Review on 9000W Split Phase Power Inverter by Julio Roberts
Good while working
The first test was last Sunday. I ran the window air conditioner at 5000 BTUs for 45 minutes and the fan never kicked on and there was no noticeable heat at all. The batteries only dropped 0.3 volts during the test. My device is 48 volts and I have a lot of batteries
Pros
- 1. Hz selection (50Hz, 60Hz, auto selection) Press and hold the button for 2 seconds, the device says Hz is switched, release the button after 2 seconds when you hear 2 beeps, then the frequency selection is successful.
Cons
- Out of fashion
