CG generator vs inverter??

Both the inverter and shore power go through an automatic transfer switch, which will switch to shore power when available and default back to the inverter when shore power is cut.  Shouldn't be a problem, though I don't have Oliver's setup so I don't know how much of a delay is involved and if it might be long enough for some electronics to turn themselves off - someone with direct knowledge may want to comment on that.

 

But I'd think that a CPAP would be wired to come back on after a power interruption regardless.

The transfer should be automatic. It takes about 20 seconds for the surge suppressor computer to sample and analyze the incoming current to decide if it is of acceptable quality. Then it will engage the relay with an audible CLUNK, and take over from your inverter. You can shut that off if you like, but it can be left to to run in the background for when the shore power shuts off.

 

The time delay will let any voltage spikes from the generator’s start-up settle down before connecting to your trailer, which is good. Nobody likes spikey voltage....

Thank you. We have a 'portable' Progressive EMS, which should delay any spikes. The CG generator has a timer that turns it on @ 10:00 to 10:30 PM, and 2:00 to 2:30 AM.  Have not had any problems, but sure didn't want to get up to to adjust anything. Guess we are ok as we were. Using the Oliver we never knew if the power was on or off anyway.

Just curious, we run two machines every night (1x CPAP and 1x BiPAP). We run both off 12 volts (via the batteries).  Do your machines not run on native 12 VDC?

It is basically a 12v unit. We just never got the 12 v cord as we seem to have inverters in everything. I suppose the simple thing is to just get a 12 v cord, plug it in and not worry about inverters and such…

 

 

As you know, using an inverter takes our on board 12 VDC, changes it to 120 VAC, into which a wall brick is plugged to convert it back to 12 VDC.  As is obvious, this is a very inefficient way to use a 12 VDC piece of equipment.

 

The 12 VDC plugs for our machines were over $50.00 each and we needed two.  I solved that problem by making my own.  The problem was that the wall converters had a proprietary plug that I could not find/buy.  I went down to my local respiratory care place and asked if they had any old nonworking power supply's.  She brought a box of them out and let me take two for free.  I cut the cords off, put a $3.00 12 VDC male plug on the end and voilà, a (relatively) free power cord.
