5. FAQ (Frequently Asked Questions)
Q1: What is the practical difference between prime power and standby power of the SDEC 4ZT3.2-G12 generator set?
The 33.6kW/42kVA prime power is the rated continuous power of the unit, which supports long-term uninterrupted full-load operation and is mainly used for daily off-grid main power supply and long-duration continuous power generation. The 37kW/46kVA standby power is emergency peak power with a 10% overload margin, specially designed for short-term emergency power supply during municipal power outages, and long-term full-load standby power operation is not allowed. In actual use, users need to distinguish scenarios strictly: take prime power as the standard for continuous power generation, and standby power only for emergency instantaneous power supply, so as to avoid equipment overload damage and extend the service life of the generator set.

Q3: How to maintain the 4ZT3.2-G12 generator set to ensure stable performance and standard fuel consumption?
The standard full-load fuel consumption of the unit is 7.71L/H, 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 loss. Second, replace diesel filter, oil filter and air filter regularly to ensure sufficient fuel combustion and clean air intake. Third, use qualified standard diesel fuel to prevent carbon deposition, engine jitter and power instability caused by inferior fuel. Fourth, inspect the cooling system and circuit system periodically to ensure good heat dissipation and stable power generation, effectively reduce failure rate and maintain long-term efficient and energy-saving operation of the equipment.
