At this stage I would rather not send anything back at all to the grid if there is another solution.
Sofar replied the following:
While we have had a new firmware to support unbalanced load. Buy electricity for a certain phase and sell electricity for a certain phase to achieve the maximum power generation.
For example: Load Power 2.5K/1K/2K -------- Reality output of inverter (2.5+2+1)/3=1.833KW : 2.5K(1.833+0.6..)/1K(1.833-0.833)/2K(1.833+0.167)
So my understanding in the case above, as Im not sending back to the grid, I would only get 1.8*3 = 5.5kW total.
My goal is still to be able to reduce my day time grid consumption to 0 and still really cant see how this is possible.
If I use 3 single phase inverters, i guess it will be split 3 * 2.5 kw. So if one phase requires 5 kw, I will again be pulling 2.5 kw from the grid. is this correct?
What is the best solution to be able to use the full solar capacity I have?
