    Hi all,

    I bought this Backup Power system over the weekend.

    http://www.marineaquariumsa.com/showthread.php?t=42523

    I set it up to run my Reef Octopus Water Blaster return pump and 2 x Sun Sun pumps should the power fail.

    When I tested it only the Sun Sun pumps continued running, but the return pump did not. I suspect that the return pump cannot run off a battery back up for whatever reason.

    Can anyone shed some light on this and if it is a pump issue please can you let me know which pumps would work of this unit.

    Thanks,

    The output of the Tedelex intellipower is modified sine wave.
    Some pumps will run on modified sine and some wont. Some pumps will run modified sine one day and the next day it wont.
    It is recommended to run pumps off a pure sine wave backup unit.
    DC pumps like the waveline DC pumps can run off anything.

    Those are great backup units never the less but you may have to change your return pump.
