Electrical setup question

Hey guys and gals, i am looking to uppgrade my electrical system and i´m wanting to use the Simarine system, trying to wrap my head around everything i need i have alot of the system already, but it´s the simarine and lifepo4 batterybank that is the biggest change am i missing something here ? :electric_plug: ELECTRICAL SYSTEM PARTS LIST

1) POWER GENERATION

  • 6 × 500 W high‑efficiency solar panels (24 V‑compatible)

2) BATTERY BANK

  • 2 × 24 V 314 Ah LiFePO₄ batteries (house)

  • Battery main disconnect switch (i have one)

  • Class‑T main battery fuses (e.g., 300 A or 400 A) + holders

3) CHARGING & INVERTER

  • Victron MultiPlus‑II 24/3000/70‑50 inverter/charger

  • Victron Orion‑XS 24→24 DC‑DC charger (alternator) (already installed)

  • Shore power inlet (230 V) (already installed)

  • AC distribution panel + AC circuit breakers

4) SOLAR CHARGE CONTROLLER

  • Victron SmartSolar MPPT charge controller (sized for ~3 kW) (already have one but i will need a bigger one if i get bigger panels)

5) DC DISTRIBUTION & PROTECTION

  • Victron Lynx Power In busbar (I have busbars already but i wanted the Lynx one´s for cleaner install this time around)

  • Victron Lynx Distributor (fused DC outputs)

  • DC breakers / fuses for:

    • Solar feed

    • DC‑DC charger

    • Inverter DC input

    • Orion DC‑DC output

    • 24 V fuse panel feed

    • 12 V/DC‑DC feed

  • 24 V fuse box (already installed)

  • 12 V fuse box (already installed)

  • Assorted blade fuses + fuse holders

6) SIMARINE MONITORING

Core

  • Simarine VIA main display/controller

  • Simarine SPDU52 power distribution hub

Shunts (monitor charging sources)

  • SC303 × 3 (one each for):

    • Solar → battery

    • DC‑DC alternator → battery

    • MultiPlus charger/inverter DC output

DC Load Monitor Modules

  • SCQ25 × 2 (for grouped branch loads)

Sensors

  • Tank level sensors:

    • Fresh water tank

    • Grey water tank

    • Black water tank

    • Diesel tank (optional)

  • Temperature sensors:

    • Outside

    • Living area

    • Cab area

    • Boot/trunk area

    • Grey tank

    • Black tank

  • Simarine inclinometer sensor

7) DC LOAD & CONVERTERS

  • Victron Orion 24→12 V DC‑DC converter (for 12 V loads) (already installed)

  • 12 V load fuse box and branch circuits (installed)

  • 24 V load fuse box and branch circuits (installed)

8) CABLING & CONNECTORS

Already have a system in place that has been working for many years but some cables will need to be checked and replaced, i think for example i used oversize solar wires that will work but ill have to check ofcourse, already have a 3000w 24v inverter so i may be able to use the same wires on the victron etc but i will go over everything.

I know it´s a massive list but i´m just trying to make sure i get everything i want for what i need it for. The simareine system is going to help me automate somethings with the alarm/relay functions like heating pads on grey/black water tanks, and it´s really just vanity i like seeing the data in and out i´m abit of a nerd :slight_smile: here´s my home, this is from Denmark 2 years ago
