Guardian Series 8kw

[two_col_75_25_col1]

Provides essential circuit power protection for your home, ensuring the necessities remain powered during an outage. The most affordable automatic standby generator on the market offers protection for half the cost of central air conditioning.

Easiest installation on the market and an excellent value when purchased pre-packaged with a pre-wired transfer switch, or customize your system by purchasing the generator and transfer switch separately. Composite pad is included, eliminating the need to pour a concrete base.

Simple field conversion from LP to natural gas.

Generac’s OHVI™ engine was designed specifically for generators. It outruns competitive generator engines with an engine life that is three to four times longer and has a significantly longer period between scheduled maintenance checkups.

Sturdy, galvanneal steel enclosure with RhinoCoat™ finish for superior weather protection.

Electronic Controller and user-friendly LED display and controls for programmable diagnostics and information at-a-glance. Sophisticated codes alert you to generator status at all times.

Added Sound Reduction with enclosures that are lined with sound reducing foam panels for further noise reduction.
