February 17, 20224 yr An interesting problem I have come up against. I have a client that is looking at replacing their current UPSs (with VRLA batteries) at a number of their sites with Inverter/Lithium battery systems. We have a solutions for majority of the sites, however there are 2 sites the UPSs that have a 3-phase input going to a single-phase output. Would one be able to parallel inverters (e.g. Victron, Axpert, etc.) so that they except a 3-phase input but output to single-phase? This would be preferable for the client as opposed to rewiring the DB to accomodate. Thanks in advance

Not possible with Axperts. According to the 4kVA/5kVA Parallel Installation Guide, all AC inputs MUST be on the same phase for parallel operation in single-phase.
