5. FAQ (Frequently Asked Questions)

Q1: What is the actual difference between prime power and standby power of the SDEC 6HTAA6.5-G23 genset?

The 150kW/187.5kVA prime power is the rated continuous power, designed for long-term full-load non-stop operation. It is suitable for daily off-grid main power supply and long-duration continuous power generation for industrial production. The 165kW/206kVA standby power is emergency peak power with fixed overload margin, only used for short-term power supply during municipal power outages or sudden load surges. Running long-term full load under standby power will accelerate engine aging and increase failure risk. Distinguishing the two power modes correctly can effectively extend the service life of the high-power generator set.

Q2: Is the SDEC 6HTAA6.5-G23 generator suitable for overseas 60Hz export projects?

This unit is professionally tuned for global 60Hz frequency with 1800RPM fixed speed, fully matching electrical standards of all 60Hz countries and regions.

With reliable six-cylinder turbocharged heavy-load performance and Euro III equivalent emission standards, this 187.5kVA 60Hz export diesel generator is highly suitable for overseas industrial parks, construction projects and commercial supporting power projects, with complete after-sales support system.

Q3: How to maintain the 6HTAA6.5-G23 genset to keep stable performance and standard fuel consumption?

The standard full-load fuel consumption of this unit is 43.4L/H. To maintain stable performance, avoid long-term overload operation and match the load reasonably according to actual power demand. Regularly replace diesel filter, oil filter and air filter to ensure sufficient fuel combustion and clean air intake, preventing engine carbon deposition and power attenuation. Always use qualified standard diesel fuel to avoid power jitter caused by inferior fuel. Inspect the cooling system and electrical control system regularly to ensure good heat dissipation and stable power generation, reducing daily failure rate and maintaining long-term efficient operation.
