FEATURES
INNOVATIVE DESIGN & PROTOTYPE TESTING are key components of
GENERAC’S success in “IMPROVING POWER BY DESIGN.” But it
doesn’t stop there. Total commitment to component testing, reliability
testing, environmental testing, destruction and life testing, plus testing
to applicable CSA, NEMA, EGSA, and other standards, allows you to
choose GENERAC POWER SYSTEMS with the confidence that these
systems will provide superior performance.
SOLID-STATE, FREQUENCY COMPENSATED VOLTAGE REGULATION.
This state-of-the-art power maximizing regulation system is standard on
all Generac models. It provides optimized FAST RESPONSE to changing
load conditions and MAXIMUM MOTOR STARTING CAPABILITY
by electronically torque-matching the surge loads to the engine. An
unequalled ±1% voltage regulation.
SINGLE SOURCE SERVICE RESPONSE from Generac’s extensive dealer
network provides parts and service know-how for the entire unit, from the
engine to the smallest electronic component.
TEST CRITERIA:

GENERAC TRANSFER SWITCHES. Long life and reliability are
synonymous with GENERAC POWER SYSTEMS. One reason for this
confidence is that the GENERAC product line includes its own transfer
systems and controls for total system compatibility.

RATING: All three phases units are rated at 0.8 power factor. All single phase units are rated at 1.0 power factor. STANDBY RATING: Standby ratings apply to installations served by a
reliable utility source. The standby rating is applicable to varying loads for the duration of a power outage. There is no overload capability for this rating. Ratings are in accordance with
ISO-3046-1. Design and specifications are subject to change without notice.
kW rating is based on LPG Fuel and may derate with natural gas.
