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 wired unit provides a very efficient interconnect environment.
440 Amp! 10,000 watt!! - Diversion (Charge) Regulator hybrid controller
With Two High contrast Meters (both Volts and Amps) Two D/C breakers/disconnects. 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: Solar Systems,Wind Systems,Hydro Systems
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!
◦Super High amp rating - 440 Amps -- 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. Connect multiple turbines and solar panels up to 440 amps worth at the same time! Max solar amperage in disconnect mode is 100 amps. Max solar amperage in divert mode is 440 amps. This is a huge hybrid wind and solar charge controller.
◦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.
◦Battery status LED
◦Push to test. -- 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)
◦Reverse Polarity protected.
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
1.(One) Flash indicates the battery is less than 12 volts (12 volt system - Double for 24 etc)
2.(Two) Flashes indicates the battery is 12 to 12.5V
3.(Three) Flashes indicates the battery is 12.6 to 13v
4.(Four) Flashes indicate the battery is 13.1 to 13.5V
5.( 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.
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.
High amp rating -- 440 Amps! -- 10,000 watts!! -- This is a MONSTER hybrid controller.
This controller is capable of handling the input from 166, 60 watt solar panels, or 10, 1000 watt wind turbines, or any combination of the two not to exceed 440 amps, 10,000 watts. This is a lot of control.
About load diversion. Several schools of thought on the subject.
1.The source of power (wind turbine, solar panels etc.) -- should remain connected to the batteries while the dump is active.
2.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. Why? 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 -- always a good thing.
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.
** 150 amp heat activated breakers have been installed to limit continuous current to 150 amps. Instantaneous current handling of this unit not to exceed 440 amps. **
Ready to go. built to last, right here in the USA. below photos show the HVA Charge Controller with optional dump load, disconnect, inverter and fuse
