I'm not understanding the question here. If the purpose of the generator is to assist the generator in charging the batteries, then you don't need to convert the DC solar output to AC, just use both sources to charge the batteries.
x2.
If all they want is some "assist" to generator while charging battery, the simplest way is to run genny first and solar later.
Genny will bring it to 80-90%% quick, and then it will slow down to crawl. This is the nature of battery. Also, battery "likes" being fully charged every day. For this last slow stage you want solar. Depending on your daily energy needs, 235W solar could handle the last 30% or more, i.e. the genny will only need to bring it to 70%.
Running both genny and solar in parallel sounds complicated and not worth it, with mere 235W solar. Grid-tie solar homes is a whole different game, their arrays are typically 2,000W+
