Just an update on the safety switch... I have learned that the main purpose of it is for fueling up...Onan does not want the generantor to start during this period. So if you did make your own safety switrch keep this in mind.

For those who have instaleld the EC-30, what connection for the 110v-12v conversion has everyone used used for shore power sense?

If I decide to purchase/install the EC-30 I want to be able to have it work whether the inverter is enabled or not. The only 110v source in the "house" that is shoreline-genset only is the fridge and it's hardwired.

It was time to bump the thread anyway.

I believe most people are using a transformer like how a door bell gets it power. It senses shore power and doesnt let the genset to come on. I think under the panel in the bath sink there is an outlet or junction box. I went under the shower to get there to run another wire once. I did not hook it up because I do not set the ec 30 to auto when I am plugged in. I only use it when I dry camp. If you had pets and while you were plugged in and needed the backup gen for the ac or heat while you left or for long periods away for food I could see the reason to hook up the shore power sense wire. Just lazy....Good luck.

In trying to keep the install simple, I used the 110 source for the Engine heater switch that is in the same area. I put a socket in the line and plugged in a 12 volt transformer/charger and tied in to the EC30. Works very well. Of course this only works on a diesel. I had to do this as there is no way to snake any wires to the area without removing some major items.

Did you put that socket in downstream of the enginer heater switch (i.e. so shore power would only be detected if the switch was on)?

The part that bugging me about sensing shore power is if you truly want to sense shore power for real then it has to be independent of the inverter. To me it makes no sense to tap into the junction box, engine block heater circuit (same circuit as the hair dryer and GFC outlet in the bathroom in my floorplan), or any other outlet that has power supplied by the inverter.

To better understand what is exactly is required here I need information which does not appear to be posted in this thread. An electronic copy of the EC-30 installation/user manual would go a long way for me. However, it does not appear to be posted on the Onan web site. All I can find anywhere is the spec sheet. If anyone has a PDF they could post that would be huge.

My biggest questions are:

1. Does the presence of shore power only inhibits auto-start? Does it also cause the generator to shut down when it's already running due to low-battery or HVAC request? The basis of this question is the fact the suggested 110v taps all come live when the generator is running (i.e. could be self-defeating).

2. Does the presence of shore power prevent auto-start even if the battery is low?

Thanks.

No, The socket was installed on the live side.
The unfortunate part is that this line is also supplied by the inverter.

HERE IS MY 2 CENTS.

Shore power prohibits the onan from starting when you are on shore power.

It does not shut down the onan when the ac is already on...each wire to the onan ec 30 has a specific function. If the thermo does not need power to run the ac or heat it tells the ec 30 to shut down.

When gen starts in auto mode the ec 30 will run the gen fo a min of 10 minutes. even if the call for ec 30 is no longer present such as thermo, batteries, etc...it is a safety to prevent quick excessive start and stops.

as for ac power make sure whatever you use for ac shore power sense always comes live when you plug in to shore power and not on a switch or 3 way switch etc. or only live with the inverter on.

As for the manual please email me and I will scan to you. fpd257@rcn.com

So it sounds like it's OK for the 'shore power sense' to be active when either shore power is connected or the generator is running, since it will inhibit starting the generator but will not stop the generator once it's running. That would imply that any 120V circuit that's not on the inverter would be OK. Is that correct?

Gary,

Nice install; very professional (I inspected it personally!!!).

Gary,

Very nice. Unfortunately in my case I don't have the room above my One-Place to move the water heater and engine block heater switches.

1. The genset will run a minimum cycle time (i.e. 10 minutes or whatever the current adaptive value is) even if shore power comes on.

2. The EC-30 will not shut down the generator when shore power comes if there is a current HVAC request in process. When the HVAC request is completed then it will shut down the generator (assuming condition #1 has been met).

Under all other conditions, including low-battery, it will shut down when shore power comes on if minimum cycle time requirements are met.

My take shore power is difficult to set up for real as there is no direct source to tap before the transfer switch and/or inverter. As such my approach will be to use a 12v transformer on a 110v outlet internally and either unplug it or set up an in-line switch when I want to defeat shore power sense function (i.e. when boondocking). I will combine this with turning the inverter off when I'm really connected to shore power. A little complicated but all the way around this seems to met most of the possible scenarios one would encounter.

And for what it's worth I'm planning on using the stop side of the old generator switch (which I wont' be removing) as my safety switch. I'll configure the EC-30 safety detect option for brake-light mode.
