ALLOY

I met a guy that used a flame to find a leak on his BBQ 3 months after he found it.  His eyelashes and most of his hair had grown back but one of eyebrows was missing and his nose, cheeks and forehead were spotted with dark brown skin. Luckily his glasses saved his eyes.

Edit: I use soap/water but I've found a leak detector liquid works better because the bubbles hang around longer. 

Wanted to thank everyone for posting this information. 

I really appreciate it, Thank You

Thanks Chad

I've had a box of 120v switching breakers lying around for 10+ years.....I finally have a use for them.

In out case we have a 300w (3w standby) and would adds a 3000w. The 300w so the family (Dad like his 60" TV) can watch a movie before going to bed.

I had the thought of using a battery switch set up as  Inverter 1 - OFF -  Inverter 2  with the output from both inverters feeding  the 110v panel. The feed from both inverters would be live when there is any 110v in the trailer.  The panel in ours is up in a bedroom cabinet so switching circuits on and off would be O.K. What I like about the system you designed is one doesn't have to remember to turn breakers on/off.

Our PD transfer switch hums. Tried to tighten things up to no avail. I assumed the AC (wish it was DC) coil that is energized to  keep the contact closed. What switch are you using?

Once again I really appreciated all the information you posted, Thank You

I didn't add the second inverter because I was worried about the "idle" draw of the 3012.  I did it for two reasons.  The primary reason was for use while on the road.  I do not want all my electronics (TV's, satellite boxes, stereos, dishwasher, clothes washer, microwave, etc.) powered while my rig is bouncing down the highway.  I see no reason to take the chance of creating an issue with sensitive items in a moving environment.  I am probably being overly cautious on this, but this is my primary reason.  My secondary reason was as a back up to keep the fridge running in boondocking situations where I was trying to conserve as much energy as possible.  For example, multiple days in a row of cloud covered, rainy days where the solar isn't going to be able to keep up with high electrical usage.  In these situations, if I am not using any other 120 volt appliances, why power them with the big inverter when all I really need to do is keep the refrigerator running.  I can turn the big inverter off and use the small inverter to help conserve energy and minimize generator run time.  I kind of look at like my last trailer with the RV type fridge that I would switch to propane and only turn the whole house inverter on when I actually needed it (not exactly the same circumstances, but similar).  Again, I am probably being overly conservative here, but I figured I was building a system from scratch so why not do it the way I wanted to do it.  It also didn't hurt that I was able to source the small inverter for about half price, so why not.

Hi

You put allot of though into this system.

I like the idea of the second inverter.

I'd like to ask 2 questions.

Was throwing the breakers in the panel to isolate the fridge a consideration?

On standby there is a 1.2A @ 12v difference between the standby draw of the 1012 and the 3012. If my (old) brain recalls correctly you have a transfer switch between the 2 inverters that will draw power?  When designing a system for myself I'm wondering how closely I should pay attention to ghost loads. 

Thank You
