External NS Protectio - but which one?

Hello there,

im currently using the victrom Multiplus 12 / 800 / 35. I wanted to use it at my trip to Italy in my caravan.

Unfortunately i cannot use my multiplus without getting a error message.

It says, that i need an external NS Protection. If i understood it correctly, my Mulitplus does not a internal NS Protection, otherwise as the multiplus 2.

Could you please tell me, which options i have to run the system at my trip to italy?

Which devices could function as an external NS Protection. Is there any workaround for this?

The devices i found where very expensive and pretty big and heavy. Is there any cheaper solution to this problem? Maybe some devices i could install directly into my caravan?

Thank you in advance for your help!

Best regards

ESS is not for mobile systems and for a normal caravan installation you don’t need a NS protection.
