That's really helpful thanks Jonny, didn't think I would be able to get away with going so low in terms of capacity. Just had a google and may just go for something like this:Jonny Hart wrote: ↑Sun Jun 18, 2023 7:14 am Hi Rich, if you go for one of our 175A alternators you can go smaller on battery capacity. I run an Odyssey AGM (PC925) in my SC and a Deadweight (prototype) in my 993.
With the battery isolator, we have on occasion had issues where the isolator cannot sustain the current for the AC. TBH, this has generally been with cheap eBay isolators. Bosch ones tend to be ok and I would think the old school one is probably better than the new plastic key type.
