The Guardian Series automatic standby generators are designed to be a back up to utility power. Provided the unit is installed at a location with utility power, the generator can function as designed as long as the solar electric power will be isolated in the event of a utility outage. Isolating the solar electric power means that the power provided from this source is unable to feed into the home during an outage or during times where the generator is in operation and providing power to the home. If the solar electric power source is not isolated during a utility outage, it can either back feed into the generator – which could cause damage and void the factory warranty - or it can cause the generator to run improperly, as it can see the supply of power from the solar electric power source. Prior to purchasing, you may want to speak to a Generac Certified Dealer or your local certified electrician to ensure that this type of isolation is possible with your existing set up.

. We as the manufacturer are unable to recommend methods to achieve this isolation, as each installation will vary.
