Electrical engineer needed

[Brad Townsend]

This past summer I think my shore power cooked my Engel freezer. The voltage at the pole was 108 volts, not good i know, When I put a load on such as elect heater ac or stove it would go as low as 90 volts. I also have had to replace a 32" Phillips tv, Macbook laptop,
and the mid AC units compressor would not come on. Now at a new site on 220 volt the mid AC will run, thought the compressor was fried. What I would like to know is What takes place with low ac voltage and can low ac voltage hurt something like a laptop which runs on probably 18 volts. Can the Hertz change with low voltage? The freezer was 4 yrs old, Engel sent me another compressor which is basically all the inards as it is a sealed unit for $350 and thought it was odd that the compressor went out as they are a world class unit good for eons. The 110 line was on a 30 amp breaker but I would pop it around 20-25 amp draw according to the gages in the coach. I will probably go back to the same site next year and would like to go to the powers that be with some knowledgeable info as ammunition to get this rectified.

Thanks for your time.
