Diversion Load Types

Regardless of the type of diversion load you decide to utilize, make sure that the diversion load can handle all the power the charging system is capable of putting out. Paralleling heater elements (whether open air or water heater) will allow more power dissipation.

A good rule of thumb is to not have a combined charging source greater than 80% of the diversion load controller’s current handling ability.

For example, if a Xantrex C-Series, 40-amp diversion load controller is being used, do not place a combination of charging sources which are capable of putting out more than 32 amps (80% of 40 amps) on the load controller’s circuit.

Sizing a diversion system this way allows a safety margin for unusual conditions (high winds, high water flow, etc.).

It is not recommended that light bulbs be used as diversion loads for a couple of reasons:

1.An incandescent light bulb has a substantially lower cold filament resistance than when it is on. This means it draws more power (up to five times) to start the light when it is cold than once the filament has warmed up. Even a 40-watt light bulb may have an in-rush amperage at turn-on of 200 amps. This could cause the load controller to shut down.

2.In the event a light bulb load burns out, a smaller-than-necessary load will be present, and the excess energy will have nowhere to go.
