The 440 amp charge controller with divert relay can be used with our divert loads (divert load sold separately). Some diversion loads include, wire-wound resistor style, DC water heating elements, our room heaters, or simple plug in grid feed inverters.
This 440 Amp 10,000 Watt diversion controller features an LED display to let you know the battery voltage.
About 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, 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.
Several schools of thought on the subject:
Why? When you remove the battery level voltage from a wind turbine and send it's power directly to a load, then it sees for all practical purposes a short circuit (depending on the resistance of the load and lead wires.) This may cause the turbine blades to slow dramatically and in some cases bring it to a halt. This braking action can cause heat build up in the stator if it is repeated every few seconds or so (if the battery is just a little over the top). When you allow the turbine to see the batteries, along with the load, the turbine remains more within it's design realm -- always a good thing. The internal relays are configured to dump the batteries along with the source, but if you desire to disconnect the source from the batteries and send it to the load directly, simply utilize the N/C contacts of the relays as well.
