Unequal phase loading can occur when a property combines three-phase machinery with independently operated 230V circuits. For example, lighting and office equipment may be concentrated on one phase while other phases supply smaller loads. The ASP 8–12kW three phase solar inverter has published rated phase outputs of 2.6kW, 3.3kW and 4kW for the respective models. These values provide an important reference when planning how single-phase circuits are distributed. Unlike the total three-phase output rating, the per-phase rating helps identify whether a particular phase may become overloaded. The available product specifications do not establish a separate 130% or 150% phase-imbalance allowance for this series. Installers should therefore follow the model's published phase limits and relevant manual requirements rather than assuming the overload characteristics of another ASP product apply.
