Wiring Advice: 2 parallel 48V Inverter RS Smart Solar + Skylla Charger (Generator Voltage Question)

Hello Victron community. I have an off-grid solar battery system in an isolated community and am looking for help to safely connect a generator and prepare for possible grid connection.

My System Specifications:

  • Inverters: 2x Victron Inverter RS Smart Solar 48/6000 (Off-Grid, No AC Input)

  • Charger: Victron Skylla-TG 48/25 (230V Input)

  • Solar Array: 10 kW Total PV Capacity.

  • Battery Bank: 48V Bank (4 parallel strings).

    • Batteries: 32x Tensite 6V 600Ah GEL (8 in series per string).
  • Generator (Gas): Husqvarna G3200P (Gasoline, 3.2kW Peak / 2.7kW Rated, 110/220V output).

  • Generator (diesel): Lister 8/1-5 (Diesel, 5kW Peak 110V output)

  • Step-up transformer: 110V to 220V

  • Grid Status: Currently Off-grid (Grid connection expected in 6 months).

  • Goal: I need to connect the generator (and later the grid) to charge the 48V battery bank. Since the Inverter RS Smart Solar does not have an AC Input, I I have just purchased the Skylla charger to use the generator for battery charging. Also we plan to have grid power in 6 months. The grid power has three lines, 2 hot are 110V. I am looking for the best way to connect the generator and prepare for future Grid connection.

  • I would like advice to ensure safe connections. If anyone has a one-line diagram of this system please share. I have 2 generators but will use the Husqvarna for now. In the future want to use the lister as it is very fuel efficient, the output is 110V but i have a step-up transformer.

Thanks in advance for any suggestions.

This is a diagram from the Victron site. our DC bus bar has 4 parallel strings entering from the batteries and two lines exiting to the inverters. Can the Skylla charger connect directly to the AC and DC busses?

This is what I am planning to do. Should I have any extra fuzes or smartshunt? Should this work just fine?
