On-Grid Solar inverter - power convertion and MPPT issue

[Prince Vegeta]

A brief discussion of PWM modulation methods can be found in this thread. Please notice the literature links given by bigdogguru. Bipolar modulation is alos referred as 2-level PWM and unipolar as 3-level PWM.

ATS is a topic for emergency power supply rather than grid-tied inverters. I guess a confusion of terms regarding "on-grid inverter".

we wanted to implement the ATS in the solar inverter to check solar power and when it's voltage is low, ATS will switch to the normal grid voltage. u understand this?

I understand that the term "on-grid inverter" doesn't describe the application correctly.
