    LED fl ashes once every 2 seconds (medium fl ash) to indicate it is inverting. The amount of time the inverter can be inverting providing power is directly related to the amount of AC loads that are connected and the capacity of the battery bank. © 2010 Magnum Energy, Inc.

  • Page 30: Standby Mode

    While charging, the unit may go into Charger Back-off protection which automatically reduces the charge current to the batteries. This is caused by: 1. The internal temperature is too hot – the charger automatically reduces the charge rate to maintain temperature; or, © 2010 Magnum Energy, Inc.
