I just took a peak at the pictures of your home and your set-up... I'm not laughing at all.Don't laugh, but I am currently living in the Philippines and had to consider my own dedicated transformer, power poles and powerlines for clean power some years ago [not cheap}. To cut a long story short the power company added one much improved transformer and I use a dedicated line from that. It certainly improved the lighting / aircon stability a lot, even the electric fan speed would vary in the past, but not any more.
Your home and garden is just WOW!
