Yes, there are many different upgrades for a converter. But be prepared, most are bare minimum requirements.
Be very careful and looking into charging profiles and compare them to the batteries you select. Make sure they match. Lithium can be very beneficial. But only if you get the lifespan.
I went with Victron Energy Inverter/Charger. They are completely programmable. Coupled with the battery meter, its almost infallible. Controls the charge rates and perfectly looks after the batteries.
Definitely more expensive than most brands. But worth the peace of mind.
