Grid tie inverter switching controller. This controller can switch two different voltage grid tie inverters to get maximum wind power. Use a 250w GTI for low wind and 1000W 22-60GTI for higher winds. This controller can be set for switching from 0-90vdc by the user. It can also be used to switch from a battery bank to a grid tie inverter as well. Needs a constant 12vdc to operate. It has two real time meters that show AC and DC production. Amps, watts, voltage and Kwh. They each update ever second A Red led indicator light for switching activation. AC fuse 15a , DC fuse 1a for internal controls, and 1 duplex AC outlet to plug up to (2) grid ties into. Terminals for AC 120v input, 12vdc input, GTI DC input. 30 A rated terminals. Ties right off your wind turbine rectifier. Recommended 20amp 120vac hard wire dedicated circuit. Includes an 80amp 3 phase rectifier. If you are switching from batteries to grid tie i can build the system for that. You must tell me your full intentions so i can build the system to your needs. The box is made of ABS plastic for light weight mounting and cost effective but rigid. The controller is rated for 30amps at 60 vdc. I have tested (2) types on this system. Windy nation 750w turbine and a HYE. (HY Energy) 24V 1000W. The HYE is also know as a Wind Max or Sky Max. It will also allow your components to run cooler since it allows a higher voltage GTI to work in conjunction with the system. Higher voltage and less amps equals less heat and more power to harvest. If you are not savoy with electrical please consult with a licensed electrician. I assume now responsibilities on how you hook up this controller. I custom make each controller so you will have to specify your current system and type of wind turbine you have so we can make sure its the perfect controller for you. It takes about 4 weeks to custom build due to ordering components. Controllers may change in appearance however the listing for what is does is the same.. This is due to new R and D technology. This is a one of kind controller made in the USA. How it works: Set voltage dial from 0-90 v to switch between GTI’S. So lets say at 18v your system will switch from a 10-20vdc gti to a 22’60vdc GTI. This may happen at a 10mph wind. You will have to set up your switching peramiters according to wind speed vs volts. Once above the 18v the 10-30 GTI gets disconnected and allows the bigger GTI to take all the turbine power. Under 18v the 10-30 gti will reconnect. The main 22-60v GTI is always connected and the dump coil is connected to this GTI only. For a battery bank you must use a blocking diode so GTI does not take power from the battery bank. Set the voltage switch to your float voltage of lets say 14.1. The controller will disconnect the battery and send power only to the 22-60v GTI. Only two gti’s can be used. For a battery bank use a 12 or 24v bank The best efficiency system is a 24v ac output wind turbine at a 1000w with a 250w 10-30vdc input and a 22-60vdc input with the manufacture dump load resistor connected only to the 22-60v GtI For battery use a 12 v battery system replace the 250w10-30vdc GTI with the pos and neg from the batteries. Remember you can dial your switching at any voltage from 0-90vdc. Contact me with any questions on this one of a kind controller. Each controller is built one at a time due to them being custom made. It takes about 4 weeks to get parts. We build these by hand no fancy machinery. Every unit is hand crafted and tested. The item “Wind Turbine Controller Grid Tie Inverter. Custom. One of a kind.
