Hybrid 3 Phase inverter with Multiplus II GX

DIY

Hi guys, I’m thinking on buying 3 Multiplus II GX inverters to make an hybrid 3 phase inverter.
I just have some questions:

  • Is this possible?
  • What do I need to buy to make it work with 3 phases?
  • If my battery is low, will it switch to the normal grid?
  • If it switches, will the whole house be without energy for 1 second or more?

By the way, my normal grid is 3 phase and has 9kw max.

Thanks for the help.

You dont need 3 multiplus gx, just one gx and 2 normal

Start by reading various manuals from victron
And ask a local official dealer on design

You can also follow free courses on victron professional

To answer your questions:
Yes this is possible

It will use grid/solar with low battery

If loads are on ac out 1, and grid fails it will switch in about 20ms so you hardly notice

Normal usage between grid and battery is smooth you wont notice

Remember its a battery based system, so cant be used without or too small battery
