Are there any neighborhoods that have electricity all the time from the grid?............Doc..............
I seriously doubt it. At my condo in Cabarete we average 23 hours/day. Some days it's on for the full 24 hours. Other days it might be off for 2-3 hours. We have a planta - so no problem.
And if you are in Cabarete center, you are on an A circuit, but backup is still needed almost every day.
In my area of Santiago we have 24/7 power. I don't even have an inversol let alone planta. My son however lives in the capitol (in a nicer area) and his power goes on and off all day. The building has a planta but it is one of those that do not switch over automatically so it takes a few seconds to switch over.
