Has anyone found a way to write to an Enphase IQ (or IQ gateway)?
I found that the IQ can be setup to limit the output power to the grid. But that is a static thing, what an installer programs when the PV system is installed.

I also have an inverter/charger with a batterybank.
It would be nice, if the grid failes, my battery is still charged. But I then have to limit the PV output if my loads and/or charger reaches the maximum power.
So, the PV output power should be adjustable…
