Battery compatibility with 3 phases ESS System ?

Hello,

After many 1 phase systems installed with Multi, Quattro, MPPT, Fronius, ESS , Lithum LG Resu (3.3; 6.5 & 10kWh) and running all fine (check YonneSolaire on VRM), I want to install a 3 phase systems with GX, ESS, 3 MultiGrid 3000, 9kWp Solar with Fronius Symo 8K on 3 AC OUT and a 10kWh lithium battery on a single DC line.

I just read on your Battery compatibility list that it is not possible to use LG Resu with 3 phase system, right ? What is the reason ?

Checking some other battery (BYD & Pylontech I can buy) in your list I see that the 3 phase is clearly presented on a table with some battery and nothing is told about 3 phase for some others batteries... So my question is : Do you have a list of battery I can use for ESS 3 phase system ? Or can you recommend BYD & PYLONTECH ?

Thanks a lot

Hi @Rodolphe - YonneSolaire

Both BYD and Pylontech are suitable for 3 phase systems. Others may also be suitable, even though not specifically mentioned (e.g. BMZ and MG).

LG and Victron engineering teams have not certified the LG product for 3 phase applications. It may work, but is not tested or approved, and is not supported.
