3x 8 kW installtion for 3 phase application
Howdy everyone, I am currently busy with a project that includes the use of 3x Sunsynk 8 kW inverters to supplement a laboratory. I have the following questions, so please don't mind my ignorance, if it arises.
Will it be possible for the system to supplement the grid, where each inverter is connected to each of the 3 phases in the main DB, alongside the grid? So each inverter will receive its grid power, however, it will the be able to also feed into that same connection, with PV, as well as battery backup, as it exists in the current DB. I can attach an image for clarification. The main reason for doing this, is due to the inverter capacity being more than the load of the lab, thus deamin it unnecassry to split the essential from the non-essential, if that makes sense?
Note: The CT's will be installed to prevent the push back of power beyond any point before the main DB.
Note: The neutral of each inverter will be connected to the common neutral in the main DB to avoid any 400 V madness.
Thanks in advance!


This is the method that is used when using 3 * single phase inverters. Keith from Sunsynk has produced many intersting videos on this topic. Check out this link - https://www.sunsynk.org/post/copy-of-paralleling-inverters
Is there a reason why you would not consider a single 3 phase inverter?
