Thanks in advance

• PS 0 Inverter disabled.

• PS 1 Inverter is set to Auto. It disables the power on/off button. This is factory preset.
• PS 2 Inverter is in search mode. Another auto mode, not recommended. It does turn on the inverter automatically but, only when it see's a >10 watt draw. If you have a TV, clock or Alexa plugged into the inverted outlet this setting can cause power interruptions to the device.
• PS 4 Inverter power button enabled. My preference. It allows me to turn off the inverter without having to exit the RV and use the battery disconnect.

Keeping in mind that the inverter must be on in order for the internal transfer switch to pass shore or gen power to the inverted outlets.
