  Hi all, just curious, if the main power is down, how does the MultiPlus-II adjust the output of my solar inverter? Does it have a mechanism to deal with this scenario?

  Yes, when the mains are unavailable, the MultiPlus-II slightly increases the AC frequency. This increase is a signal for the solar inverter to reduce its output. This way it ensures that your system doesn’t produce more power than it can store or use, even during a power outage.

  In the absence of mains power, the MultiPlus-II system employs a frequency shift method to manage solar inverter output. It slightly increases the AC frequency, which is a recognized signal for modern solar inverters to reduce their output.

  This frequency adjustment is a form of indirect communication between the MultiPlus-II and the connected solar inverters, ensuring that the system doesn’t generate more power than can be stored or consumed during a grid outage.
