Hymmmm
We did not turn on the water heater......
Converter?
Fridge is on auto, so it could switch to electrical.....
I can try that, but I really thought 4000 units would /could handle one AC

4,000 watts is really 3,200 watts. Each generator is rated at 1,600 watts continuous load.
You need to make sure the high wattage devices like the refer and water heater are not in the electric mode. You must manually set both to gas mode.

At that point, the generators switch off into red light.....overload alarm.

Suggestions, guidance ,
And yes, triple checked the polarity black L red R 30 amp receiver in my companion unit. Eco throttle off.

Thank you!!!!!!!
Check your thermostat. Make sure one of the A/C is turned OFF.

Don't forget that these ratings are at the industry standard of 90 deg. F. As the outside ambient temperature increases, so will the load requirements for running the compressor.

Also turn the eco-throttle to full throttle on the Hondas to start AC.

Thank you to those that replied!
We manually turned off the water heater and put the refrigerator on gas.
We made sure everything was off, but zone 2, and it turned on for 15 secs and then turned off with error code E7 :-(
I guess back to the dealer to check out the AC. We should be able to run one of the units with 2 of the Honda 2000i's in parallel .

The 2 Hondas should run either of your air conditioners.
If there are no other loads in your trailer, then there must be a problem with the parallel setup. Are both Hondas showing a red overload light?

E 7 code

in another post with the same results E 7 code would not allow AC from shore power. Any way check the 120 breakers and the use or store switch should be in the use position. Lets know

I run them in econ mode to power the AC.

E7 code means the circuit board is not receiving 120V power

i hate to ask this question but here it goes. do you know if your thermostat is in sink to your ac units? If the ac units have been replaced and or your thermostat there is a mfg code to sink between the thermostat and the ac unit. just asking!

I would think Econ mode would not be beneficial in trying to run an ac unit.

A Dometic 13,500 BTU A/C unit has a transient starting load of around 50 amps. Your 20 amp circuits and their breakers are designed to handle a transient starting load such as this, but your generators are not. ECO mode will not suit you well when operating a roof A/C

E-7, as stated above, means that you are not getting 120VAC power to your roof units. A CCC-II thermostat will not show E-7 unless it is not getting the proper signal from the upper control board where the 120VAC enters the upper unit There could be several reasons for this:

do you have 120VAC power anywhere else in the trailer when on shore power, like at the microwave?
*have you checked the breakers by first pushing them down 'click' to re-set and then up 'click' to the ON position?
in reference to the first point, do you have a 'generator inlet' at the front of the trailer? If so and you are not getting power to one of both A/C units, you might have a problem with your transfer switch
if you are not skilled with using a volt meter in an open breaker box.....DO NOT ATTEMPT THIS!!!! You can remove the breaker face plate and check both incoming legs of your 50 amp service at the main tandem breaker to be certain that you are getting power into the trailer. Then check again at the individual 20 amp A/C breakers. Then again at the K-5 relay that is located on your upper control board. This will allow you to follow the path of the 120VAC from the main breaker right into the control board. You can also use a non-contact inductive circuit tester (looks like a small, fat pen and is available at the big box stores) to see of you are getting voltage at the positions described above.

AGAIN, IF YOU ARE NOT FAMILIAR OR COMFORTABLE WITH WORKING AROUND LIVE CIRCUITS....DO NOT ATTEMPT ANY OF THIS AND CALL A REPUTABLE RV TECH
