This is a concept most people don't "get" at first (including me, when I first installed my system). If you don't have some place for the power to "go" - loads such as your mini split, or batteries that need to be recharged - your panels just won't produce it.
Example: I installed panels that would produce 1260 watts max in a small system, and started started with a 100AH battery that I had fully charged before I installed it. When I turned the system on I was only seeing about 100 watts produced by the solar (because that's all the load that I had running). I thought something was wrong, and started checking everything (which looked fine). I ended up plugging in an electric heater, and saw the solar production soar. A cloud came over and the solar production dropped dramatically, but the heater kept running as the inverter used the battery power. The cloud went away, and the solar production soared again. I unplugged the heater and the solar production remained high for a while, until the battery was recharged, and then it dropped again, despite being in full sun. And then it dawned on me, that this was a feature, not a bug. Solar production occurs only when there's a need for it, either loads to be immediately used, or batteries to be recharged for later power.
Right now, my 1260 watt system is producing only about 550 watts despite being in full sun. There's about 30 watts of constant load from the inverter and related equipment, and about 350 watts from a small air conditioner, and the rest is being used by other loads and a little bit of "topping off" current into the batteries. When I turn on my computer monitors it'll go up a bit, and if I plug in a vacuum cleaner it'll soar. But otherwise, only 550 watts is all that's needed, so that's all it will produce, despite being capable of much more. Rather elegant and a bit of a life lesson in there somewhere, when you think about it.
