18A/24V 500 Watt Diversion Dummy Load Resistor Heater

18 Amp, 500 Watt, 24 Volt Diversion Load Center

Designed for use with Diversion Controllers


This Diversion Center Can be mounted on to a wall to provide heating as well as serve as a diversion (dummy) load.


These resistors have been selected specifically to perform as diversion (dummy) loads in solar/wind/hydro alternate energy systems. Unlike water heating elements, this unit does not need to be submerged in water or oil. It will operate in free air.

Each of the resistors we sell has been selected based on it's ability to dissipate a very specific amount of power (watts) with a very specific resistance value (ohms), at a very specific voltage. When used as recommended, they will not burn out, even under continuous use.

Please note. These resistors will become hot during normal use, please mount them away from heat sensitive objects and out of the reach of children.


The diversion load center consists of six resistors mounted directly onto two sheets of CNC cut, 16 gauge metal sheets (A left and right sheet). These two sheets form the electrical connection for the six resistors. Both sheets are mounted to a solid piece of ceramic board. Two terminals with brass nuts are provided for a solid connection to your wiring. The entire unit is enclosed in a Hoffman 8 x 12 x 4 enclosure with a vented cover


 Load specs per resistor.

   Ohms    Volts    Amps    Watts
10 24 2.40 57.60
10 25 2.50 62.50
10 26 2.60 67.60
10 27 2.70 72.90
10 28 2.80 78.40
10 28.5 2.85 81.23
10 29 2.90 84.10
10 30 3.00 90.00

Area in green is where most diversion controllers would be set to divert.
This Diversion Center consists of six - 10 ohm resistors. Each 10 ohm resistor will dissipate 2.9 amps at 29 volts. This is 84 watts/resistor. 6 resistors in parallel will dissipate 504 watts at 29 volts (17.4 Amps), or 540 watts at 30 volts.



This Diversion Load center is a perfect companion to a 500 watt 24 volt wind generator and our C80 or C160 controller.  Please see our other listings for 12 and 48 volt diversion centers.
