Understanding Grid Parallel topology and possible deployment MultiPlus-II

Hi, I am trying to understand if the parallel deployment of the MultiPlus-II 3000W

In the documentation we get this picture.

My question is in normal mode, where grid, solar and batteries are available, would the inverter back feed power based on the current sensor from solar to prevent power draw from the grid (up to 3000W) ?

If the overall system load exceeds MP supply (such as my cooker, ev charger, electric show etc) does it just feed what it can and the rest of the supply comes from the grid ?

Here is my planned deployment, I have excluded AC isolators, Breakers, surge protectors from the diagram for simplicity sake.

HB - henley block
CU - consumer unit
CS - current sensor

Hi
Yes to both answers, multiplus 3k is 2400W (3000VA)

Thank you :slight_smile:

Hi, I just watched a video that outlined that AC-IN is actually bi-directional, in this case I wont need to plug in AC-OUT 2, is that the case? Cant find it in the manual.

Yes both are bi directional, only ac out 1 will be powered during grid outage

So in grid parralel topology, when grid fails there is no power to your house, only everything on ac out 1 can be powered

Your drawing is not ok, you can not connect multiplus ac in and out1 and 2 together! Keep everything separated

In true grid parallel, only connect the ac in, not the ac out, if you want to power your house (or part off your house) connect those loads to ac out 1

I suggest to contact a local dealer on system design, as per community guide lines
