulations. ⚡⚠️
2️⃣ How do I get the code? You cannot just Google a static password. 🔹 Standard Method: Open a support ticket with your Victron distributor. You will need to provide the Serial Number of the unit. They will generate a specific password for that unit. 🔹 Pro Tip: The password is mathematically derived from the serial number. Some advanced installers use scripts to calculate it on-site, but Victron prefers you go through official channels to ensure compliance logging.
3️⃣ Safety First! Before you change that Grid Code: ✅ Ensure your AC input wiring is correct (L, N, and PE). ✅ Verify the local grid requirements (frequency, voltage windows). ✅ Have a voltmeter handy to verify the output after the change.
🔒 Pro Installers: Do you save the grid code password in your client's file for future maintenance, or do you lock it back down after the job? Let’s discuss best practices in the comments! 👇

When setting up a Victron system, especially the MultiPlus-II or
, the grid code password is a security measure designed to prevent accidental or unauthorized changes to local utility compliance settings. Incorrectly configuring these can have serious legal or safety implications, such as violating local anti-islanding laws. Understanding the Password Types
It is common for new users to confuse the Bluetooth PIN with the Grid Code Password.
Bluetooth/App PIN: By default, this is often 000000. On newer models like the Multi RS Solar
, a unique PIN may be printed on a sticker on the side of the unit. If you cannot change grid code or access
Grid Code Password: This is a specific 8-digit code required in VEConfigure or the VictronConnect grid tab. This password is not public and is officially provided by Victron to authorized installers and distributors. How to Obtain the Grid Code Password
Because grid settings are regulated by law in many regions (like AS4777 in Australia), Victron does not publish these passwords in manuals. How to change grid setting on Victron inverter? - Facebook
For Victron installations, the passwords you need depend on which software or settings you are trying to access. Quick Password Reference General Settings (VictronConnect): (all lowercase) or
(all uppercase) to enable settings when using an MK3-USB interface. Bluetooth Pairing/Device Access: The default is usually Grid Code Password:
This is a restricted "Installer Password" and is not public. Understanding the Grid Code Password Grid Code Password
is specifically required when you need to change the grid standard (e.g., from G98 to G99) or disable Loss of Mains (LOM) detection after the initial setup. Grid code password? - DIY - Victron Community
To access or change grid-sensitive settings on a Victron system, you need the Grid Code Password. This password is a safety measure to ensure only qualified installers configure parameters that affect the local electrical grid. 1. The Password The standard password for Victron grid code settings is: BBB0000 (three capital Bs followed by four zeros) 2. When You Need It
You will be prompted for this password when using VEConfigure or the VictronConnect app to:
Select a specific country grid standard (e.g., VDE-AR-N 4105, AS4777.2). Adjust LOM (Loss of Mains) detection settings. Modify frequency or voltage trip points. 3. How to Enter the Password Depending on your interface, follow these steps: Using VictronConnect (Recommended for Mobile/Bluetooth): Connect to your MultiPlus, Quattro, or EasySolar. Go to Settings (cog icon) > Grid.
When you attempt to change the Grid Code, a prompt will appear. Enter BBB0000. Using VEConfigure (PC via MK3-USB Interface): Open your configuration file or connect live to the device. Navigate to the Grid tab. Click on the grid code selection dropdown. Enter BBB0000 when the password box pops up. 4. Important Safety Note
The grid code settings are governed by local laws and utility requirements. Selecting the wrong grid code or manually bypassing safety limits can: Lead to fines from your utility provider. Void your connection agreement.
Create a safety hazard for line workers during a power outage. 5. Troubleshooting
Password not working? Ensure you are using capital letters (BBB) and not numbers or lowercase. When installing or configuring a Victron Energy system
Settings are greyed out? Ensure your firmware is up to date. Some older versions may require a firmware update before certain grid codes become available.
Can't find the menu? If you are using a GX device (like a Cerbo GX), you generally cannot change the internal inverter grid code from the GX Touch screen; you must use VictronConnect or VEConfigure.
Configuring a Victron Energy system often requires navigating multiple layers of security. While basic device access is straightforward, the grid code password is a restricted security measure intended for professional installers to ensure compliance with local utility regulations. 1. The Grid Code Password
The grid code password is not a single "default" number like basic PINs. It is a restricted code used specifically for the Grid tab in Victron VEConfigure software.
How to Obtain It: You must generally contact your Victron dealer or distributor to request this password.
Why It Is Locked: Grid codes govern critical safety features like "Loss of Mains" (LOM) detection, which prevents your inverter from "backfeeding" power into a dead grid (islanding)—a major safety risk for utility workers.
Legal Requirements: In many regions, such as Australia (AS4777), laws require that these settings be protected from unauthorized tampering. 2. Common Victron Passwords & PINs
If you are looking for general device access rather than restricted grid settings, one of these common defaults often works:
National electric grids (like the EN50549 in Europe, UL1741-SA in the US, or G98/G99 in the UK) are complex, synchronous machines. They require all connected power sources to play by strict rules. These "Grid Codes" dictate everything from voltage and frequency tolerance to how quickly an inverter must shut down during a fault (islanding protection).
If a homeowner could freely change these settings, they could accidentally program their inverter to backfeed a dead grid line during a repair, electrocuting a lineworker. Or, they could set their frequency window so wide that their system destabilizes the neighborhood's power quality. Therefore, the password is not about protecting the device from the user; it is about protecting the grid from the user.
Q: Is the grid code password the same as the “VE.Bus password” or “VRM password”? A: No. These are entirely separate. VE.Bus password protects system configuration; VRM password is for remote monitoring. The grid code password lives only inside the inverter’s grid protection settings.
Q: Can I retrieve a lost grid code password from a backup file?
A: If you have a previous .vcs (VEConfigure settings) file, opening it will not show the password. The password is hashed. You can, however, re-upload that backup file to the device, which will restore the previous settings (including password). This is the only recovery method.
Q: Does firmware update reset the password?
A: No. Updating firmware preserves all user settings, including the grid code password. A factory reset is required to revert to 00000.
Q: I’m only using the Victron in off-grid mode. Do I need a grid code? A: No. If the grid input is never connected, you can select “Disabled” or “None” for grid code. In this case, no password is required. However, many installers still set a dummy grid code for future-proofing.
Q: What happens if I enter the wrong password 10 times? A: The device enters a “cooldown” period. For 30 minutes, it will reject all password attempts and may temporarily disable grid connection as a safety measure. Power cycle the device to reset the attempt counter.
