What Are ANA Parallel Generator Units Capable Of, And How Do I Set Them Up?
A simple overview of paralleling generators, wiring requirements, bus setup, and available operating modes.
Parallel generator units allow you to combine the output of multiple generators to achieve higher total kW capacity and more efficient load handling. With ANA’s parallel technology, fleets can create up to 12,800 kVA of power or run units individually when only lower output is required.
Paralleling is the process of having multiple generators produce voltage at the same time. For example, two SDG400P units each produce 320 kW on their own. When paralleled, they work together to produce 640 kW while maintaining ANA’s ±0.5% voltage regulation. Communication between units is handled through CANBUS.
Setting up units in parallel is straightforward. Each generator includes connection points on its remote terminal strip for CAN High (CH), CAN Low (CL), and CAN Shield (CSHLD). CAN High and CAN Low must be wired from unit to unit, and the shield should be grounded at only one end. The controllers also need to sense the same bus voltage. The simplest way to create a shared bus is with an ILINE box, which combines multiple lines into one output.
To run paralleled generators, connect the CAN wiring, start each unit in manual mode, and close the breakers. ANA offers two operation modes: Load Sharing and Power Management. Load Sharing gives the operator full control of which units start and when breakers close. Power Management automates these decisions through the ComAp controller. It can start additional units as needed, balance load automatically, and use Run Hour Equalization to prevent uneven runtime between generators.
