Sanity Check: Victron 48V + Eco-Worthy Peak Shaving for Homelab

I’m in the process of building a UPS and peak-shaving system for my homelab (servers/networking gear). The goal is to charge up the batteries at night when rates are cheap and run the server rack off batteries during peak hours.

I’ve put together a wiring diagram and wanted to run it by you guys before I start wiring everything up. I want to make sure I haven’t missed anything obvious regarding safety or best

practices.

The Gear:

Inverter: Victron MultiPlus 48/3000/35 (120V)

Batteries: 2x Eco-Worthy 48V 100Ah (LiFePO4)

Distribution: Victron Lynx Distributor

Monitoring: Ekrano GX + SmartShunt 500A (decided to use the shunt rather than fight with Eco-Worthy BMS comms)

The Plan: I originally bought a Lynx Power In as well, but realized it was redundant since I can fit everything on the Distributor, so I’m planning to return it.

My specific questions:

1. Wiring: Does the diagonal wiring for the parallel batteries look correct to ensure equal draw?

Ekrano Power: I realized the Ekrano needs dedicated power (it won’t run reliably just off the VE.Bus cable if the inverter shuts down). I have it fused at 1A going to the Lynx busbars. Is this the standard way to do it?

3. Fusing: I’m planning on 125A MEGA fuses for each battery and the inverter. Does that sound right for this size system?

Any feedback or “gotchas” would be appreciated before I flip the switch!

Thanks in advance.
