Looks like there are about a half a dozen flavors of 50A surge protectors from PI and Hughes ranging from $150 to $300. I do not speak electrical. What's the difference? I'd like to get one for our new FW - it's 50A but I don't want to spend $300 when I can spend $150.
Some do surge only--which is not really useful.
Some do energy management and do a disconnect if the voltage becomes too low (103.5 volts iirc, which is too low for my comfort zone).
If you believe that the device is needed--buy the top of the line.
