Parallel Generator Sets: A complete guide to their operation and our solutions

Discover everything you need to know about the parallel operation of generators and the solutions we offer.

How do Parallel Generator Sets work?

Operating generators in parallel involves synchronizing two or more units at the same frequency and voltage, allowing them to work together to power a common network.

This configuration enables the generation of a large amount of energy, exceeding the capabilities of a single unit with similar characteristics.

This method ensures that there is always at least one main generator active and connected to the network, which can be rotated periodically to evenly distribute usage hours and plan maintenance in a staggered manner.

When the generator is equipped with parallel operation capabilities and the onboard power demand exceeds a predefined threshold, another generator is automatically instructed to start and connect, balancing the load evenly across all active units.

If the demand decreases, the additional generators are automatically disconnected and stopped, allowing maintenance to be carried out without interrupting the electrical supply, as the system disregards inactive equipment.

Benefits of parallel operation in Marine Generators

Energy Efficiency: Adaptability to demand fluctuations with lower fuel consumption, activating or deactivating units as needed.
Continuity and Safety: Ability to perform maintenance without affecting the electrical supply, ensuring constant energy even during repairs on the main unit.
Enhanced Reliability: The simultaneous operation of multiple generators prevents failures and ensures an uninterrupted electrical supply.
Reduced maintenance: Reduced individual wear due to operating hours being distributed across multiple units.

Solé Solutions: Generators in Parallel

Why solé advance parallel generator sets are the best choice?

At Solé, we stand out by simplifying the implementation of these advanced systems through our Plug & Play approach. This includes a generator set prepared for parallel operation and an integrated electrical cabinet equipped with everything required for proper operation.

Our systems incorporate dedicated controllers that automate the synchronisation process, regulating frequency and voltage to ensure optimal performance, while simplifying installation and reducing costs and technical complexity.

Generators with electronic governor for parallel operation

When your project requires a parallel system, Solé offers marine generators equipped with complete control and power kits, designed to synchronise multiple generators with each other. These systems enable coordinated and efficient operation of several generators, ensuring a stable and reliable power supply on board.

We also provide specific equipment for shore power synchronisation, enabling safe and precise integration with port electrical infrastructure. This ensures a smooth transition and continuous operation during harbour manoeuvres.

Our parallel operation solutions are available for both Type Approval Certification (TAC) generator sets and non-TAC models, adapting to the needs of each project.

Control and power kit

For parallel marine generator sets

The IP65 Cabinet, together with the Solé Advance control panels, is designed to provide a complete control and protection solution for your generator sets. This system includes an electrical cabinet equipped with a power switch, responsible for connecting the generator to the onboard network safely and efficiently.

It also features an InteliGen 200 controller, which enables parallel operation management and facilitates both manual and automatic start/stop of the generator.

The controller offers multiple monitoring and control options to ensure accurate and efficient performance at all times.

The cabinet is fitted with all the necessary protection devices to guarantee user safety and equipment integrity, making it a reliable and robust solution to maintain optimal performance on board
