First of all, apologies for the late response, just other things to do.
Well, what it primarily does is take input 1 and add it to the output,
I have asked this question before if anyone knows what is set to wrong, to my dealers, Disvent Barcelona as the Dutch dealer Top systems, they all do not understand what is happening, they quickly refer to the fact, yes, that is why we install a Quatro that has 2 inputs and not 1.
Normally that is nice, but in times of software there is no reason to have physical ports, at least not more than that you are actually going to use them.
So I have enough with 1 input, it is either shore power or the generator.
There are no more tastes and needs. but the generator no longer corrects the calculation, if you want to look in the system remotely, no problem, then I think I can easily demonstrate it. Request by PM?
