The power consumption of the MXZ-3C30NA condenser will vary. First, the range will vary depending on how many units are connected, and the size of each. Mitsubishi sometimes releases data about the range, but has not yet done so for this product.
Real-time consumption will vary depending on demand from the zones. The inverter compressor can modulate its speed, which in turn changes its demand for electricity. Also, since the indoor units draw power from the outdoor unit, consumption will depend on indoor fan usage/speed.
