Is there a device that I can wire into my solar panels and in different configurations, to monitor the out put, specifically watts. I have a Growatt inverter and I " assume" that when I pull the Growatt menu up I might see my 8,800 watt array at 205 watts. Again, I'm new to this, I'm hoping that is because my batteries are fully charged and little load from my home. I found devices but they all have 60 or 90 volt max. I'm at 400 volt. Help appreciated
