I was today years old. Thank you for this video. I have units with 506V coming in and it’s too much sometimes for the inverter and it shuts down. Power company said it’s within its limits so it is what it is. Now I can get these and not have anymore call backs.
So you install one transformer to convert all the power or you need to install one per outlet/appliance? What if I need to step up multiple outlets in my commercial kitchen?
It's a questionable design. It varies from State to State but the commonly allowed variance from nominal voltage is +/- 5%. Nominal voltage is 240 (not 230 as mentioned in the video). That means in many States the equipment maximum of 253V is only 1V over the allowed maximum voltage of 252V. That isn't much of a buffer and it begs the question; What the hell what the engineer who designed this thinking? The fact that HVAC School is experiencing voltage readings in excess of +5%, including large voltage swings, suggests the the power company is having difficulty controlling the grid. Edit: I'm an Electrician not HVAC and I'm not familiar with Florida's rules for power companies.
@@arazusaysbah6784here in the Pacific Northwest I have seen residential 240 as low as 207 and as high as 256. Not sure what caused the 207 situation but most solar systems need to produce a higher voltage to backfeed onto the grid and when the power company is supplying 250 then people’s solar voltage has to be increased so they get their credits. My city is wanting to do away with natural gas and the power company went to the council meetings urging the city not to push it too quickly because they are already having a hard time meeting the current demand, but we are pushing it anyways.
I’ve installed surge protectors to prevent damage to the board in these situations. This is another handy piece of equipment to have in your arsenal though for situations where it’s constantly supplying too high of voltage
Nice idea...condenser manufacturers should include one built in with each condenser. Then there are those expensive soft start boxes to save compressors etc.

Appreciate you guys making all this videos for us technicians on the field thank you
I installed one of these for a Bosch unit that was having the same problem. Line voltage coming in at 253 and secondary was almost 30 volts

Yall are awesome.
Looks like NM cable used as a feeder outside?
Add some hvac surge protectors as well
I have yet to see this on any unit. If the inverter cannot handle the line voltage why the heck did they design it?

Very nice
They're very common in India. We call them Stabilizers

That CU looks a little close to the gas regulator, by a few inches i'm sure....................
The DC bus is what has the issue.
I like the name , Buck and boost .😂
Why are inverters used on condenser unit?
Yeehaw
Do you like this better than the ICM493
Communication issues pertaining to infinity and evolution systems?
Yes
