Two MultiPlus in parallel

Hello,

If I have two Multiplus Compact 800VA on the separate batteries (two separate systems; solar system and wind system), can I put their AC output in parallel (they aren’t configured parallel) and make micro island grid? Can I control them by external 3-way switch (one on, one off, or both on) and do they always divide load fifty-fifty?

Thanks for your support!

No, you cannot connect MultiPlus' in parallel unless they are configured to work in parallel via communication cable. Their outputs will be out of phase and there will be a problem.

When you configure two MultiPlus' in parallel, they must come off the same battery bank, with identical cabling - more information here - https://www.victronenergy.com/live/ve.bus:manual_parallel_and_three_phase_systems
