    Ok so this is a question for all the electrical boffins out there. This is what i thought...excuse my ignorance if i am wrong but i am just taking a quess here:

    I have 3 tanks

    One of the tanks (a cube) i am not too worried about as i have a plan there already, but have suffered quite a few times some electrical power cuts the past few weeks. One lasted for 10 hours.
    Now i do have a generator but was thinking about rather late at night to have the following running in case of emergency, just not sure if it will work..Please let me know your thoughts.

    I am running a Waveline DC5000 return pump on one tank and a Waveline DC3000 return pump on the other tank.Now what i want to do is use my 300w invertor plugged into my car's sigarette lighter and then have 2 cables connected to a 3 point plug... (plugged into the invertor) have my car idle while in use if need be. Then run each cable to each return pump. The specifications on the DC5000 pump says
    Model: DC-5000
    Input: DC24v 2.5A

    Wattage: 40w at Full Speed
    Flow rate: Max 1320GPH / 500LPH
    Flow Height: Max 3 Meters / 9.8 Feet
    Dimensions : 162mm x 104mm x 128mm
    6 Speed Controller Included

    and on the DC-3000 as follows:
    Model: DC-3000
    Input: DC24V 2.5A
    (Converted by AC100-240V 50/60Hz
    Wattage: 25W at full speed
    (Measured After Adaptor)
    Flow rate: Max. 800GPH / 3000LPH
    Flow Height: Max. 2.7 meters / 8.9 feet
    Dimension: 5.4" x 3.4" x 4.52"
    6 speeds controllers included


    Now if i add both it gives me a total wattage of 65W if both run at full speed. Will this setup work or am i missing something?

    so if power is down for 10hours you going to let your car idle for 10hours? :lol: think there is easier ways, rather connect the inverter to deep cycle batteries... just my 2c

    no wont run that for 10hours..but also dont want to go through putting the generator on in the middle of the night. So basically i just want to know if this is what i do have at the moment..(dont have funds for deep cycle batteries currently otherwise i would have gone that route), will it work if i connect it as explained above ???

    That will work,
    basically the same concept they use in 4*4 trailers. But there they do use a deep cycle battery and are not dependent on the car to charge the system all the time.

    Assuming that this is a car type inverter, from 12V car to 240V.
    If yes, then you basically build up a dedicated lead, from the inverter lighter socket to the tanks, Tank side got normal 3 point plug point, or similar points as to what the power cords have for the pumps.

    Power goes out at night. You run in nighties to car, plug in the inverter, start the car, plug return pumps out of the now dead plug points, and plug them into the special cable. Done.

    Need to open the garage door, with the back of the car towards the door, better still is to pull the car out half.

    But as a last resort, it is a possible solution. Not the simplest, as it will not work when you are away. And it might look funny doing this at one in the morning.

    Well this is all i wanted to know...Thx Riaan will let you check it out when i see you soon...!!! Yup car is parked outside anyway (no garage) so yes car is near the tank and i dont care what people think about me in nighties running naked at 1am either way...will draw less attention than running a generator anyway. Thanks for confirming this...

    is the inverter made for a car? if not you can damage your car , also if you run your car battery flat you stand a chance of damaging that.

    Then you shouldn't have to mod anything, use normal extension cords

    10h idling may get you close to the cost of a deep cycle battery.

    Here's an idea. Why not just bypass both power supplies, as they are rated 24V output you could achieve this by running two 12V batteries in series or even better get a meanwell 24v volt battery back supply and two 12V 17ha batteries. The supply will auto switch over to the batteries if the AC supply dies.

    I would not subject my car battery to the abuse!

    You can get deep cycle batteries from R800 and up.

    I run 2 deep cycle batteries in my defender.
    Run my 90L fridge off it and various 12v led lights.

    Standing for 2 odd days really drain the batteries, so I installed a solar system to charge the batteries when camping.

    Good luck with your quest!

    Mother earth is going to spank you. :lol:
    Running a car in idle for so long also damages it's sparkplugs and injectors. Try get a deep cycle battery

    Well uve guys have said everything, so I'll just tell u what I've done. I've got a 600w pure sine wave inverter connected to a 12v 105ah Deep cycle calcium Battery. When the power is on the inverter recharges the battery so no extra work for me. I'm running it on my tank that has a total wattage of about 200w. I tested the battery when I first got it and it ran my tank for 48 hours straight, and I stopped it there could have gone further.

    I thing u need to know about ur invertor. I don't advise you use the 300w one designed for the car as it is probably not pure sine wave and will short circuit and damage your pumps.

    Best of luck
