I am planning to install a 3 Phase ESs System with 3 Victron Quattros (one per phase), 2 MPPTs and Pylontech batteries (US3000C). Basically it is this system: https://www.victronenergy.de/upload/documents/3-Phase-Quattro-system-with-Cerbo-GX-Touch-50-BYD-LVL-Smart-solar-MPPT's.pdf
but with pylontech instead of BYD and with no generator as a first step, so just the grid input.
After researching and doing the online courses of Victron, everything is fine so far, but there are two major questions remaining:
- After mounting everything, shall be the first step to setup and start the mppts or shall be the first step to install and setup the 3 Quattros
- When you open the model, it can be seen that the Central Negative Busbar is grounded. As it is in a house installation, I can use the ground of the house here? So basically this would be the ground also comming with the Grid Phases (L1, L2, L3, N and PE) ?
Thanks for any help
