ok, will do. Thanks.

Thanks for all the help and inf everybody. Learned a lot.

  So I figured out what I was doing wrong. I finally checked the hertz with a real gauge and I was getting around 75 at full throttle. Seemed like I had to back the throttle down quit a bit to get down to 63 H or so. To bad there's no tack.

ok, that makes scene. but it does the same thing on single phase

No, everything still works fine.

thanks triple jim and r racing. good info

I have been doing electrical work for years. Always at code. I know what I'm doing. Amps, volts, watts. It's not rocket science. I was a builder for 15 years. The problem is I'm getting 120 on each lug. 240 into panel. The heat pump compressor works fine but the fan does not kick in to push the...

you can use it on the phase only running 2 hots not 3 hots. Thats the same as 1 phase.

thats how I have run the bigger units in the past. Just leave one lug blank. It's the same problem on 1 or 3 phase.

yes, getting 248 from the 1 and 3 lug.

I'm getting 125 out of each lug and 215 when I put the 2 lead from the multi meter on the 2 and 3 lug or any of the 2 lugs. I'm also getting 120volt from the out lets in the house and all of the breakers in the panel.

I'm use 6 gauge 3 wire to a 70 amp breaker. I shut the main off not to back feed the line. red and black hot, white and ground to the neutral lug. The other unit work fine hooked up the same way. I can take some pictures.

Hi, I have it set on 3 phase 208. I also tried it on 1 phase 240. same problem. thanks

Hi, thanks for replying so quickly. I'm getting 120 on all the breaking in the panel. I have a 5kw and in runs everything fine. heat pump fan and the fridge. The other 10k's do also and all off them are putting out 120 from each lug.

I have a few of these sets. When I load test the on the house ever think work fine except with two of them. The stange part is they make 120 volts at the lugs and house gets power but the fridge light does not come on and the fan for the heat pump does not come. The heat pump it's self comes on...
