No more worries of blackouts, brownouts or weather related outages. Just peace of mind that 24 hours a day, 7 days a week your home and family are protected against electrical failure.  No lights, loss of communication and safety issues are just a few of the headaches associated with a power outage.  When the power goes out, depend on GUARDIAN Home  Standby generators to supply automatic back-up power  even when you’re not there.

• Fully automatic 
• Permanently installed 
• Runs off home's fuel supply   (Natural gas or LP)
• More practical than a portable

ATS

The completely automatic Guardian transfer switch monitors incoming voltage from the utility line - around the clock.   When utility power is interrupted, the automatic transfer switch immediately senses the problem and signals the generator to start. The automatic transfer switch then safely closes off the utility line and simultaneously opens a new power line from the generator.  Within seconds, your Guardian generator system begins supplying electricity to the critical emergency circuits of your home or business. The transfer switch continues to monitor the utility line conditions.  When the automatic transfer switch senses the utility line voltage has returned at a steady state, it re-transfers the electrical load back to the utility line and resumes monitoring for subsequent utility loss. The generator will continue to run for an engine cool-down period of several minutes while the entire system stands ready for the next power outage.

New: Power. 
Motor starting capabilities. 
& Sound levels.

·        Breakthrough design: the new QuietSource™ 16 kW with the improved Generac 990cc OHVI® Industrial engine and upgraded alternator will start a 5 ton air conditioning unit (or two 4-tons) – even with a 7,000 auxiliary load at less than $4,000. No other air-cooled comes close.

·        Our patent pending Whisper-Test™ feature makes the quietest air-cooled model on the market with weekly exercise sound levels half as loud or less than competitive models.

·        We listened and heard very clearly of the need of a commercial line of generators so we introduced the GUARDIAN Elite series. Liquid-cooled models from 20 to 150kW with single and three phase voltage.

·        Our popular aluminum (optional) enclosures are a great fit for coastal areas where the corrosion-resistant metal will help prolong the look of the unit.

·        GUARDIAN® has the most powerful and broadest line up of generators. From 7kW up to 150 kW.

For whole-house protection



GUARDIAN offers air-cooled  and liquid cooled

models ranging from 16 - 45kW (single phase) 

and the commercial models ranging from

 20-150kW (single and three phase voltages.) 

Match these generators with an appropriate size 

transfer switch.  Find appropriate Transfer Switch sizes.

To get accurate sizing requirements of a liquid-cooled 

generator, a licensed electrician will need to apply an amp 

meter to the circuits and appliances that are intended 

to operate on backup power. Many customers want

every item in their home or business covered

in the event of an outage. 

Guardian Plus Pre-Packaged Specifications

Continuous Standby Power Rating Includes a 
2 Year Limited Warranty

OPTIONAL LOAD SHEDDING

To save on costs, you can offer your customer a smaller generator coupled with the PowerMasterTM load management system. The new priority load control system makes whole-house coverage more affordable and power hungry items a priority. Your air conditioning will start as the electricity from non-essential items is diverted. This means you can buy a smaller, less expensive generator and still run everything in your home or business. The PowerMaster can control two major loads up to 30 Amps at 240 volts each.

A Word on the Standby Power Systems Market:  

Power outages are becoming more frequent and are lasting longer.  There are two major reasons for this trend.  First, severe weather patterns such as thunderstorms, hurricanes, flood and ice storms have increased dramatiy over the past few years and are expected to continue at current or even greater levels for the foreseeable future.

In addition, the demand for electricity is increasing at an unprecedented rate and power companies are not able to replace aging transmission networks and build new plants fast enough to keep pace with the growing need.
