Every starting value is invented, not vendor data. The defaults are the readings a meter with a reversed grid CT would show for the page's invented day. The tool assumes one grid meter at the main feed, a correct solar reading, and consumption = solar + import - export. If the rating set in the meter differs from the CT fitted, each grid reading is scaled by fitted rating / set rating. It cannot tell which case is true: use a night check on site. Type 2500 or 2,500; 2.5 and 2,5 are read as decimals; a value like 1.000 is rejected as ambiguous.
