Hi Damon,
Yes, designing a purely off-grid hybrid PV/Generator system without batteries, while incorporating the SMA Fuel Saver Controller as an energy management system, can be done. PVSol may have some limitations in modeling such a specific setup, especially when it comes to real-time energy management without batteries, but it's worth exploring its capabilities. For more detailed guidance and expert advice, you may want to check with or ask directly from Force-V, as they specialize in advanced PV and energy management systems.
Best regards
