Renogy 3500w Inverter Installation on 2015 Cedar Creek Silverback

[Minky]

I am planning to install the Renogy 3500-watt solar inverter utilizing my existing RV hardware wherever feasible. I have outlined the following plan for the installation. I respectfully request that solar energy experts review it and provide feedback, along with detailed explanations where necessary. Thank you.

Wiring Schematic Description
Below is a textual description of the wiring schematic:

1. Shore Power to Surge Protector:
   • Shore power inlet (50A) → EMS-HW50C surge protector (6 AWG, L1, L2, N, G).
2. Surge Protector to Distribution Panel:
   • Surge protector output → AC input of distribution panel (6 AWG).
3. Distribution Panel to Inverter:
   • AC output from panel (dedicated 30A breaker) → Inverter AC input (10 AWG).
   • Inverter AC output → Sub-panel or panel AC bus (10 AWG, 50A breaker).
4. Battery to Inverter:
   • 48V 100Ah LiFePO4 battery → 100A disconnect switch → 100A Class T fuse → Inverter DC input (2/0 AWG).
5. DC-DC Converter:
   • Battery → 40A fuse → 48V to 12V DC-DC converter (10 AWG).
   • Converter output → DC fuse panel (8 AWG).
6. Solar Panels:
   • 4 × 400W panels (2S2P) → Combiner box → 30A breaker → Inverter PV input (8 AWG).
7. Grounding:
   • Battery negative, inverter, DC-DC converter, distribution panel, and surge protector grounded to RV chassis (8 AWG).
8. Monitoring:
   • Battery monitor shunt on battery negative, connected to display.

I am by no means a solar expert, but I am very surprised that you have not heard from anyone on the forums. I happen to know someone that is in my opinion, a truly expert on solar system design, construction, and advice. Let me suggest that you contact Chad Heiser to get his opinion.

I'm no solar expert either but the equipment and connections you describe look adequate to me. Whether they will meet your performance & capacity objectives is more than I can assess, though. For starters, you didn't say what this set-up is intended to achieve.

I just looking for evening use at campsites with generators curfew. TV, Starlink etc. no air conditioners. Possibly built up for future use.

You want to run a 3500 watt inverter with only 100AH and 1600 watts of solar?!?? Am I reading this right?

You missed the part about this being a 48 system with a 48 volt, 100 a/h battery. 4800 watt-hours or the equivalent of (4) 12 volt, 100 a/h batteries.

correct, will eventually add a 2nd 48v 100 a/h battery when prices come down.
