hello team,
One year ago, I installed a solar PV system with batteries in my house. Whenever i start large loads, the inverter doesn't support the surges. At first, I thought the surges were very fast because i have HVAC VFD pumps (it's a villa). After one year, i suffered from the lights in my house that are flickering, and they have also experienced burnouts, as well as a damaged pump. as well the inverter is experiencing overload. I installed a power analyzer, and it turns out there are a lot of harmonics. I am now conducting research on this situation. What are your explanations for this issue?
