Honda 2k works fine for me
I run my Mermaid 12k with my Honda EU2000 without any problems. The factory supplied Mermaid electrical control box sequences the startup of the pump, blower (fan) and compressor. The pump and fan are started first, then after approximately 5 seconds, the compressor starts. The generator does have a hard time coming up to speed if I have the Eco switch on when the compressor kicks in. I usually turn the Eco function off when running the AC.
