5. FAQ (Frequently Asked Questions)

Q1: What is the practical difference between prime power and standby power of the SDEC 4HTAA4.3-G21 generator set?

The 80kW/100kVA prime power is the rated continuous power of the unit, designed for long-term full-load uninterrupted operation. It is suitable for daily off-grid main power supply and long-duration continuous power generation for industrial production. The 88kW/110kVA standby power is emergency peak power with a fixed overload margin, only used for short-term emergency power supply during municipal power outages. Long-term full-load operation under standby power is prohibited in daily use. Distinguishing the two power modes strictly can avoid equipment overload aging and sudden failure, effectively extending the overall service life of the generator set.

This unit is professionally calibrated for international 60Hz power frequency standards with a fixed rated speed of 1800RPM, fully matching the power grid voltage, frequency and electrical equipment specifications of all 60Hz countries and regions globally. It adopts IP23 dust and splash proof protection and H-grade high-temperature resistant insulation structure, adapting to complex overseas climates including high temperature, high humidity and heavy dust. With stable heavy-load performance, Euro III compliant emission standards and complete global after-sales support system, it is one of the most cost-effective 100kVA 60Hz export diesel generators for overseas industrial, commercial and residential power projects.

Q3: How to maintain the 4HTAA4.3-G21 generator set to keep stable performance and standard fuel consumption?

The standard full-load fuel consumption of this unit is 25.6L/H. Standardized daily maintenance is essential to maintain stable operating performance and fixed fuel consumption. Users should avoid long-term overload operation and match the operating load reasonably according to actual power demand to reduce invalid fuel consumption and mechanical wear. Regular replacement of diesel filter, oil filter and air filter ensures sufficient fuel combustion and clean air intake, preventing engine carbon deposition and power attenuation. It is necessary to use qualified standard diesel fuel to avoid engine jitter and power instability caused by inferior fuel. Meanwhile, regular inspection of the cooling system and electrical control system ensures good heat dissipation and stable power generation, reducing failure rate and realizing long-term efficient and stable operation.
