we've been setting the battery to charge overnight between 2-5am to take advantage of the lower prices, but for reasons i don't understand, the charging rate has been topping out at 1.18kwh, rather than the usual 2.4kwh we tend to get with solar.
Its been puzzling us why the battery was only half full in the morning, when i expect it to be nearer 3/4s full.
Any idea why the charging rate is drawing a lower rating at a time when the grid should be under less strain?
