Trace 4024 settings

Welcome to the forum Ssbarbich

I don't know about the Trace settings--But the (more or less) most efficient method is to start the genset at the crack of dawn (when needed--like 75% to 50% or lower state of charge) and run your AM loads+battery charging to ~80% state of charge, shutdown the genset and let the sun finish charging the rest of the day.

Monitoring your charging current at 29.x volts--When you start to see the current fall (from "full" charging current from the genset), is usually about the time to shutdown genset (on a clear sunny day). Typically, 2 hours of "absorb" (relatively light discharge cycle) to 6+ hours for deeply cycled battery bank (50% or deeper cycling).

So, what parameters can you adjust for your Generator Auto-Start control?

Does your system of Solar, or are you only using Genset for charging... For the most part, as generators become unloaded (especially for gasoline and propane type), they become less efficient. More or less, your fuel flow at 100% loading is 100% of rated flow (gallons per hour etc.). At 50% or less electrical loading on the genset, the fuel flow tends to drop to 50% and not much lower. And shutting down at lower electrical loading on your genset and letting the solar finish charging will should save you fuel costs.

You want to end your genset charging by 80-90% -- When the battery is not drawing much charging current. Using the genset to get to >90% state of charge every charging cycle "can waste" fuel.
