BMU801 receives charging power from solar panels with 12 V nominal voltage or from an external DC power supply. When multiple input sources are required, BMU801 can accept input from 2 solar panels and one DC power supply simultaneously.

CAUTION Do not connect too high DC input voltage to the device. If the maximum input voltage is exceeded, the device will stop operating.
  1. To connect solar panels, connect the first solar panel to Solar 1 and the second solar panel to Solar 2.
  2. To connect a DC power supply, connect a cable from the DC power supply to DC in.
    When using external DC power supply, Vaisala recommends to install an external 10 A or 16 A disconnection device for the DC input.
