Temperature range
LICAP's ultracapacitor based retrofit solution replaces the existing lead-acid battery back-up system for pitch control in GE 30Nm and 20Nm wind turbines. Our solution is a drop-in replacement that is designed to fit in the same location as the existing batteries, and will not require any operating system modifications. We designed the solution to be common across the different pitch box versions with only wire harness, bracket and mounting accommodations.
There are 4 variations of the battery box (shown here). Wiring harnesses vary significantly between the A & B designs, with minor differences between the B1, B2, & B3 versions. Drop-in replacement cable and hardware solution adapts natively to all the OEM's component configurations without modification required.
The GE 20Nm battery box is shown here. There is only one version of the 20Nm battery box. Wiring harness will be similar to the existing harness and mounting bracket for capacitor charging unit (CCU).
