More on Surge suppressors
For those doing any grid tied or just generally information on surge suppression and interfacing power stations and modern small appliances, surge suppression is either overlooked, under spent, or misunderstood.
Most surges are "coming from inside the house" as each time a motor starts up a small surge occurs. Motors can be an Air Conditioning compressor, a refrigerator, a table saw, etc. Surges don't destroy sensitive equipment immediately, but over time. Its death by 1000 cuts.
It is recommended to have a quality surge suppressor on the main panel AND individual surge suppressors on sensitive equipment. Sensitive equipment today is almost everything as everything has a microprocessor built into it.
