Question:
My 2021 Renegade Verona has a 48V inverter setup and an 18K BTU mini split. Can the Cummins Onan RV Generator QD 8000 CM44RR support both charging and cooling?

Hey Raechel, yes, without a doubt.
With 66.6A of 120V output, this diesel beast is built for exactly this kind of high-demand full-time setup. In Flagstaff and similar high-elevation areas, its turbocharger keeps it from losing power at altitude.
We’ve worked with RVers running residential fridges, mini splits, chargers, and TVs all off the diesel Cummins Onboard RV Generator 8,000 Watts # CM44RR. Plus, its self-diagnostic system makes troubleshooting a breeze if anything ever happens.
How are you liking that Renegade so far? Those are super nice.
