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

Ok got it now! You’re awesome thanks and have a great day.

Ok so I’m not certain about correct fuses and wires. I’m building the 24v DIY system with 2-12v 200ah life PO in series I have the 400w panel Renogy system 4x100w which I plan to series and parallel with 40a Rover MPPT. I will be going with the 24v 2000w inverter and the DC 24v to DC 12V 40A...

Hello to all. I'm new to battery builds but am quite thrilled about all I am learning to assist me along the way with my 1995 International 3800 conversion. Thanks to following Will Prowse I'm planning an initial 24v LiFeP04 build. I'm looking forward to all I will learn here and hope I have...

Got it thanks so much. I really appreciate you.

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.

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

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

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...

Also it’s 12v

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...

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...

These are the components I have. Plus another ANL 400amp which I think is maybe too big.

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...

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...

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.

This is my schematic so far for my dual input scc
