The micro air works great on my 20-year-old 4-ton HVAC unit 1 Schneider 6848 Pro runs the whole house lithium and batteries of course.

I installed the micro air on a 4 ton scroll compressor and my 6kw growatt with the giant transformer started it but was very close to the Max watts the inverter could do... So I got rid of it and installed the Mr cool universal dc inverter unit.. now it runs so much easier and about 2.5kw to 3kw normally

the 3k growwatt units have an issue with the ground to neutral and some AC's won't run without it. There are fixes online.

my central air unit, which is fairly new uses about 2.4kw to run, but about 16kw to start. this is all new to me so i could be wrong, i measured hot or neutral 240v at the box going to the pump outside, using the inrush setting on my amp clamp. 16kw/2.4kw= 6.66 times. my puny 120v 5kw high frequency psw inverter is not going to get it done

Did I miss what batteries you were using or was it just pulling from your panels?

What state are you in I need some solar panels
