    This is my schematic so far for my dual input scc

    Also it’s 12v

    My DC-DC is 50amp max for solar and alternator charging. Mppt limits 50% from each source for dual charging.

    My house battery is 200ah LiFePo4 it’s an Ampere Time which apparently has a restrictive 100ah BMS

    If you don’t have time to get back to me until after Christmas I completely understand. I just wanted to respond with where I am. All my negatives including the eg for the inverter go to the neg bus bar with the 350a shunt from my house neg and then the neg on the dcc50s <-> goes to the bus bar...

    Ah! Santa is good to me! I think I understand the code. I will diagram it and send you a copy. Thank you so much.

    Uh oh! Already purchased and begun installation. I have 2 195cca starter batteries in parallel. Haven’t been able to determine actual alternator amps yet. I also agree I should not ground to chassis. I’ve also re-wired my 4-100amp 12v panels in parallel and fused each with 20a fuses. I noticed...

    Hello again! I wonder if you would have any modifications you would suggest to the code you gave me (above) since I’ve taken your advice and purchased a dc-dc charger. It’s the Renogy DCC50S 12V 50A DC-DC On-Board Battery Charger with MPPT. I’m planning on just swapping it out with my current...

    Thanks! I’m upgrading the circuit breaker to the one you recommended previously. I do have a bus bar off negative battery terminal. I will add a bus to the positive side. “|->100_amp_fuse->dc_fuse_block->001_amp_fuse->shunt.pos” i.e. 100a fuse from positive bus to dc fuse block to 001a fuse...

    I re-read these posts and realized you thought I had a dc-2dc charger. Here's what I have: 400w 12v (4x100)PV, Renogy Rover 40a SCC with provided tray cables (8awg), a 12v 200ah Lifepo battery, 9" 4/0 cables from battery to 300a ANL fuse to 2200w Giandel Inverter with the provided 5awg cables...

    Wanted to get back to you and say thanks for all the helpful information and guidance. I really appreciate you!

    Thanks for your reply. I understand that alternator charging isn’t great on LiFePo4 batteries or I would have gone that route. But I will certainly look at the inverter/charger for future upgrade.
