Converter on Low AC Input Example
Converter specs say 105v minimum to work right. On 15a long extension cord from house, running 75 amp converter on low batteries, was getting 56 amps as constant amps instead of 75. Voltmeter said...

Don't have EMS. The 99.8v was loaded voltage of course. Does the EMS kick in from unloaded or wait till load comes on and kill that?
An EMS will disconnect whenever it sees source voltage drop below it's preset low voltage threshold (102 vac for TRC, 104 vac for Progressive). If there's no load on the circuit then obviously incoming source voltage will be higher than if the circuit is heavily loaded, especially when powering through excessively long cable or of insufficient gauge. Regardless, when incoming source voltage drops below threshold either because it's simply too low unloaded or because it's forced below threshold from a heavy load the EMS will disconnect power to the rig to protect any electrical devices downstream of it from being destroyed. That's it's purpose in life. It's either that or an autoformer that will detect excessively low voltage and boost it so it's not excessively low.
