Well its done. Now to figure out how to work a few of these items. I scrapped the Renogy charger and got a Orion XS on order and already installed a Smartsolar 100/50, a smartshunt and a Lynx Distributor. Four 250W Richsolar panels on the roof. Here in Salt Lake I did get 4.8kWh of...

Another update if anyone is still following along. The Lynx Class T power in wont be availabe in the US until June. Timing wont work for me so I ordered a Lynx Distributor. I will run individual 4/0 Wire from each battery to a 600A rated blue sea battery disconnect then through a blue sea...

So I got a chance to check everything out in the RV right now. Currently my 4x 6V 230Ah batteries are 2S2P and have a 600A fuse on positive and negative 3/0 wiring that is about 10ft in total lenght 5ft each. It seems the factory fused the 3/0 for 600A? I am going to get a Lynx Class T and...

Haha. I wasnt trying to put crap in it. I have never even seen the lynx stuff. Checking them out I should get the Lynx Type C Powerin and a Lynx Distributor. Should I use a 300A class T fuse on each battery in lead to the Lynx? I will finally get to head over to the RV tomorrow to check...

I dont think I will need to be pulling 600A from the batteries. I just know they are capable of producing that due to the BMS specs. I think the largest single item draw is my Magnum invertor which the specs say can pull 400ADC. I know the 12V system in the RV can pull some at the same time...

https://www.windynation.com/products/4-0-gauge-black-red-welding-cable-various-lengths-available Shows in the pic that its rated up to 105C. I dont mind going conservative and putting in larger wire when it comes to safety.

I am in no rush. I know I cant just drop in my batteries. I need to at minimum disable my automerge and add the DC to DC charger. If I dont the batteries have the ability to pull 100% of its capacity for hours on end. Adding the bus bars and fusing to them will be helpful if I add anything...

The wire I was planning on using is from Amazon seller recommeded by Will in his solar builds. Windynation. Shows its 105 rated. 2/0 Gauge 2/0 AWG 5 Feet Red + 5 Feet Black Welding Battery Pure Copper Flexible Cable + 10pcs of 3/8" Tinned Copper Cable Lug Terminal Connectors + 3 Feet Black...

Thanks for the link. That calculator is giving me the same results as the other but I like the interface. So for the 125A DC to DC charger I put in my info as follows 12v, 125A, 10 ft round trip length. For CCA I put max draw allowed by bms of 600A and selected branch since its not the main...

I should have put it in my original post now that I think about it. It a 2021. I have spoke to the spyder folks on how to disable the auto merge. Also since many of the systems are already installed I assumed it would be an easier project to tackle. My main concerns are just getting the new...

Alternator is a 160A unit on a ISB 6.7 Cummins. So the Renogy 50A should be safe for the alternator. The Magnum invertor is already installed so I was just using the bus bar to simplify the install of the new batteries. My thought process was on bus bar pair for all the 12v connections to the...

Currently the Smaller Jaboni controller and solar system and the magnum inverter are all installed from the factor. My RV is a Tiffin Allegro Red 33AA. Its a 35' diesel pusher that has a 8000W generator. I already purchased the Renogy IP67 DC to DC MPPT and the two Epoch 300Ah batteries. I...

I was using this one https://www.omnicalculator.com/physics/12v-wire-size There are a few others and they had the same results. https://www.wirebarn.com/Wire-Calculator-_ep_41.html I didnt actually crunch the calculations since I was getting similar results a few places.

Some good thoughts HarryN. The Epoch batteries have a recommended charge rate 80A each. So maybe I should shelve the additional 125A charger and see how the setup goes with the added solar and new batteries. I was going to do the charger first and additional solar second but I think I will...

Thank you for the reply. I used a calculator for the wire sizes. Did I not use it correctly? For the 125A charger for example if the 1 way run is less than 5ft it calls for 4 awg wire. Should I be basing it off the fuse size? Just edited to add I realized I wrote 8 awg wire for the...
