Diversion Load

These resistive loads enclosed in vented aluminum boxes can be used in 12-, 24 and 48-volt diversion regulation systems. The aluminum box may get very hot in operation. It should be mounted on a nonflammable surface and should be at least 12" from any flammable material.

HL-100 is shipped as a 4-ohm resistor and can be reconfigured as a 1-, 0.5- or 0.25-ohm resistor by easily changing connections in the terminal block. HL-75 is shipped as a 3-ohm resistor and can be reconfigured as a 0.75-ohm Resistor by changing connections in the terminal block. See chart below for diverted amps at various voltages.

2-year warranty.

Diversion Load Information

In most hydroelectric and wind-powered battery charging systems, the charging source cannot be disconnected from the batteries while running without the possibility of damaging them from over-voltage. The typical way to regulate battery charging voltage with this type of generating system is to use a "load diversion" type charge control. The Morningstar TS45 and TS60, the Xantrex C40 and C60 and the Outback MX60 can be configured for this mode of charge control. A diversion-type charge control also may be used in a PV system. If the array is much larger than necessary to charge the battery, excess power can be used to heat water by using a water heating diversion load. In operation, when battery voltage reaches the full charge setting in the charge control, it begins to divert power to the diversion load. The control uses pulse width modulation to turn the load on just enough to keep the battery voltage from rising further. The critical requirements are that the diversion load can dissipate more watts than the charging source can deliver, and that the maximum amperage that the load can draw is smaller than the maximum diversion rating of the charge control. We recommend that you do not use a load that draws more than 75 percent of the maximum rating of the charge control. For example, if the charging source can deliver 20 amps at 24 volts, use a 30 amp diversion load with a 40 amp or larger charge controller.
