Standby 40kW Silent Type Generator Set Exported to Bulgaria

Aug. 27, 2026

At Dingbo Power, we know that the best solutions start not with a product sheet, but with a deep understanding of the customer’s real needs. Our latest success story—a 50 kVA diesel generator set now ready for shipment to Varna, Bulgaria—is a perfect example of this philosophy in action.

Project Demand Confirmation

On May 30, Dingbo Power initiated in-depth communication with a new client from Bulgaria to clarify their exact power supply demands. The customer required a diesel generator set to serve as an emergency backup power source for their solar PV system. Different from regular prime power generators, this unit would only be used for occasional standby power support, with an annual operating time of less than 100 hours. During early negotiations, the client stated that they had no strict brand requirements for engines or alternators. Instead, they focused on reliable quality and cost-effective pricing suitable for low-frequency standby scenarios.


Professional Customized Generator Solution

Based on the customer’s practical application environment and budget positioning, Dingbo Power avoided rigid template quotation. With more than 20 years of professional experience in the generator industry, our technical team customized the most matching configuration for the project. We recommended a generator set equipped with a Shangchai engine and Dingbo self-produced alternator. This mature configuration features stable performance, strong adaptability for standby use, and outstanding cost advantages, fully meeting the low-hour working demands of solar power systems.


The final configuration was agreed upon as follows:

Engine: SDEC 4ZT3.2-G21

Alternator: Dingbo DB-40-4A

Controller: SmartGen HGM6110N
