2x Charger 1

So correction I was wrong. A battery isolator does not allow two different charging profiles, it just allows the one way charge from the alternator to be shared between multiple devices. It does not manipulate the voltage it just shares it. If you need to regulate different charging profiles you need a DC to DC charging converter.

I know the Bluetti DC to DC charger regulates the voltage on the Bluetti end, but depending on where in the chain it is in respective to the alternator you may also need a dc to dc converter as well. Isolator to split the charge. DC to DC Converter to regulate the charging profiles for each battery chemistry. So you still need the isolator to allow charging to both, but you also need the converter so the charging profiles are also correct.

Sounds like the simplest option is to just run 1 charger 1 and accept the fate of 560W charging. You can top off in 12 hours with just 1 Bluetti Charger 1 assuming 90% charging efficiency. I would ask myself do you actually consume 6000W a day or is this just a larger reserve bank for running multiple days off grid. Your usage profile might actually dictate you can get away with just 1 for now. Food for thought :slight_smile:

Yeah, I think, for now, I will just run 1 C1 and the solar panel and see if I fall short of keeping the Pecron stuff topped off, then consider my options. I know that during the night in the summer with the portable A/C and fridge/freezer, a laptop, maybe a tv, I will probably be using a minimum of 300 watts so will easily use 3kWh over a 10 hour period. Solar alone should be able to replenish that over 10 hours of daylight even though the panel will be laying flat. If not, then I could go for a drive or even let it idle for a while. I will just have to wait and see how it goes.
Thanks for all your help and information. I have a much better idea of what is involved in trying use 2 C1s, and who knows, maybe in the near future someone will come out with a new, better solution.
I think I am still going to have to get an auxiliary battery, though. I am concerned my existing battery will not be able to run the C1, the new stereo amp, and all my other factory accessories at the same time.
Thoughts?
