Generac 70771 – Frequently Asked Questions

1) Is the Generac 70771 standby generator single phase or three phase?
Three phase. The 70771 is rated 120/208 volts, which is the 3-phase wye service you find in small commercial buildings, not the 120/240 single-phase service on a house. If your panel is 120/240 single phase, this is the wrong unit and you want a single-phase air-cooled Generac in the same kW range instead.
2) Does the Generac 70771 come with a transfer switch?
No. The 70771 ships as the generator only, so you order the automatic transfer switch separately and size it to the service. Budget that into the job along with the pad, the gas line and the battery.
3) What amperage does the Generac 70771 put out at 208V three phase?
Output runs 59 to 69.4 amps across its rating, at 120/208V three phase, from 20,000 watts rated output. That current range is what your transfer switch and feeder conductors get sized from.
4) How much room do I need for the Generac 70771 generator pad?
The unit itself measures 48 inches deep, 29 inches high and 25 inches wide, so the pad needs to take that footprint plus whatever clearance your local code requires from windows, doors and the lot line. Shipping crate is larger at 50 by 27 by 44 inches, which matters for getting it through a gate or down a side yard.
5) How heavy is the Generac 70771 and can two people set it?
466 pounds assembled, 525 pounds as shipped. That is not a two-man carry. Plan on a lift gate at delivery and a pallet jack, appliance dolly or a couple of pipe rollers to walk it onto the pad.
6) Is the Generac 70771 standby generator UL listed for a commercial install?
UL Listed, ETL Listed and CSA Certified, which covers the listing paperwork an inspector or a facility spec normally asks for on a permanent standby set. It also carries a California Proposition 65 warning requirement, worth knowing if you are shipping into California.
7) Will the Generac 70771 enclosure hold up outdoors near the coast?
The enclosure is all aluminum with Generac's RhinoCoat powder-coated finish, so it does not rust the way a steel enclosure does in salt air or on a wet roof deck. Color is bisque, which is what the other Generac air-cooled units in the same family wear, so a fleet of them across a property matches.
8) Can the Generac 70771 run sensitive electronics like elevator controls or IT gear?
Generac rates the 70771 under True Power Technology at less than 5 percent total harmonic distortion, which is the threshold usually written into specs for sensitive electronic loads. Clean enough for variable frequency drives, network gear and medical or lab equipment on the standby side.
9) Can I monitor the Generac 70771 remotely across multiple properties?
Yes, through Mobile Link remote monitoring, which reports operating status and maintenance alerts to a phone, tablet or PC. For a property manager running generators at several buildings, that is how you catch a failed weekly exercise without a site visit. On the unit itself the Evolution controller gives a multilingual LCD with battery status and maintenance intervals.
10) What does 20/17 kW mean on the Generac 70771?
Two fuel ratings. The 70771 makes 20 kW on one fuel and 17 kW on the other, the usual split between natural gas and LP on an air-cooled standby set. Size your load calculation against the fuel you will actually pipe to it, and use the 59 to 69.4 amp range at 120/208 for the conductor and switch sizing.
11) Is the Generac 70771 quiet enough for a weekly test near tenant windows?
Its Quiet-Test self-test mode drops the engine to a lower RPM for a five or twelve minute exercise cycle, which is markedly quieter than a full-speed test and burns less fuel. Generac lists that mode on the 16 to 22 kW air-cooled units, and the 70771 sits in that band at 20 kW.
