Code Password Victron Install - Grid
You have tried 00000 and it failed. Now what?
Pro Installer Tip: Immediately after installation, change the grid code password to a secure, documented number (e.g., your company ID) to prevent future tampering by other trades on site.
Modern inverters (like the Victron MultiPlus-II or Quattro) can feed power back to the grid. If done incorrectly, they pose serious risks:
The password prevents unauthorized changes to the grid code parameters—specifically the trip limits for voltage (V), frequency (Hz), and reconnect times.
To configure the grid code, you will need a Windows computer (or a VM/Mac with Wine) running VEConfigure (part of the Victron Toolkit) connected to the inverter via a MK3-USB interface or via VRM remote access.
Step 1: Open VEConfigure Connect to your MultiPlus or Quattro and read the current settings.
Step 2: Navigate to the Grid Code Tab Look for the tab labeled "Grid Code" or "Country Standard" within the configuration menu.
Step 3: Unlock the Settings You will see a button or a drop-down menu that is grayed out or prompts for a password grid code password victron install
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. You have tried 00000 and it failed
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.
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.
