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:
| 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.
Unlocking Victron Grid Code Settings: A Guide to the Grid Code Password Installing a Victron Energy MultiPlus
, especially when configuring an Energy Storage System (ESS), requires a critical step: selecting the correct grid code. This step dictates how the inverter behaves when connected to the public electricity grid. When you attempt to change these settings in VEConfigure
, you will often be prompted for a password. This post explains why this password exists, how to find it, and what it means for your installation. What is a Grid Code and Why is it Password Protected?
A Grid Code is a set of rules and requirements defined by local utilities to ensure that grid-connected equipment (like your inverter) does not jeopardize the safety or stability of the grid. Safety Requirements: If the grid goes down, your inverter
shut down immediately (anti-islanding) to prevent feeding power back into the grid, which could kill utility workers. Regulatory Compliance:
In many countries (e.g., Australia with AS4777), modifying these settings without authorized personnel is illegal. The Password:
The password is designed to prevent untrained individuals from accidentally changing a setting that could cause a blackout or damage equipment. How to Find the Victron Grid Code Password The grid code password is
a secret, but it is not public knowledge to prevent inadvertent changes. Ask Your Supplier:
The primary, official way to get the password is to contact your Victron distributor or installer. Victron Training: The password is provided during official Victron Professional training courses Online Community:
It is known to exist within online Victron community forums and older training documents (e.g., a common, long-standing, yet unofficial password often referenced is TPWMBU2A4GCC Note on "ZZZ": The password
is the default password for basic VEConfigure settings, but it is the grid code password. How to Configure Grid Codes in VEConfigure Connect your MK3-USB adapter to your VEConfigure Navigate to the "Grid" tab. Select Code:
Select the appropriate country code (e.g., UK G98/G99, Germany VDE, etc.). Enter Password: When asked, enter the grid code password. Send settings to the device. Grid Code Settings for Off-Grid or Generator Use
If your installation is completely off-grid, you may not need a specific grid code. Setting 'None': grid code password victron install
Leaving the grid code as "None" means the inverter will not feed energy back into the grid. Generator Issues:
If a generator trips the inverter due to frequency fluctuations (Loss of Mains/LOM detection), you may need to set the grid code to "Other" or disable LOM, which requires the password. Important Safety Information Disclaimer:
Changing grid settings without proper knowledge can lead to unsafe conditions, grid failure, or the inability to pass inspections. ESS Requirement: Energy Storage Systems , selecting a proper grid code is mandatory. Responsibility:
As the installer of record, you are responsible for the compliance of the setup.

| Error Message | Likely Cause | Fix |
|---------------|---------------|------|
| “Invalid password” (but 00000 was used) | Password was changed previously | Find original installer or contact Victron |
| “Grid code locked – contact support” | Too many failed attempts | Power cycle device, wait 1 hour |
| “No grid codes available” | Firmware too old | Update firmware using VEConfigure 3 |
The Grid Code password is your friend. It provides legal traceability. If a utility inspector asks for proof of compliance, you can show that the inverter is locked to their approved code. If an end-user messes with settings and causes flicker, the password protects you from blame.
Bottom line: If you need to bypass a grid code password because you lost it, treat it as a major process failure. If you need to bypass it to install non-compliant settings, walk away from the job. The grid is not a playground.
