Genset Control & Distribution Manufacturer Enerzip supplies generator control and power distribution systems for diesel generator sets, gas generator sets and multi-unit power projects. The product range mainly includes ATSE Series Automatic Transfer Switches and EZ-PGC Series Paralleling & Grid-Connect Systems.

These systems are used to control, switch, synchronize, distribute and monitor generator power in commercial buildings, hospitals, data centers, factories, mines, oil and gas sites, telecom facilities, public infrastructure, remote power stations and industrial power plants. The final design depends on the on-site electrical single-line diagram, generator quantity, rated current, operating mode, load type, protection requirements and communication interface.

ATSE Automatic Transfer Switch System

Enerzip ATSE Series is designed for automatic switching between utility power and generator power. When the utility power fails, becomes unstable or falls outside the allowed voltage range, the ATSE system can transfer the selected load to generator power according to the confirmed control logic. When utility power returns to normal, the system can transfer the load back after the required delay.

The ATSE current range covers 80A to 3200A. Depending on the project requirement, the system can be configured with automatic transfer, manual operation, switching delay, return delay, generator start signal, mechanical interlock, electrical interlock, power source position indication, alarm output and status feedback. The cabinet design should match the rated current, short-circuit level, cable entry direction, installation space and load priority of the project.

Paralleling and Grid-Connect System

Enerzip EZ-PGC Series is used when multiple generator sets need to operate together. The system supports generator synchronization, kW and kVAr load sharing, generator start-stop sequencing, circuit breaker control, fault isolation, common busbar protection and grid-parallel operation where local regulations permit.

For larger generator power systems, the paralleling system can be configured to support up to 99 generator sets according to the confirmed project scope. This type of system is commonly used in power stations, data centers, mining sites, industrial parks, oilfield projects, remote power systems, microgrids and projects requiring staged capacity expansion.

In a multi-generator system, the paralleling cabinet controls how generator sets start, synchronize, connect to the busbar, share the load and disconnect when necessary. If one generator is stopped for maintenance or trips due to a fault, the remaining units can continue operating according to the designed control logic, provided the available capacity is sufficient for the load.

Control Logic and Communication

Enerzip can configure the control system with commonly used generator controller platforms such as DSE, ComAp, DEIF, SmartGen or other suitable options according to project requirements. Communication interfaces can include dry contacts, RS485, Modbus RTU, Modbus TCP/IP, CANbus, PLC, SCADA and BMS interfaces.

Typical monitoring signals include ATS position, circuit breaker status, generator running status, generator alarm, trip signal, common bus status, number of online generators, operating mode, load status and system fault information. For hospitals, data centers, telecom sites and industrial control rooms, these signals can be integrated into the customer’s monitoring system according to the agreed interface.

Applications

In commercial buildings and high-rise facilities, ATSE cabinets are used to switch emergency lighting, elevators, fire pumps, smoke exhaust systems, access control systems, security systems and building management loads between utility and generator power.

In data centers and telecom facilities, generator control and distribution systems are used together with UPS systems, generator controllers and monitoring systems. The ATSE cabinet manages the transfer from utility power to generator power, while the paralleling cabinet manages multiple generator sets on the generator side.

In hospitals and medical facilities, generator transfer and control systems support critical loads such as operating rooms, ICU equipment, medical gas systems, surgical lighting, laboratories, diagnostic equipment, emergency lighting and critical HVAC systems. Clear power source indication, interlocking and maintenance isolation are important for these applications.

In factories, process plants, mining sites, oil and gas facilities and remote power stations, parallel control cabinets are used to manage generator synchronization, load sharing, automatic start-stop sequencing and fault isolation. These projects often require consideration of motor loads, long operating hours, dust, heat, vibration, remote monitoring and future capacity expansion.

Project Information Required for Quotation

To prepare a suitable genset control and distribution solution, please provide the following information:

• Required system type: ATS, paralleling, grid-connect, or ATS plus paralleling
• Generator quantity and rated power of each generator set
• Voltage, frequency, phase and rated current
• Generator controller brand and model, if already selected
• Single-line diagram, if available
• Circuit breaker rating and cable entry requirement
• Main loads, motor loads, UPS loads, medical loads or critical loads
• Operating mode: standby, island operation, peak shaving, grid-parallel or microgrid
• Required communication interface: dry contacts, RS485, Modbus, CANbus, SCADA or BMS
