building a larger and more complex system (including 3Phase, Solar, CHP machine etc.) i would like to, by software, force the 3 MPII (one on each phase) to enter the 'ignore AC Input' state in order to make sure no power is feed back. The main parameter is the SOC which should drive that state change. I would like to avoid physical relays and cables and use the existing communication between the GX device (Cerbo in my case) and the MP systems. What is the best/easiest/safest way to accomplish this ?
