7. Should I use the Parallel Threshold feature Depends on the application Most applications set a threshold level such that the connected slave inverters come on only when required to power the loads This reduces the power drain on the batteries because the slave inverters that are not actively powering the loads are in standby However if you have a load larger than the capacity of the master inverter and the startup current is needed very quickly you may need to turn off the threshold setting This would ensure that all stacked inverters are always on to meet the fast startup current requirements of a large load Where should I set the Parallel Threshold Depends on your typical AC loads and how much time you want the master inverter to run versus the slaves If you want the master inverter to run as much of the loads as possible before the slave s turn on then set the threshold at a higher setting If you want the slave s to share more of the load then set the threshold to a lower setting Page 44 2015 Sensata Technologies Using AC Coupling 5 0 Using the MS PAE Series in an AC Coupled Application This section covers the use of MS PAE Series inverter chargers in an AC coupled system 5 1 What is an AC Coupled System Many homeowners utilize renewable energy e g PV wind etc by installing high efficiency battery less grid tie inverter systems to offset their power consumption from the utility grid However during a utilit
