Howdy! I’ve got a coach with dual Trace sw4024mc inverters. In this TX heat my basement AC’s are pulling enough amps to trip breakers when my inverters are actively charging the battery bank. They’re 20 years old, so every amp counts it seems. These inverters can’t be put on a timer in the setup menu (Trace just confirmed this). So my question: on my control panel inside there’s a “batt chgr” button. Doesn’t seem to do anything. Is it supposed to cut off the charging ability from the inverters to batteries via a solenoid or someth? Any ideas?
