DC Pool Pumps

Sheet 1: system overview

The DC pool pump, drawn to scale

Sun to panels to controller to pump: on this path the SunRay hybrid runs 100% solar-powered, with zero electricity taken from the utility.

Kit pricing starts at $1,999

  • Ref 1: DC input100% solar from the kit's dedicated panels
  • Ref 2: AC inputAC is optional; dashed on the drawing
  • Ref 3: duty6-8 sun hours covers a normal cycle
  • Ref 4: loadup to 30% on the utility bill

Note A: the DC path

The panels connect to the controller, which drives the DC motor; no utility connection is part of this loop.

Unlike a grid-tie inverter, no AC is needed for the solar to work.

Note B: the optional AC path

Land AC on the controller and it takes over automatically when solar falls short, as with a spa at night.

Leave the AC terminals empty and the drawing still functions on sunlight.

Note C: expected result

Field results run $100 to $250 a month saved, scaled by tariff and irradiance.
