Tengo Victron Multiplus II inversor cargador antiguo y esta actualizado hasta 1949, no me da mas obciones es correcto
I think this looses something in translation.
However, if you are asking about the latest firmware for the multiplus, very old models need VE Flash to update.
I don’t think that Victron are committed to updating these older machines with small processors. The probably don’t have the capacity needed to install all of the newer features.
