If your authorised representative in the EU put your products under his/her own name, then she/he takes over your responsibilities. In this case he/she must have sufficient information on the design and production of the product, as he/she will be assuming the legal responsibility when affixing the CE marking.
Many of the larger inverters come with a built in charger. Typically a 2000 Watt or larger inverter will have a 50 to 100 Amp 3 stage charger. These are much better than the typical RV converter/charger. If you are planning on a more powerful charger anyway, the combo units make sense.
Just a reminder, a Converter Charger is only necessary while charging the RV batteries when plugged into shore power or while using the generator. In theory if you have ample solar power and plenty of sun you could ditch your Converter Charger (I would not recommend this as nature doesnât always cooperate).
