Suggestion on a power backup system

[Mrfish55]

Alang, I have had the 1800 for a number of years, the internal batteries finally packed it in, I removed the internal batteries and replaced with a couple deep cycle 12 volt units, bad news is it is no longer portable, good news is it used to power my tank for 45 min. tested it over the last couple days and got 17 hours and still had 10% reserve. and unlike the generator I do not need to be home to switch things over, when the power comes back on it automatically recharges the batteries for next time.

wow awesome! how did you set that up? I would love to know how to hook this in case mine ever have the same problem.

I have 2 deep cycle batteries doing nothing

I bought my Noma 400 watts at Canadian Tire when they were in special price for 59$. I regret not having bought 2 of them! Mine has been working flawlessly for about 3 years.

I bought a couple of the Noma 400W versions when they were $59. They are great. I run one and the other is still in the box. Just running my Tunze, I have gone for 8 hours without fail before. Not sure how long it would last if pressed though.

That is a good price, I paid $349 for the 1800w
The conversion was easy, opened up the case, removed the original batteries, extended the power cables, ran them thru the side of the case, closed everything back up and hooked up a pair of deep cycle batteries. works same as before but instead of 45 min run time I am now getting close to 24 hours and still have reserve. I am running 4 ps3 return pumps on it right now, thinking of putting the skimmer for the FOWLR on as well, don't really need 24 hours back up time and I am sure the skimmer plays a pretty big role on the FOWLR with the amount and size of livestock in there.
