When using the HP-AHP20SA series in complex setups like 3-phase or parallel configurations with generators, it's important to ensure proper load balancing and power distribution across all phases. The system allows for flexible parallel unit arrangement in each phase, which should be configured based on power requirements and generator capacity. This approach helps in achieving stable and efficient operation in these more sophisticated system designs.

In addition, in such a hybrid system, the configuration of each device needs to be reasonable, and the diameters and lengths of all input and output connecting lines need to be equal.
