All In One Sky440 Charge Controller Board with Brake Switch and Solar Combiner Box


Starting From: $674.99

All In One Sky440 Charge Controller Board great for hybrid wind, solar and hydro applications.  This board is ideal for wind turbine and PV hybrid systems. Comes fully prewired to accept single/dual output wind turbines and solar panel arrays up to 63A. Sky440 charge control board features dual meters to display voltage, wattage, amperage and watts per hour for each charging source. Board features brake switch and dump load. This is a turnkey solution with simple inputs and long battery leads. We've taken the guesswork out of wiring the system together and have brought you an all in one solution. Fully assembled by Missouri Wind and Solar with tried and true products. 
Comes prewired:
  • to accept 2 single wind turbines or 1 dual through the brake switch and rectifiers
  • to accept up to 63 amps of solar panels through the pre-installed solar buss bar combiner box
  • with a diversion dump load for the wind turbine/s to keep them from over speeding
  • SkyMax 440 Charge Controller
  • Dual 3 Phase Brake Switch
  • Diversion Dump Load (4 Resistor Bank)
  • Buss Bar Combiner Box

Sky440 Charge Controller Features:

  • Dual meters:
  • Each meter displays voltage, wattage, amperage and watts per hour from each charging source.
  • Dual microprocessor controlled for stability and accuracy Multiple user changeable settings and trip points for many various system requirements and applications.
  • You can change the dump point voltage level, end of dump voltage level, and length of time in divert mode when end dump point voltage is reached (between 0 to 999 seconds, or 0 to 999 minutes)
  • Isolated Electronics Protection - Almost impossible to accidentally connect wind or solar directly to the circuit board
  • On board relay isolates electronics from back voltage spikes from large 440 amp relay. This is important to get the longest life out of the electronics. No one else has this!
  • High amp rating: 440 amps, 10,000 watts; 100 amps continuous for the solar side.
  • Can divert the charging source from the batteries to the load or dump both the batteries along with the charging source (dump load sold separately)
  • Connect both wind or hydro and solar at the same time
  • Reverse polarity protection
  • 100 Amp and 63 Amp 150VDC Din Rail Breakers
Brake Switch & Rectifier Combo Features:
  • Dual 3 phase wind turbine brake switch
  • Two 90 amp bridge rectifiers
  • Each switch will handle 2500 watts continuously

1200 Watt Diversion Dump Load (4 Resistor Bank) Features: 

This divert load resistor is for use to divert the excess power being generated when your wind turbine generator batteries are full and can be ran at 100% duty cycle due to the quality rib wound design. Protects your wind turbine from free spinning.
