Synchronised Industrial Generators (350kVA+)

What is a synchronised generator system? Bundu Power supplies and maintains industrial paralleling plants where 2 to 32 diesel generators run together on a shared bus, typically from 350 kVA per unit upward. Every system we synchronise uses DeepSea DSE8610, DSE8620 or DSE8660 MKII controllers depending on whether the site needs gen-to-gen load sharing, single-set mains synchronisation, or utility transfer control.

Bundu Power has more than 20 years of experience supplying and maintaining diesel generators across South Africa. We supply and maintain synchronised generator systems regularly — from two-set redundancy plants to large multi-megawatt sites — and operate synchronised sets in our own rental fleet, so our equipment and service model is proven in the field.

We specify DeepSea load-sharing controllers exclusively for synchronising work: the DSE8610 MKII for multi-generator paralleling, the DSE8620 MKII where a single set must synchronise with mains (and can later be reconfigured for multi-set duty), and the DSE8660 MKII to manage transfer between the generator bus and the utility supply.

Why Synchronise Generators?

Better Fuel Efficiency

Load is shared across running sets so each engine operates closer to its optimal load band instead of one oversized unit running lightly loaded.

Modular Capacity

Add or remove generators as site demand grows or contracts — without replacing the entire plant in one step.

Built-In Redundancy

If one set is offline for scheduled service or a fault, remaining units carry the load while repairs are completed.

Smaller Units, Same Total kVA

Multiple smaller generators can fit sites with space or access constraints better than one very large single set.

Automatic Load Demand

DeepSea controllers start and stop sets on load change, balance running hours across the fleet, and optimise how many generators stay online for the current demand.

DeepSea Synchronising Controllers

Bundu Power selects the DeepSea DSE86xx MKII module for each role in the paralleling architecture. Each controller type below has a dedicated product page with full specifications.

Controller Primary Role Key Capability
DSE8610 MKII Multi-generator load sharing Synchronises up to 32 generators on a common bus (gen-to-gen paralleling)
DSE8620 MKII Single-set AMF synchronising Synchronises one generator with mains; software-configurable as DSE8610 for multi-set upgrades
DSE8660 MKII Mains / ATS control Manages transfer and synchronisation between the generator bus and utility supply

System Components

  • DeepSea DSE8610 / DSE8620 / DSE8660 MKII synchronising controllers (one type per role in the plant)
  • Electronically governed diesel engines with integrated governor and AVR control
  • Motorised circuit breakers rated for full-load closing onto the bus
  • Central busbars and synchronising protection
  • ATS or mains interface via DSE8660 MKII where grid connection is required
  • Optional remote monitoring via DeepSea DSE890 MKII and DSEWebNet

Typical Applications

Mining & Heavy Industrial

High-capacity paralleling for 400V and 525V industrial generators where modular megawatt-scale backup is required.

Hospitals & Healthcare

N+1 redundancy so critical circuits remain supplied while any single set is serviced.

Data Centres & Telecom

Scalable plants from 2 to 32 sets with load-demand control and mains parallel options.

Industrial Parks & Rental Fleets

Flexible capacity for tenants or hire fleets — Bundu Power uses synchronised sets in our own rental operation.

When Paralleling Makes Sense — and When It Does Not

Best suited when

  • Individual generator size is 350 kVA or larger
  • Site load is variable and modular capacity is valuable
  • Redundancy during servicing is a operational requirement
  • Multiple smaller sets are easier to site than one very large unit

Limitations to plan for

  • Higher upfront cost than a single standalone set (controllers, switchgear, specialist sync equipment)
  • Load must be balanced across running units — poor load sharing increases wear
  • Protection and load-sharing configuration require experienced paralleling engineers on site
  • Not cost-effective below roughly 350 kVA per unit for most applications

Synchronised Generators: Frequently Asked Questions

A synchronised generator system connects two or more diesel generators in parallel so they share a common electrical bus and supply load together. Each genset is matched for voltage, frequency and phase before closing onto the bus. Load is distributed across running units, improving fuel efficiency and giving built-in redundancy if one set is offline for service.

Bundu Power typically supplies synchronised systems from 350 kVA per unit upward. Below that threshold the cost of synchronising controllers, motorised breakers, busbars and specialist sync switchgear usually outweighs the fuel and redundancy benefits. For sites needing modular capacity above 350 kVA, paralleling becomes the practical choice.

Using DeepSea DSE8610 MKII load-sharing controllers, up to 32 generators can operate in a single synchronised plant. Bundu Power regularly supplies systems from 2 to 32 units on one site, scaling capacity up or down as load changes.

The DSE8610 MKII is the multi-generator load-share controller for gen-to-gen paralleling (up to 32 sets). The DSE8620 MKII synchronises a single generator with the mains supply and can be software-configured as a DSE8610 when the site upgrades to multiple sets. The DSE8660 MKII is the mains and ATS controller that manages transfer and synchronisation between the generator bus and the utility supply.

Yes. A DeepSea synchronised plant can run in parallel with the mains (utility) supply for peak shaving, base-load transfer or short-term parallel operation. This requires a DSE8660 MKII mains controller alongside DSE8610 or DSE8620 generator modules, plus correctly rated switchgear and protection.

Bundu Power supplies and maintains synchronised generator systems across South Africa. With more than 20 years of generator experience and synchronised sets in our own rental fleet, we specify DeepSea DSE8610, DSE8620 and DSE8660 controllers for industrial paralleling from 350 kVA upward.

A synchronised plant requires electronically governed engines, motorised circuit breakers, a central busbar arrangement, synchronising protection and an ATS or mains interface where grid connection is involved. Each generator must be sized and configured for load sharing. Connection, protection and on-site testing must be completed by your qualified electrical contractor before the plant goes live.
