I have a setup as described above with a Quattro 48/5000/70-100/10 inverter. I've connected various servers on the AC loads end.
Every now and then, when we lose grid power, our servers restart automatically, and then it works fine for the rest of the time. While reviewing the datasheet, I noticed it emphasizes the no-break functionality. The problem occurs approximately once every two weeks. How can I pinpoint the exact issue?
You will notice the switch over time is less than 20ms. Most servers need under 10ms. So they have ups function but are not the same as a certified ups. Usually for critical applications we have short duration ups on the servers.
What maybe happening is the grid is going out at zero point in the sine wave. So may possibly explain the intermittent restart.
How tight do you have the voltage range? And the ups function is checked? How else is it programmed.
