The national standard GB/T2820.1-1997 "Reciprocating Internal Combustion Engine Driven Alternator Units" Part 1: Purpose, Rating and Performance Article 7 stipulates four levels of performance for diesel generator units:

1. G1 performance: The requirements apply to connected loads that only need to specify the basic parameters of their voltage and frequency. Mainly used for general purposes, such as lighting and other simple electrical loads.

2. G2 performance: The requirements apply to loads that have the same requirements for voltage characteristics and public power systems. When its load changes, there may be temporary but allowable voltage and frequency deviations. Such as lighting systems, pumps and fans.

3. G3 performance: requirements apply to connection equipment with strict requirements on frequency, voltage and waveform characteristics. Such as radio communications and loads controlled by thyristor rectifiers.

4. G4 performance: It is required to be suitable for loads with strict requirements on frequency, voltage and waveform characteristics. Such as data processing equipment or computer systems.

Therefore, Quark Motor kindly reminds you: When purchasing diesel generator sets, you must first confirm the purpose of use, and choose the diesel generator set with the corresponding performance, so as to maintain the best cost performance and safety of the diesel generator set.
