A refrigeration system for a refrigerated cargo container includes two or more refrigeration circuits, each circuit configured to cool a compartment of the refrigerated cargo container. Each circuit includes a compressor (38) to compress a gaseous flow of refrigerant, a gas cooler (40) in fluid communication with the compressor to cool the compressed flow of refrigerant, and an evaporator (46) located at the compartment and in fluid communication with the gas cooler and the compressor. An electrical generator (34) is operably connected to the compressor of each circuit to drive the compressors and a control system operably connected to the electrical generator and the two or more circuits. The control system is configured to calculate a maximum electrical power generated by the generator, calculate a target electrical load of the components of each circuit, and distribute the available electrical power from the generator to meet the target electrical load of each circuit.
