    I need advice.... I seriously need back-up power urgently. It feels I am really gambling with "luck" now. I have a generator as back-up power now, but it means nothing if I'm not here to start it or if the power goes off at night and I dont wake up :sweatdrop:.
    My tank setup is a 1200 liter (DT + sump + display refugium). What I ideally would like is to have a UPS to keep the return pump running until power comes back on or in worst case scenarios, till I can start the generator. The return pump is an EHEIM 1262 (900 GPH).
    I know one can build amazing back-up systems but what about buying a "ready made" UPS/system capable of doing the job.
    Any suggestions on what to buy and where to buy?

    Most important, your return pump must run. Lights can be out, skimmer be out, heaters for 4 hours no big problem. Actually you only want your surface to move, to allow better oxygen exchange.

    all the rest you can sort out when you get home and start the generator.

    Tagging along. I think is a potential problem for many of us.

    I'm tagging on this one too. Our power went off last night but we never woke up. When I looked at the light timers this morning I realised that the power was off for over 3hrs. Thankfully all our creatures look fine so far.

    Hi Helga

    I also have a geni a 5500 and also have to start it myself.
    What you can do is to get a electrical dude to wire the geni for you if the power fails it starts automaticaly.

    But for the you must have a geni that has an electrical start.
    Cos then they add some unit into your db and some solinoid or something.
    Then when the power trips the solenoid kiks in and starts the geni.

    Oh ja, i think that setup is something like R1000 - R2000.
    a bit expensive but it works.

    Hope you come right.

    I have a 1200w inverter with 2 deep cycle batteries and it's given me so much peace of mind. I have linked my return pump, one circulation pump, Pellet reactor and my ATU to the inverter. Our power dips and goes off for short periods at least twice a week and even sometimes a few times during the night. The inverter switches on automatically if there is a problem. It's expensive but if you take into account the cost of your fish and corals then it's a worthwhile investment. DallasG can help you out with prices.

    Oh ja, dont try the PC ups route.
    Ive tried it. A 600va Proline PC ups, take out the normal battery and connect a Deep Cycle battery to the UPS.
    So backup power with longer time cos youve got a deep cycle one.

    One problem.
    It worked great until it got to hot and some caps fell out the pc board.
    So ja, i tried puting them back and boom.
    Something else poped aswell.

    So dont go that route.
    Unless you go buy yourself a lekke size and just hook that up to your overflow and pumps that has to run like RiaanP said.

    But thats also like in the R2000 +-

    I use these guys www.homebackuppower.co.za.

    The unit is "plug and play", also protect my equipment agains surges (but has another surge protector in my mains plug).

    With the 102 Amp Silver Calcium (no, do not put it in your tank) battery linked to your pumps only, it will run for hours, and you can always swap the battery out with your car battery if it runs low, but think the 50Amp will be more than enough for normal failures.

    It is fully automated so it charges the battery when the power comes back on. Found the 600W unit more than enough for my Nano.

    The housing units they sell (plywood) as an extra is not sexy. The company is great, deliver to your house (they did to mine in Jhb), and after sale service has been great. Mine is four years old and have no problem. Lived through the Eskom crisis without a blink. Also got alarm features that warns you when the power is low and the battery runs out (could be louder, but has woken me up a few times).

    Below are the prices on their website, may sound a lot, but compare to even a modest stocked tank's livestock it is a no brainer:

    Kevin Range Back-Up 220 Volt Home UPS Power Units

    UPS Unit Only

    Prices are subject to confirmation
    • 600 watt UPS - R2500-00
    • 800 watt UPS - R3100-00

    Larger UPS Units for Home or Office are are available.

    UPS Backup Power Unit Extra's:

    • 50 Amp Sealed Lead Acid Battery ( Maintenance Free ) - R850-00
    • 102 Amp Hour Sealed Silver Calcium / Lead Acid Battery ( Maintenance Free ) - R1650-00

    a normal ups cant power pumps due to the electrical wave of the energy output, it can power heaters and lights... i found that out after buying a ups that i have no use of... for some reason you will need a ups that is a true sine wave ups and true sine wave ups is triple the prise of a normal ups... google true sine wave, and look up on youtube, true sine wave ups...

    i know it sucks big time...

    do anyone know off a return pump that will work on a non true sine wave ups?

    Those ups's sounds expensive
    To dot his for under R1000 All you need is:
    Electronic car charger, battery(size pending on load and duration),relay and a cheap inverter.

    Modified electric power is what one finds coming out of most cheap inverters and UPS systems. 220 Volt electric motors are not designed to run on a modified sine wave and will normally not run in both directions ( eg. open and close a gate or door ). Modified sine waves which allow a motor to turn or run, will cause the electric motor to operate at a higher temperature as the modified power supply is not as efficient as a pure sine wave power source. Modified Sine wave that can run your fridge or freezer causes fridge or freezer motor to make excessive motor noise and become irritating to one.
