^^^^ Jon R, I’m starting to buy components - what would your recommendation be for positive (+) cable size from the house battery positive post (and fuse size) out to the positive bus bar and loads), given your reply above? Wondering if the #6 is too small?Even with the CPAP machine at 2 plus amps continuously all night plus the fridge and other loads, i think your usage in a 24 hour period won’t exceed 50 amp hours.
(As we discussed earlier for the dc to dc charger itself it will be the #6 wire and a 50A fuse, (thank you for that!) but I wasn’t sure on a fuse size for just the house battery even though it has built in 200A BMS)
I saw a post that said fuse size should be max amp load plus 25% but I know that my estimated 50A hours consumption in a 24 hour period won’t be all at the same time.
I didn’t mention, I’ll be using an ANL style fuse block to accommodate the cable and lug terminals.
Here’s a link to the battery I bought. I decided on it by pouring over manufacture specifications and buyers reviews and ratings. I wasn’t a member of the Wander the West forum yet or I would have asked. I know you had questions about it, and honestly I’m still trying to understand all the built in features. The internet reviews (top 10 LiFePo4) seem to change all the time, I really hated breaking the bank on some of the ones that were deemed best. I guess I’ll know in time in how it functions for my purposes.
