devices for surge protection
Hi, If I add a MOV type device in parallel to the shore power cord will it offer some down stream protection to my RV?

Hi wa8yxm,
But the PI top of the line unit apparently ONLY uses mov technology. I can't imagine them using more in the bottom of the line unit. Please correct me if I'm wrong (I learn new things that way).
I'm not happy with either companies low voltage cut out. SG is 102 and PI 104 volts. My comfort zone is 108 and no lower than 107. Plus the autoformer deals with low voltage quite effectively.
I find low voltage endemic at campgrounds and often at private homes.
High voltage is pretty rare and the Sola basic does offer some protection up to 155 volts. I'm not sure what happens above that as the testing unit I used topped out at 133 volts (input to Sola)
PI does have that lifetime warranty which is a great selling point.

Ok, Surge protection 101
THere are two types of "Surge Guards" one really is.
FIrst there are assorted MOV types. The common six outlet "Surge Protector" you find in stores all voer the place is this kind of device, The low cost one from Progressive INdustries is this king of device.. Hughes Autoformers contain them and I see several suggestions for them above.. These are NOT SURGE GUARDS. they are spike supressors (A spike typically lasts less than 1/50th of a second)
A Surge can last for several seconds and if that happens.. Well, let me put it this way. I had close to a dozen of those things scattered about when the power company screwed up and sent me at least double the proper voltage (A Major Surge) and it sounded a bit like the annual fireworks celebration in that room as they went off like firecrackers, all destroyed, Lost a motor, a computer power supply and all my "Surge Strips"
A true Surge Guard such as the Progressive industries HW-50c (or 30c Or the PT-50/30C) senses high voltage (or low voltage) and cuts off power to your RV, thus protecting Motors (A/C) heat elements (Fridge and water heater) and all sorts of electronics (Converter, TV, Microwave, Control boards, Sat receivers, Radios and so on) Highly recommended
I like the HW models cause they are Hard wired and thus you do not forget them.
