KEEPS BATTERIES FROM OVER CHARGING. A MUST FOR WIND OR SOLAR. Everything mounted, pre-wired, ready to go! Easily saves several hours of work and frustration. This fully wire d unit provides a very efficient interconnect environment.
440 Amp, 10,000 watt - Diversion (Charge) Regulator. With Two High contrast Meters. Fully wired, ready to go for both wind and solar. Works directly with 12, 24 and 48 volt systems. Use this controller to regulate and prevent battery overcharge in.Some of the key features of this controller are. Microprocessor controlled -- This is very important for both stability and functionality. User changeable settings -- Several controllers on the market set the dump level, and that's that! 440 Amps, up to 10,000 watts.
Works directly with 12, 24 or 48 volt systems. - The relay contacts can handle open collector voltages of up to 120 volts. High Contrast LED battery voltage.
Several controllers do not tell you what's going on - This one does! High Contrast LED turbine amperage meter. Meters can be shut using the on/off switch. Two factory installed, fully wired D/C breakers and disconnects.
Entire unit is wired and ready to go for both wind and solar. - Ever wonder if your controller & load are working OK? Large (8" x 12") solid steel enclosure, with multiple conduit knockouts. Large enough terminal blocks that you can actually terminate large wire See notes below. The electronics are fully isolated from the enclosure, no ground loops.Draws almost no energy while monitoring all electronics. Must use some power to work -- this is a miser. Some specifics about the points made above. The microprocessor is the heart of the controller. It is given the battery voltage and the user changeable trip points. This information is analyzed and acted upon. The Battery level is checked, and based on that info. The Green LED flashes or is illuminated as follows.
(One) Flash indicates the battery is less than 12 volts (12 volt system - Double for 24 etc). (Two) Flashes indicates the battery is 12 to 12.5V. (Three) Flashes indicates the battery is 12.6 to 13v. (Four) Flashes indicate the battery is 13.1 to 13.5V.
(Five) Flashes indicates the battery is above 13.5V but less than 13.9V (Settings are adjustable). Steady green means the battery is full. The red LED is illuminated when the battery is being dumped at 14.5v 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. By simply turning a simple potentiometer with a small screwdriver, you can quickly adjust the trip point.
Note: 440 amps is not continuous, but is limited to 20% duty time. If the HVA receives a voltage spike above 104 volts, it will enter a protective state at which time it will shut power off to the board and light the red LED in the top left corner. To clear this condition, ALL power must be removed from the unit for 5 seconds.150 amp heat activated breakers have been installed to limit continuous current to 150 amps. The solenoid in this unit has been tested to over 440 amps. We have installed two 150-amp breakers as a standard configuration. This allows for 9000 watts of wind power in a 48-volt system, 4500 watts in a 24-volt system and 2250 watts in a 12-volt system. Solar systems should be designed for no more than 125 amps continuous current. The enclosure is heavy gauge, solid steel, ready to mount.
- No plastic, no junk, simple and rugged. This Hoffman pull box is perfect for terminating larger wire. It has multiple knockouts on each side of the box. The box measures 8.25" x 12". The electronics are fully isolated from the box.
Several schools of thought on the subject. The source of power wind turbine, solar panels etc. - should remain connected to the batteries while the dump is active. The source should be diverted to the load directly and disconnected from the batteries. We happen to believe that is far better to leave the wind turbine connected to the batteries at all times.When you remove the battery level voltage from a wind turbine and send its 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 its design realm. The internal relay is 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 relay as well.We'll be happy to send you a diagram -- this is a very simple to accomplish.
