John P. Cable Mill - Great Smoky Mountains National Park

Customer goal:

Use excess power to pump water to large storage tank to fill needs for Cable Mill area with limited daytime generator use.

Description:

While we were installing solar at the visitor center, we discovered that the mill storage tank that keeps the wheel moving was powered by a loud diesel generator. We were able to utilize parts from the larger job to supplement the power at the mill and significantly lower generator time.

Collectors: FUTURE

Inverters: None: This is a control system designed to save power at a very low cost and to use excess power. PHOTOS are of the control system and wiring was completed later by the NPS team.

Result:

Mission accomplished!! When generator charges batteries at night, the tank is filled with the extra power from the generator until it is full. If the water drops to a low point a local generator adds enough water to get it to the evenings generator run
