    Hi All

    I need some advice. I am trying to establish what I need to keep my return pump (Hailea HX5640 100watt) & maybe a small heater (150watt) going to maintain water flow & temperature during power outages & load-shedding.(3.5-4 hrs minimum)

    From what I've read I need an inverter(in this case 250watt would be sufficient),a deep cycle battery & a charger. Is this correct?
    Must the inverter have a pure sine wave output? Is there anything i have missed?
    Please guys I'm trying to get this sorted out ASAP!

    Thanks:)

    Dude, i showed you the ellies one in the other post. A bunch of reefers use them including me, R3000 and you are set, plug and play. Its lasted me 12hrs+ running a 3000lph return pump, one heater and a lamp in the house. Its modified sine but it HONESTLY does not matter if its not pure sinewave. Now will follow all the posts on how you need to spend 4k on a pure sine inverter bla bla bla, but you dont need it for the odd occasion that the power goes out ;)

    You would need a bigger inverter than that. It needs to handle the startup load of the pump etc which could be up to 6 times higher than normal. I would suggest a 600W inverter. Depending on tank size it will not be necessary to run the heater. This will just waste battery power.

    Make sure the inverter has a built in transfer switch. A intelligent 3 stage charger will work nicely but some inverters also come with a built in charger. If it does then you can skip the charger. A 102AH deep cycle battery will run your return pump for around 9 hours without issues.

    Pure sine VS modified is a very highly debated topic. Some say the modified sine will damage your equipment and others have been using them for years without issues. My reasoning is that if I have a R3000 return pump, do I want to run the risk of damaging it?

    Then it was also mentioned recently that eskom does not even supply pure sine wave.

    IMO a tank should survive a 3.5 - 4 hr outage no problem, unless you have a large bio load. I have survived a 10hour previously, but i do understand that each system is different. Personally for the price i would go for a generator back for the longer outages.

    I only put a 12v tunze return pump in with a 75ah batter in case of loadshedding.
    this system can last me 20 hours ad it automaticaly switches from 220v supply to the back up battery.

    I have installed a 12v bilge pump with relay switch to deep cycle battery. Pump was R300 at autozone. Pumps 1700gph at 6A - more than 10 hours on battery. There is also a smaller one of 4A.

    This is what I bought a while ago:
    http://www.bidorbuy.co.za/jsp/item/Item.jsp?Trade_TradeId=26881186
    It's a fantastic inverter. Puresine with auto charge, auto switch over the lot. I don't have a huge load on it, two return pumps for the Red Sea Max 130d and a vortech MP10 and I get many many hours out on a 105A battery. (I haven't had a power failure run the battery flat yet... know on wood)
    When I was doing research I read that some modified sine are better than others when it comes to pumps/motors (cheaper are probably worse?). Also they say that a modified sine isn't as efficient as a pure sine when it comes to the conversion to 220v, how much of this is marketing... I don't know.
    What I do know is that a fellow reefer of mine had a modified sine and his return pump hardly worked, ran hot so he has removed the inverter from his system.

    I also use the Ellies one (plug & play) & runs my pump & 300watt heater for 12 hours comfortably

    guys , im looking to power my tank in the event of a power failure,

    I could go for a 5.5KVA generator with AVR and run a couple of things in my house as well or i can just have a standby for my Tank.

    what would i need and where can i get them ?

    I run a 5 KVA gennie for my tank and it runs everything but the lights in the tank plus the TV and fridge no problem. The downside to a gennie and upside to a UPS is that the UPS kicks in as soon as the power goes in case you're not at home for a while and the downside to a UPS is that I doesnt power a lot of equipment unless you spend some serious tom on a super large one

    Maybe get both so you have the best of both worlds. A small UPS to power basics in case you're not at home and a 5KVa gennie to power everything else to sustain your tank properly. It will cost about R6000-00 for both.

    Now we just have to worry about the petrol attendants strike and not have petrol and electricity

    How about more detail on this bilge pump, sounds very economical..
