Hello everyone, I have an EasySolar-II GX installed in a converted truck. At the moment, I’m parked on a plot of land with access to the grid, but about 1,200 meters away from the main electricity meter (the cable size and distribution panels were designed for this distance). I wanted to test the ESS assistant without grid feed-in. To do that, I had to enter the country code (Grid), and since then I’ve been getting Error 11 – Grid relay test failed. I can no longer connect to the grid. It’s impossible to change this parameter again, even after removing the assistant. I even tried to restore an old configuration file (.vsc) via VRM, but I keep getting the missing password message. I really need to remove this setting, especially since I travel between different countries with my vehicle. I don’t actually need the assistant — I only wanted to test it to see how it behaved, as I was planning to stay in one place for about six months. Thanks in advance for your help! If anyone has encountered this issue after adding a country code, I’d really appreciate any advice on how to properly disable it. ---

You can’t get a password from your Victron supplier to change the grid code? ---

If that’s the only solution, I’ll call them tomorrow, but they’re just resellers, not installers. ---

I can’t give details but if that fails: 1. Sign up at [professional.victronenergy.com](http://professional.victronenergy.com), watch a video, and get the password. 2. Or cleverly (not here) Google for a password. Not recommended but sometimes, you must close your eyes and do what must be done. Remember philosophically, if nobody saw anything, you didn’t do it 😜 ---

FYI [error 11](https://www.victronenergy.com/live/ve.bus:ve.bus_error_codes#error_11_-_relay_test_fault_-_installation_error_or_possibly_relay_failure) is a wiring fault related code. So something there doesn’t meet code. But yeah being a in a truck means you don’t meet a grid standard mobile installs are usually done a little differently in terms of grounding and bonding. ESS should [not be used in mobile installs.](https://www.victronenergy.com/media/pg/Energy_Storage_System/en/ess-introduction---features.html#UUID-b26ba3e6-708a-268b-66bc-2681a9c4ea78) > **Summary** > > ![IMG_20251112_140144](https://europe1.discourse-cdn.com/victron/original/3X/b/0/b0adfcb467ea0f4969cdb8f811bf9ae131a32476.jpeg) There is another option that is _[solar wind priority](https://www.victronenergy.com/media/pg/Solar_&_Wind_Priority/en/index-en.html)_.
