40 Amp Diversion Controller in Steel Gang Box

32.99 32.99 USD


SKU: C40-24SG

24 Volt 40 Amp Wind and Solar Charge Controller Regulator


Compact and economical diversion or disconnect controller that mounts in a single gang switch box (included).

Product Features:

  • Microprocessor controlled

  • User changeable settings

  • High amp rating

  • Battery status LED

  • Push to test

  • Heavy-gauge, solid steel enclosure (standard outlet box)

  • Long leads for easy termination

  • Can divert the source from the batteries to the load, or dump both the batteries along with the source

The microprocessor is the heart of the controller. It is given the battery voltage and the user changeable trip points.

The Battery level indicator illuminates as follows:

  • (One) Green flash indicates the battery is less than 24 volts
  • (Two) Green flashes indicates the battery is 24- 25V
  • (Three) Green flashes indicates the battery is 25.2 - 26V
  • (Four) Green flashes  indicates the battery is 26.2 - 27V
  • (Five) Green flashes indicates the battery is above 27V but less than 27.8V (settings are adjustable)
  • Steady green indicates the battery is full
  • Red indicates the battery is being dumped at 29V (or the charge source diverted)

The dump remains active for a minimum of 5 seconds, at which time it is checked by the microprocessor. If battery voltage drops below the "Dump Cancel " level, the dump is disabled, otherwise the dump is continued and rechecked every 5 seconds.

  • When you click the "TEST" push-button - the 5 second cycle is started (one time, unless the batteries are within the "Dump Start" and "Dump Cancel" zone.)
  • Settings are user changeable. By simply turning a simple potentiometer with a small screwdriver, you can quickly adjust the trip point.
  • Controller/Regulator is configured at 40 amps. There is nothing stopping you from adding more relays for nearly an unlimited amount of load capability.The internal regulator can handle 4 relays.

Load diversion: The basic operating philosophy of a diversion controller is quite simple. Monitor the battery voltage, and if it should rise to a predetermined level, connect a diversion load (or "Dummy Load"), of sufficient size, to the battery or energy source to prevent the battery voltage from increasing any further. This is a very simple, yet very effective way of preventing battery overcharging. All alternate energy systems should have some form of battery overcharge protection.
