Missouri Wind and Solar - 440 Amp HVA Charge Controller
12/24/48 Volt 440 Amp HVA Charge Controller Instructions and Troubleshooting
Our 440 Amp HVA Charge Controller for use with Wind Turbines, Solar Panels, and/or Hydro Systems is easily one of our most versatile, powerful controllers in our line of equipment. In our YouTube video below, Wyatt gives instructions on how to change the different settings and some general troubleshooting tips.
Some of the features of the HVA include:
Diversion-Charge Load Controller
440 Amp 12, 24 or 48 volts
High contrast LED dual volt/amp meters with on/off switch
Built in D/C Breakers
Factory wired for both wind and solar
10,000 Watts! 8 x 12 Hoffman Box
Reverse polarity protected
Wyatt also shows how to change the controller voltage, extended divert mode, and dump point voltage and what isn’t user changeable!
The HVA Charge Controller does come with an instructional manual that will be useful in setup and maintenance.
HVA Charge Controller Instructions and Troubleshooting:
The controller typically ships with the
voltage jumper pin
set in the 24 volt position, but can easily be changed to 12, 24, 48
volt or extended divert mode by removing and replacing the pin in the
trip point (dump point voltage) is changed by turning the screw head with a small screwdriver and light pressure.
Turning the screw counterclockwise will raise the dump point voltage higher
Turning the screw clockwise will lower the dump point voltage
Extended divert mode (EDM) can typically be left
unset until you are more familiar or comfortable with your system. EDM
basically holds the charge controller in a diversion and disconnect mode
for a longer period of time.
breaker is for the diversion load while the breaker on the right is for the wind turbine.
Manually trip the breaker by pressing the red button on the breaker.
Reset the breaker by gently pushing the red arm back up into place until you hear it click.
amp and volt meters are set to on and are not displaying:
Check the glass
fuse in the upper left inside the circuit board, as it may be blown.
If the fuse is in good condition but the meter is not displaying at
all or is not displaying correctly, turn the unit power to off
and remove the back cover of the meter. Check to see if the long black
chip has fallen loose from its pin and replace it if that is the case.
Firmly replace the back cover of the meter.
The fuse is 250 volt 2.5 amps
Always have the charge controller hooked up to the batteries and
do not connect wind or solar without having the controller connected to the battery bank.
If you do not, and the wind turbine or solar panels produce too high
a voltage, it will either take out the fuse, or, if the fuse cannot
handle the surge in time, it can do serious damage to the circuit board
If you have a disconnect between the charge controller and the batteries,
always disconnect your wind and solar before disconnecting the controller from the batteries.
