I decided to use this and only protect camper from the pedestal. I will not put this after then genset.


Thanks to all who added to the discussion.

and this is why it is a good idea for the second poster to quote the OP.

This thread is useless for anyone that may stumble across it in the future.

Sorry for the confusion.

I really see why now, many people choose not to post, rather, just lurk.

Again, sorry to anger.

Thanks again to the people that offered excellent assistance.

What was the question again? Talk about adding to the confusion. You're not worthy, Mr. Obfuscation.

You are under no obligation to "explain yourself" to those people who post things that don't apply.....for whatever reason.

Ignore the chaff and move on.

I think changing the title of the whole thread was really in bad taste though.

I think the OP's feelings got hurt, he's deleted everything he posted in this thread and replaced with ********** or "done" What a useless thread for anyone to learn from, when you don't know the questions.

Not worthy of this individual receiving any answers in the future, if all he's going to do is take, take, take, and not give at all.

And to think he's been here since 2004. :S

And that answer should suffice I would hope.

I'll never forget a public "figure" answering a question about his misconduct with
"It depends on the meaning of the word 'is'"

Was that a Clinton? Deceptive then, still deceptive now.

That oscillation you described is exactly what I had envisioned IF there was no buffer to speak of. That's why i am not wiring it that way.

So if you're not wiring the genset output through the EMS what's the question as posed in your original post - "Here is the question.....How fast is it? I really don't want my A/C causing the genet's output to stop overtime the compressor kicks in." :h

BTW, I presume by "overtime" you meant "every time". :@

As for the EMS having any "buffer" before disconnecting power that's exactly what one would not want when connected to shore power and voltage falls beyond acceptable range.

If I understand correctly you're asking what the EMS-HW30C's shut off response time is? :@ If so, I'd say based on my own unit that's it's "instant" ... yeah I know, not scientific but once voltage crosses either the low or high voltage threshold it shuts off "instantly". If the power source was my genset rather than shore power the moment the A/C compressor kicked on voltage drop would cause the relay inside the EMS to chatter ... solution is to remove the unit from the system when running on genset, ergo the reason I installed mine using 30 amp connectors. As far as surge protection is concerned the unit is spec to react in < 1 nanosecond.

As you're probably aware threshold voltages for the EMS-HW30C are 104 vac low and 132 vac high but that assumes the unit has been correctly calibrated. Mine wasn't but rather was reading almost 2 volts high and the result was it wouldn't shut off at 104 vac but closer to 102 vac ... fortunately the hard wire HW30C, unlike the sealed portable unit, can easily be re-calibrated provided you have a meter of known calibration.

yes, it is instant. it is driven by the pull in and drop out voltage of the relay. as mentioned you have some adjustment range, but at the low end, at some point the relay itself will drop out.

So....... Here is the BIG Problem you may encounter. generator bogs below 104V, relay trips out, generator recovers, relay kicks in, generator bogs, relay kicks out....... you get the picture. It will buzz like crazy and the generator will give fits, and the AC won't start.

That's what I've experienced even when using two honda 2000's in parallel IF they are in eco mode. Out of eco, fine. in eco, they can't recover fast enough to keep voltage above the dropout voltage.
