I am experiencing an issue with a Victron Multiplus II GX when selecting the grid code “Spain” or “Europe” Whenever I apply these Grid codes, the unit fails to accept the grid and enters a loop (restarts / grid not accepted). As a consequence, ESS remains in state #3 (“ESS disabled because no valid grid code / grid not accepted”). The system works normally with None Grid code, but then I lose the option to use the battery energy combined together with the grid energy. or use the Dynamic ESS. I is not activating the Batery to feed my installation. I can only activate the inverter manually. To rule out external causes, I have tested the unit in a minimal configuration: - All downstream AC loads disconnected - Only AC-IN connected (L + N) - Protective Earth (PE) correctly connected to the Multiplus PE terminal and bonded to chassis - No external Neutral–Earth bond present anywhere Any idea’? Thanks in advance ---

**“bonded to chassis”** … sounds like a motorhome installation … How is the multi connected? Are L and N the right way round? ---

😉 Sorry.. I meant: Protective Earth (PE) is connected to the Multiplus PE terminal and to the metal chassis, which is connected to the building grounding system. Yes, they (L & N) are right, I have double checked and checked with the Multimeter. ---

No problem… 🙂 What are the voltage values from the mains? Do you have a picture of the GX display… You can easily attach pictures here… Try the German network code… If the multi has already worked… the connection MUST be correct… sorry for asking… ---

Thank you for your help: I also tried the German Grid Code with the same result. I’m thinking in restore to factory settings and start from scratch. Here you have an screenshot with the voltages ![image](https://europe1.discourse-cdn.com/victron/original/3X/0/1/011f9a022304036954c5822a02b586cb2e7d3757.png) ---

Are you configuring with the MK3 …or via VRM? ---

looking goood 👍 Then show us the settings from your ESS assistant. ![grafik](https://europe1.discourse-cdn.com/victron/original/3X/f/1/f19bbc685bbc5a00786869544b7e773671563924.png) ---

To be able to activate the ESS Assistant, I changed to Spain Grid code, then removed the Spain Grid Code and let the other options. ---

ECO-Worthy 48V/5Kw connected with CAN ![image](https://europe1.discourse-cdn.com/victron/original/3X/1/3/137d8928c1565f1ebcd45db03e4359839120385f.png) ---

Then you don’t need the “optimized with battery life” mode… you can set it to… without battery life… since it’s not a lead battery… But you have a single-phase power supply in Spain, right? ---

yes, we have single phase power ---

you could set this to “single phase” ![grafik](https://europe1.discourse-cdn.com/victron/original/3X/2/2/222723e77e5e96ab8097787481d3ba62c0c89aa2.png) Did you have “ESS Errors” yet … and have you all your Loads AFTER the Multi ? ---

ok, I change it. Not yet. I get one in VE.Config when I change from Spain code to None code. related to ESS. just that. Yes, I have all loads in AC-OUT1. AC-OUT2 is empty. Only thing before Multi is a Shelly EM meter. [Next page](https://community.victronenergy.com/t/no-way-to-configure-grid-code-spain-with-victron-multiplus-ii-48v-5kw-gx/50215.md?page=2)
