Im not talking about solar panel voltage. In a 24 volt bank system, but you have some 12v loads, like in a toyhauler, can you parallel 2-24/12 40amp converters if your combined load is greater than 40amps? Does it see it as 2 40amp sources equalling 80?
Thank you. I was looking at at victron 24/12 100. It would be more than enough. Just sucks that it's $265.Yes, the two 40 amp converters will result in ~80 amps. However, don't be surprised if cheap converters don't measure up.
I've also read that if you do parallel 2x converters, and one has a slightly higher voltage, it will take most of the work all the time and could wear it out prematurely.
Curious why you need 80a? On my truck camper, to run the jacks for loading and off loading, I am running the original converter off the inverter to power just the jack controller and jacks. I switch it off when not needed.In a 24 volt solar system, If you need more than 40amps in your 12v system (toy hauler), can you parallel 2 converters to get up to 80 amps?View attachment 50502
I know this isn't towards me, but the circuit breaker going to my hydraulic pump is 80a, and I've read on forums that people have measured it to up to 70a in reality. Granted my pump runs the 6 leveling jacks and 3 slides.Curious why you need 80a?

Now I'm gonna have to check when I get home, you have me intrigued!I checked my jacks with my DSO scope and clamp on ammeter. Initial surge was 42a for 2 ms and 24a with all four running. I have a 720w buck converter but I prefer having double the size on everything.
One thing is I have redundancy just in case something fails and I need to off load. I can always run off the buck converter in such a situation. The converter was "free", I was intending to remove it and use it for a FLA battery charger but this way I don't have to and will get more use out of it.
Our Montana has a hydraulic pump to control leveling jacks and 3 slideouts. Plus all the interior 12v. I haven't measured actual use yet but I'm guessing it's quite the load.Curious why you need 80a?

You can't guarantee that voltage on the output will match precisely and hence share the load 50-50 so you need to add a bit of wiggle room.In a 24 volt solar system, If you need more than 40amps in your 12v system (toy hauler), can you parallel 2 converters to get up to 80 amps?View attachment 50502
