Need to replace/repair circuit board for Whisper 200
I need to replace/repair the printed circuit board in the charge controller for a Whisper 200. Looking for a source to get a new board. I have contact many suppliers/dealers, including McDonald Solar in Colorado, with negative results. Hoping to find someone with a new board. Several repair facilities have quoted a minimum of $250.00 for repair. I believe that, when available, the new boards ran about $100.00. Sure would like to get this unit back on line. Any suggestion/leads would be very helpful. Thanks. Tom.
