5 hp Single Phase DC Reactor, 8A

Q1: How to select the right DC reactor for inverter?

First, select an appropriate rated current based on the inverter's DC bus current, leaving a certain margin to avoid overload. Second, match the DC voltage level to ensure insulation safety. Simultaneously, select an appropriate inductance (typically 2%~5% impedance) based on application requirements, achieving a balance between harmonic suppression and system response. For photovoltaic, energy storage, or industrial frequency conversion applications, the operating environment and grid quality must also be considered.

Q2: What parameters should be considered when selecting a DC line reactor?

When selecting a DC smoothing reactor, focus on parameters such as rated current, inductance, rated voltage/insulation class, reactance rate, temperature rise, and heat dissipation method. These factors directly affect the DC link choke's filtering effect, harmonic suppression capability, and long-term stability. Furthermore, core material, loss level, and installation dimensions are also important, affecting equipment efficiency, noise, and practical installation feasibility.
