Dual Honda 2000s versus AC

Quick background: Using the PI HW-30 hard-wired EMS, I was using 2 Honda 2000s (regular + Companion) in parallel to run my 13,500 btu ac.  When the compressor cycled from Off to On, the EMS threw a low-voltage error code & shut down the power.  This was with the Eco throttles on.  (No problem with the Eco throttles off & the generators running at higher RPM.)

That made no sense to several of us since, in "continuous" mode, have a combined 3600 watts.  What seemed likely was that, when the ac cycled on, there was a momentary pause while the two generators spooled up.  Possible solution: turn the EMS off thereby bypassing it & trust that the Hondas deliver stable power.

The test today showed there is indeed a momentary low-voltage lag, but the generators kept the ac running.  I was monitoring the voltage with a Kill-a-Wat and they went like this:

122.1 - compressor on

125.6 - compressor off 

102.1 - flashed once when compressor came back on

122.4 - compressor on

125.7 - compressor off

101.1 - flashed once when compressor came back on

122.4 - compressor on

Next question:  Can the momentary brown-outs cause any damage to ac, fridge, etc.? I really could use some advice here, as I have -0- skills in this area.

BTW, why don't I just run it with Eco throttles off?  Answer: I may have to, but hope to avoid the extra noise & fuel consumption.

Thanks in advance, gents.

I'll give the bypass a try & report back.  I can use the Kil-A-Wat to monitor for dangerously low voltage while conducting my little "experiment".
