    So how about the other settings, do I need to set all the settings in each inverter or will the slave inverters automatically adopt the settings of the master inverter regardless of which settings you put into each of the slave inverters?

  • Post in thread: Which Solar Panels?

    You keep saying they are about the same cost, but they are 50% more than the ones I was looking at, not sure why you keep saying this unless you know where to get them for .32 cents a watt with free shipping.
