Application

This unit is used with Wind Machines to control the charge on a battery or to limit the output voltage on a wind generator when it is offloaded.

When a battery is full, or a grid intertie inverter goes off-line (for any reason) the power of the wind machine is diverted to protect the wind machine, battery and/or grid intertie inverter.

Unlike solar panels which are safe to leave in a open circuit condition, wind machines must always have a place to put their power when they are in the wind generating power. If wind machines have no or very little load and the wind is blowing, very high voltages and speeds are produced, damaging the wind machine and any equipment hooked to it. At Solar Converters, we have seen 250 V come from a 24 V "regulated" windmill.

Voltage Clamp (Dump Load) Controller:
Connection Diagram
This wind machine controller is virtually identical to the battery charge version, however, it has been modified to connect across the input of a grid intertie inverter to protect both the inverter and the wind machine from excessive voltage due to high wind ouput or the grid intertie going offline for any reason, including the currently mandated 5 minute start up requirements on the inverter.

Hot Water Heater Controller:
Connection Diagram
This controller is identical to the battery charge controller but uses its taper clamp abilty with added capacitors to maximze the power drawn from the windmill when used to heat water by keeping the windmill at its optimum blade speed as the wind speed varies.

Features

• Three state charge method (constant current, overcharge float charge
• 1200 Watt rating for 1000 watt windmachines>98%
• Ultra High Efficiency >98%
• Requires dump load which can be air resistors or hot water heating element
