5. FAQ (Frequently Asked Questions)
Q1: What is the actual usage difference between prime power and standby power of the SDEC 4HT4.3-G23 generator set?
The 68kW/85kVA prime power is the rated continuous power of the unit, which supports long-term full-load uninterrupted operation and is suitable for daily off-grid main power supply and long-duration continuous power generation. The 75kW/94kVA standby power is emergency peak power with a 10% overload margin, specially designed for short-term emergency power supply during municipal power outages. It cannot maintain long-term full-load operation in daily use. Users must strictly distinguish usage scenarios: take prime power as the standard for continuous power generation, and standby power only for instantaneous emergency power supply, so as to avoid equipment overload aging and failure, and extend the overall service life of the generator set.

Q3: How to maintain the 4HT4.3-G23 generator set to keep stable performance and standard fuel consumption?
The standard full-load fuel consumption of this unit is 21.6L/H. Scientific and standardized daily maintenance can effectively maintain its stable operating state and fixed fuel consumption level. First, avoid long-term overload operation and reasonably match the load according to actual power demand to reduce invalid fuel consumption and mechanical wear. Second, replace diesel filter, oil filter and air filter regularly to ensure sufficient fuel combustion and clean air intake, preventing engine carbon deposition and power attenuation. Third, use qualified standard diesel oil to avoid engine jitter and power instability caused by inferior fuel. Fourth, inspect the cooling system and electrical control system periodically to ensure good heat dissipation and stable power generation, effectively reduce failure rate and realize long-term efficient and stable operation.
