Who hear has went from Large AC Pump like 3-6 amp pump to and Abyzz 200 or 400 DC pump ?

Looking for real power savings not guesses or estimates from people that have not made the switch.

And if you know, what is the timeline on ROI with going DC Abyzz.

Not Abyzz, but I went from a Sicce Silent 5.0 (AC) to a Sicce SDC 6.0 (DC) and it was 1/4 to 1/3 of the electrical cost. Paid for itself in less than 9 months.

Abyzz pumps are, well... the ultimate pumps. You're paying for more than just the electricity savings, ie: performance, reliability, warranty, peace of mind, etc.

Thanks but I'm looking for big pumps 6000 gph type pumps.

What about this pump here, is anyone running these and can give me an estimation on AC power consumption ?

I have a friend with a a400. I just texted him. He just said 400-420 watts on full tilt... so 3.5 amps. The pump that he replaced was 220/240v and a bit over 2 amps, or 4 amps at 110/120v. The a400 does not pump as much water, but is a bit lower wattage. He saves half of an amp, or so, with a tad bit less water.

The math is easy, but you likely are going to have to guess since neither of these are common around here. In Colorado, with a kWh being a dime, if you save an amp, or 120w, or so, then you save 29 cents a day. For a $3600 dollar pump, that is well over 10000 days, or more than 30 years. We have cheaper electricity than most, so you could save more. If you save 2 amps, then double the daily cost and cut the timeline in half.

I don't know where you live, but solar has an actual ROI if you live in a friendly place. I did this exercise a while back with my hot tub and tanks. Rather than trying to save an amp or two with a new pump, $3600 can go a long way towards providing much more power than this for the long haul. I know that you did not ask, but many do not consider this when it is plenty viable alternative.

Free bump in case anybody has done this.

This is exactly what I needed to make an educated decision, My MRC 6100 pumps only draw 3 amps and deliver a massive amount of water, About 5000 gallons an hour at 360 Watts. So going to the Abyzz is actually a worse choice.
This is great to hear as I have never loved a pump more than these MRC 6100's, I Run 2 of them.

Thanks a million for this response, and I am also going Solar, installing 55 - 400 watt panels on my roof to produce 21k of power to my house !!!!!!!!

Thanks Thanks Thanks

The solar will help you out a lot. I don't have small tanks, but they are not as large as yours, and I just got sick of worrying about a few watts here or there paying retail to replace stuff that is working... and risking that the new stuff is not as reliable as the old. It took some pressure off of me thinking about reefing and power.

In my house, even an energy hog like a Mag 12 at 110w (which I don't use, but an example as the worst case) versus an ACTUALLY good DC pump at 40w is like 17 cents a day. If the new pump is over $250-300, then I don't know how these get paid off in the timelines that people say. ...and I use AC Tunze pumps which are more like 50-55 watts vs 40, which is like a rounding error that you can never make up... and I get Tunze reliability. Plus, I buy them on eBay or locally when people are "upgrading" and I have a whole stash of super reliable backups that I got for around $50 each.

I am imagining the roof needed for 55 panels.
