Thanks for your Electrical Question Peter.

Surge Protection for an Off-Grid System

Surge Protection for an Off-Grid System – electronic circuitry can be damaged if the voltage from the generator is not stable. This happened to us a few winters ago while on generator because the refrigerator and the septic pump turned on at the same time and created a power surge that burned up a surge protector that was installed for a computer.

    I have ordered an 8kw solar panel system. It is a DC system which I plan on installing a battery back at some point in the future for islanding. I recently won a free whole house surge protector which will be installed before my solar panels. Problem is, I don’t know where in the system the surge protector should be installed? Before or after the solar panel Equipment?

  2. Dave Rongey says:

    Hi Adam,
    Congratulations on the whole house surge protector. The point where the installation of the surge protector will be installed will depend on the voltage that the unit is designed. Since it is a whole house surge protector it may be best to install it at the main panel of the home circuits. Be sure to consult the installation manual for complete details. As for the solar panel system, make sure the installation is well grounded and bonded.
    Enjoy your islanding – (that sounds like life as it is meant to be). Be sure to share your experiences as you are able. I will be working more with another site that I have ( ) which will be a place to share life thoughts and experiences, it would be good to hear from you there.
