Yes, nopAccelerate supports nopCommerce stores with multiple languages. However, it does not support multiple languages on a single store. You need separate store (using multi-store feature of nopCommerce) for each language and a dedicated Solr Core for each store. Moreover, depending on your language you may also need to modify Solr Config file for performing appropriate language analysis.
