VAC dropout setting is that smaller generators or large generators with an unstable output may nuisance transfer This commonly happens when powering loads that are larger than the generator can handle causing the generator s output voltage to constantly fall below the inverter s input VAC dropout threshold Info When switching from Inverter mode to Standby mode the inverter waits approximately 15 seconds to ensure the AC source is stable before transferring 3 5 Battery Temperature Sensor Operation The plug in Battery Temperature Sensor BTS is used to determine the battery temperature around the batteries This information allows the multi stage battery charger to automatically adjust the battery charge voltages for optimum charging performance and longer battery life When the BTS is installed if the temperature around the BTS is below 77 F 25 C the absorb and float charge voltage increases and if the temperature around the BTS is higher than 77 F 25 C the absorb and float charge voltage decreases See Figure 3 4 to determine how much the charge voltage changes increases or decreases depending on the temperature reading of the BTS For example the nominal absorb charge voltage for a flooded battery at 77 F 25 C on a 24 volt model is 29 2 VDC If the battery temperature is 95 F 35 C the absorb charge voltage would decrease to 28 6 VDC 29 2 VDC 0 6 change If the temperature sensor is NOT installed the charge
