Hello All,
New to the Victron community.
I have a Victron quattro 48V/10KVA set up on a single phase currently off grid with 14KVA Generator which has been running for just over 2 years.
I’m looking to connect a grid connection soon & remove the generator due to the load demands on my home.
The Set up:
1 x Victron Quattro 48V/10KVA/140-2x100 - VW. Bus connection (Firmware - 2653481)
2 x Victron 450/100 Solar charger configured to 33 x 320 W Solar panels (Direct DC Coupled to Charge battery)
2 x BYD 14.7 KW/Hr Batteries with Battery monitor built in each battery
1 x Cerbo GX (V3.52)
1 x Hyundai single phase 14KVA 11KW real power Generator
Q: To fully utilize my system I’m looking to back feed to the grid - What’s the best solution once my generator is disconnected & have a single phase connection to the Victron Quattro L1 Input. ? (Do i need to install a ESS Relay ?)
Q: The Victron looks like it can utilize 2 phase input - Could i configure 2 x 230VAC inputs into the Victron as I’ve been offered 3 Phase connection from the grid & looking to install a car Charge ? (Any gain from 3 phase vs single phase from Grid as its only a few hundred pounds extra)
Q: Could i use the L2 output for a 7KW car charger to not overload L1 which has seen high loads at times as i have a GHSP / Over & Hob fed from the main distribution ?
Please note old photos 2 BYD batteries are now installed.
Any help is appreciated
Thanks
