Has anyone got experience using one of these variable speed pump drives on a Multi 5k inverter?
It looks quite compact so I am concerned that it may not have sufficient (or any) filtering on the input. If it uses a simple rectifier to provide an internal DC supply it will conduct over a very small angle near the top of the input sine waveform and I am worried the Multi will not be able to handle the heavy current pulses involved.
The proposed pump has a 1200W 3-phase motor so would not in itself be a problem.
