Line 176: Line 176:
   * The AC input voltage slowly drops before it is being rejected by the Multis. Typically happens in installations with a generator. Especially when combined with AC loads that increase their current draw when the AC voltage drops: by the time that the inverter/​charger initiates the disconnect, the current through the relays has increased well beyond the ratings, and is too high to open them.\\ __Solution__:​ Make the Multis or Quattros disconnect earlier: increase lower limit of AC input voltage in VEConfigure3. For example to 210 VAC. The factory setting is 180 VAC.   * The AC input voltage slowly drops before it is being rejected by the Multis. Typically happens in installations with a generator.
