OK, so let's take your first question -- actually two questions: a) Does it "blend", and b) you give a very specific example / scenario of what you mean by "blend" when drawing current / load from the inverter and using multiple sources (Battery and Grid). Your question is well articulated, this is fundamental to any ESS system. His response is "Yes", but instead of elaborating on the specific example and perhaps giving more examples, he fudges and starts talking about transformer vs transformer less designs, IMHO this is irrelevant. He then moves onto battery charging. also irrelevant, because you are talking about servicing a load from a blend of sources. It does not answer your question and the very specific example which you gave IMHO.I'm re-reading the convo yesterday and not quite sure which questions you feel weren't answered properly? I'd like to post these to him as I am seriously considering this inverter and want to make sure I ask all the right questions before I do so. I also hear you about the powerforum, my experience there hasn't always been as positive nor the community as supportive as here.
The answer to your second question seems to suggest that he hasn't taken a look at the datasheet either, otherwise he would have corrected you with facts. Your question was basically 25A X 48V = 1200 W so how does this make 8000 watts (assuming of course one battery at 48v). He refers to I=V/R formula but no facts or specific examples. Then he talks about charging again, when you are talking about load. I do not know the SOLIS, and haven't seen the datasheet myself, but there is an absence of a factual answer that specifically addresses your question.
Maybe I'm too fussy though?
