I was playing today with some peltier elements 12v 15a

It was not what i was expecting.

The best they could do was 10 amp at 12v(rated 15amp!)

One was plugged into a psu that can deliver 60 pure amps! at 13.5v!

Still it asked for 10 amps at 12 v(3 of them at 26 amps at 12.0v)

I noticed the better you can get rid of the heat the more amps it wants to have.

But oke.

To connect 6 (x 15 amps) of them i must have a battery capable of 90 amps 12 v minimum to last one hour?

Right?

Second question:

To have that amount of power drawn from my power wall, i don,t want and like that.

How can i supply that amount of power from a solar panel to a battery to those peltier elements?

Basically a stand alone powerwall to feed those hungry basterds, fed by solar panels.

What kind of stuff do i need?

With best regards, and thanks in advance, Igora
