If you pause the video on the screen that shows all the individual components and wiring diagram, the yellow boxes represent the fuses. When I get around to upgrading the batteries, the battery fuse and inverter fuse will be larger.
Great video! It just occurred to us - We recently upgraded to lithium batteries - 1st 2 were 100Ah, set in parallel and we used 2 AWG to connect each together - but we've sent them back and are awaiting the arrival of our 2 230Ah batteries. I'm thinking, our 2 AWG cable is not large enough - from what I can tell, we need 4/0 cable to connect them - Would you agree this correct? Also, it occurred to me that maybe our shunt/battery monitor will now not handle this large battery bank - we plan on following your parts list 100% when it's time to install our inverter. :) Our shunt is the stock Furrion that came with our 2023 GD 337RLS - if we need the larger shunt, we'll get the Renogy 500 AMP Battery Monitor with Shunt. Thanks for you help. This may not be the last you hear from me lol. I may even reach out on the GD forum if that's okay. (I did just reach out to Lippert and their highest shunt handles 350, so that answers 1 question - off to order)
When I installed the LiTime 230ah batteries in parallel, I did upgrade the cables from the batteries to the bus bars to 4/0 welding cable. From the bus bars to the inverter is still 3/0. I installed a 250a terminal fuse on each battery and upgraded the fuse to the inverter to a slow blow 300a fuse. I don’t know about the Furrion shunt, but they are all pretty generic and can handle up to 500ah battery banks. You can check by adjusting the setting on the panel.
I actually added a second converter that was lithium compatible. The original converter stays off at the circuit breaker - just for backup in case the new one dies.
