Inverter coolant temp under engine loads

Is getting a boost in inverter coolant temperature during load on the engine normal?

I started monitoring my inverter coolant temp in the intense heat recently and noticed it'll get a pretty nice boost whenever I give the car an initial load, like leaving a stop, then it'll settle back down. Let's say in 95F weather the inverter coolant temp will be 120F then when I give some decent load it'll go as high as 145F for a few seconds before settling back down.

I used to monitor it all the time with Hybrid Assistant and I don't remember it ever varying that much at all, but it's been a while.

 

While responding to a different thread I just discovered that I was actually monitoring 'inverter MG1 temp' instead of 'inverter coolant temp'. I was using custom PIDS so I must have got my wires crossed. Inverter MG1 temp must measure something in the inverter itself because it's different than the actual MG1 temp, usually settles to around the inverter coolant temp, and increases with engine load. Inverter coolant temp does not react to engine load much at all. I was getting worried since I'd seen the temp in the 150's (F) a few times and was under the impression the light would come on at 149F.
