Hello!
I have an 80 watt solar panel with 10 amp regulator and a 119 amp hr battery.
I purchased an aerator for a pond and was told it was 12v. I checked the manual and said 120 AC and 12v DC and 25 w consumption. Great ...i thought.
It comes with a transformer and on that it shows output 12v 2.5A 30VA
On the air pump itself it has a sticker and that shows PRIM. AC 120 V / 60 Hz Sec. AC 12V / 60 hz Pmax 25W
================================================== ================================================== ==================
I tried just out of curiosity to run it on 12v solar battery, nothing happened. I hooked up an inverter and that made it work though i feel not as strong as when i plug it to the mains. Maybe that is because the inverter has a modified sine wave?
1) So what do i do here? I mean it says 25 W and 2.5 A but based on values of the transformer that comes with it, i believe this thing uses more like 75 Watts and 5 amps?
2) Is their such a thing that can convert 12v DC to 12v AC? I find it a waste to go from 12vd to 120 Ac and back down to 12v Ac
3) If i get an inverter, probably only option will i be fine with a 100 or 150 Watt inverter? I found some but then i see it states 0.9 Amps 100w max continuous. Even a 500 watt inverter also mentioned 0,9Amps. How is that going to work if i need 2.5 A or more?
I plan to run it only in daytime or only at night and charge in daytime not sure which would be better. Assuming 25Watt i can use it in daytime but if it is more like 75 then ibetter just use it at night a few hours.
