This product is designed for installation on asphalt shingle roofs only. Please call Technical Services at 800-211-9612, M-F, 8A-5P, EDT, for any additional information needed.
Thank you for contacting MasterFlow ... It is possible to place a switch on the AC side of the inverter (not the solar DC side). Not recommended but possible. If you would choose not to have the AC side of the fan to operate, I would suggest a higher set point for the on position of the thermostat. Set the on point to 120 degrees F and the AC side would run only if the attic temperature exceeds 120 degrees F. Please call Technical Services at 800-211-9612 with any additional questions.
