Polyphase
A small description of the installation. My customer has a polyphase supply with one phase feeding a garage and another phase feeding the house. The DNO has allowed me to install an 8KW inverter per phase as long as they're linked and communicate. They want battery storage but ideally, the batteries would be linked to both inverters via a common bus bar so the battery storage can be shared between both inverters. If the common bus bar isn't an option then I would have to install 3 batteries on the house phase and one battery on the garage phase.
Is there any videos on you tube that show a polyphase set-up please. I'm also after a video that shows a setup which includes, if possible?
2no inverters that communicate with each other (both inverters need to be a master, one on each phase)
Sunsynk battery storage linked to both batteries via a common bus bar.
Appreciate any help
I do not believe that will work. when you parallel 2 inverters they will want to synchronise the outputs as single phase. While they may operate in parallel in this mode, they will complain about the DC Bus is unbalanced when the loads are different on each inverter. Split phase does need 2 inverters, and 2 batteries and they must not be paralled.
