I find it hard to get information on how the Multiplus works. I own a Multiplus 48V 5000VA 70A and for a long time I thought that the maximum current draw from the battery was 70A while it seems it's in fact close to 105A (5000/48). I also thought that the maximum output power was 4000W(5000VA) but on the enclosure it's written "AC transfer capacity 100A". Can the Multiplus deliver more than 4000W if it has its AC input providing the needed power to compensate?
My goal is to extend the system because I am frequently overloading it but I cannot extend the battery pack because I don't want to mix different batteries together. I'd prefer to create a second battery pack. Something like in the following schema :
The second multiplus having a n AC transfer capacity of 1000A, it is more than enough to transfer the 4000W from the first Multiplus and produce in addition to the second multiplus inverter a total of 8000W.
Will this work?
What can make the second multiplus overload?
