Some of the key features of this controller are:
* Microprocessor controlled
* User changeable settings
* Super High amp rating - **440 Amps, up to 10,000 watts. -- Uses the same relay as the SEA-440.
* 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 -- Measures 3 digits to the left of the decimal, 2 digits to the right.
* 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
* 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.)
