There are an increasing number of bi-directional benchtop power supplies commercially available for general applications such as battery testing and energizing magnets etc. All the manufacturers seem vague or do not mention regulations around grid connection. Are there any harmonized standards for these small scale installations where energy recovery is sporadic and not continuous at at fairly low levels eg Typically less that 1.5KW but definitely <10KW. In my application I would like to be able to ship to all the major areas of the world but navigating hundreds of separate regulations could be prohibitive.
