For Solar & Wind Hybrid 24V Systems

Introduction

What is a SolarWind Hybrid RX Charge Controller?

GreenergyStar SolarWind Hybrid RX is he most advanced charge controller in the market today. Unlike other hybrid controllers, this multipurpose device is designed to work with Southwest Windpower's Air-X, 403, and 303 plus other 24V AC/DC turbines and solar panels. The SolarWind Hybrid RX has utilized microprocessor based control electronics, sophisticated monitoring software, high quality finned aluminum casing and an intuitive LED display design. It is designed to work with the GreenergyStar branded grid-tie inverters to send renewable energy generated by Air-X, 24V AC/DC Turbine and solar panels back to the grid in a stable, controlled and safe manner. The following list will summarize its major features:

Features:

1. Hybrid system designed to work with Southwest Windpower's Air-X, 403, and 303 plus other 24V AC/DC turbines and 24V solar panels
2. Compatible with 24V grid-tie inverters
3. Maximum power: 1500W (rated at 54V & 30.0A)
4. System Voltage: 24V Nominal (see input / output sections for range)
5. Microprocessor based control electronics to control charging, outputs and dump load
6. Dump load utilize Pulse-width modulation (PWM) switching technology to recover power during high wind periods
7. Manual Braking switch to isolate wind turbine from the system.
8. Intuitive LED Display to reflect system status
9. Keeps battery in an optimum charged state
10. Prevents overcharge and over-discharge
11. Internal diode to prevent reverse current to solar panels or wind turbine at night
12. High quality finned aluminum casing to protect the interior and dissipate heat

Input Features:

• Operating voltage & current on all terminals: 23V ~ 54V, 0A ~ 27.5A
• Maximum input voltage & current on all terminals: 60V , 30A
• Withstand voltage: 65V (anything above will damage controller)
• Stand-by power consumption: 0.1W
• AC Turbine: For 3 phase AC turbine. The 3 wires from AC turbine can be connected to the terminals in no specific order. Built in rectifier will convert AC to DC. DC Turbines without a built-in dump load are connected here as well to utilize the controller’s dump load circuit. If your turbine is 3 phase AC to begin with, it is highly recommended to leave it as AC instead of converting it to DC just to save one strand of cable because doing so will cause larger voltage drop and less power output. The TURBINE LED will turn Green when there is an active input source.
• Solar: The SOLAR LED will turn Green when there is an active input source.
• DC Turbine: Reserved for Air-X / SunForce MPPT unit (only) since these generators have built-in dump loads and need to utilize the Stay Online feature. The TURBINE LED will not turn on since the Air-X has its own (red) charging LED. The Blue CHARGE LED will turn on when there is power coming in from the inputs.

Input Protection & Specification:

• Manual Turbine lock to force dump load to turn on
• Pulse Width Modulated Dump Load
• Stay-Online Feature to keep Air-X up and running in low battery condition
• Reverse Polarity Protection
• Night Time Reverse current protection to prevent current going into wind turbine and solar panels
• Over current Protection (30A Fuse)
• Efficiency: Maximum 98%+

Output Features:

• Operating output current: 27.5A
• Total maximum output current: 30A
• Maximum current on individual output: 10A
• Voltage tolerance: +/- 5%
• Maximum Output Power: 1500W (rated at 54V & 27.5A)
• Output starts when inputs are above 25V
• The OUTPUT A, B, C LED will turn Orange with respect to each output.

Charging Features:

• Battery is an input and an output at the same time
• The CHARGE LED will turn Blue indicating battery is being charged
• Overcharge protection Cut off voltage: 30V
• Over-discharge protection Cut off voltage: 22.8V
• Recommend using deep cycle batteries if possible
• Normal lead acid batteries are acceptable as well
• 3 charging modes: Continuous charging, Pulsing, Trickiling.

Power Supply Modes:

When input voltages are lower than the battery's voltage, the battery will act as a supply to all outputs. Power to all outputs will be cut when the battery has drop down to 22.8V

When battery voltage is below 22.8V and input voltages is under 18V, even though all outputs will be cut, the charge controller will still send electrical pulse to the DC input terminal every 5 - 10 seconds as indicated by the pulsing Red AX SIGNAL LED. This is necessary for Air-X's internal controller to stay on. Since the Air-X will not wake up on its own, without these pulses, even if wind starts blowing the Air-X will free spin and no power will be generated.

Warning: Controller will get damaged if polarity of battery is incorrect

Protection Features:

Dump Load

• MUST be connected at all time to protect the charge controller, no dump load = no warranty
• Requires a minimum of 5Ohm 600W resistive load to be connected to the dump load terminal
• Dump load activates when AC Turbine is >= 54V
• Unlike conventional dump loads that short circuit on activation and drop outputs to zero, the SolarWind Hybrid RX utilizes Pulse-width modulation (PDM) switching technology to only dump what is necessary and conserve the rest.
  (refer to Figure above)
• Activating dump load will slow down the AC turbine and reduce voltage spikes.
• Over voltage protection: All outputs will be cut when input voltage is over 60V. However dump load will stay on.
• The DUMMY LED will turn Red when the dump load has been activated

• Manual Turbine Lock is used to force dump load to fully turn on (ie: short circuit)
• Useful when it is necessary to isolate AC wind turbine from the system (ie: during installation or maintenance)
• Turbine lock is the red switch at the top-left corner of the Output Face (refer to Figure 1 on page 6)
• " | " - locks turbine
• " 0 " - unlocks turbine
