Built-in grid inverter controller
The Built-in grid inverter controller CTW-1.5/2KS (V1.0/V1.5) developed by SENWEI. but now it have expanded to 3kw 5kw 10kw 20kw and 30kw 50kw;
This device is used for grid-connected operation of small wind turbines (WT):
CTW-1.5/2KS-V1.0 is suitable for SW-1000 wind turbine,
CTW-1.5/2KS-V1.5 is suitable for SW-1500Wp or SW/SWT-2000Wp wind turbine,
CTW-WGI-3KS-V1.2 is suitable for SW-2500Wp or SW/SWT-3000Wp wind turbine,
CTW-WGI-5KS-V1.2 is suitable for SW-5000Wp or SWT-5000Wp wind turbine,
CTW-WGI-10KS-V1.2 is suitable for SW-10kWp or SWT-10KWp wind turbine,
CTW-WGI-20KS-V1.2 is suitable for SW-15kWp,SW-20Kwp or SWT-15KWp,SWT-20KWp wind turbine;
which means the energy generated by the WT is supplied to the connected grid. Therefore the Built-in grid inverter controller converts the speed dependent AC/DC voltage of the WT into a grid- compatible AC voltage. For this process grid voltage is necessary. In the event of a mains power failure or when the WT generates more energy than the Built-in grid inverter controller can feed to the grid, the integrated intelligent electronic break system will automatically trigger, inverter will auto rest after a while when gust wind passes, and system will start to generate electricity again.
Features
1> Controller&Inverter integrated machine (only for wind power generation)
2> MPPT included, and 30 track points settable
3> Complete protection functions.
4> RS232/RS485/GPRS monitoring modes optional. (GPRS monitoring can be used on app as well)
