WESTERN HARMONICS Greenhouse Exhaust Fan Kit

The system features an integrated thermostat, meaning it is designed to activate automatically when temperatures rise above your set threshold. This ensures efficient energy use while maintaining the climate your plants need.

The 30Ah battery is sized to provide reliable backup during overcast days or short periods without direct sun. While exact runtime depends on your specific temperature settings and how often the fan cycles, it is engineered to bridge the gap during typical cloudy weather.

For most standard hobby greenhouses, 20 feet is sufficient to reach from the fan unit to the solar array placement. If your structure is exceptionally large or the solar panels need to be mounted far from the fan, you may need to source additional compatible cabling.

Yes, the kit is a complete solution. It includes the necessary solar panel clips, a parallel MC4 connector, and a battery box, so you won't need to purchase additional hardware for the basic installation.

A 20-inch fan is typically effective for small to medium-sized greenhouses. To determine if it's right for you, calculate the cubic footage of your greenhouse and ensure the fan's CFM (cubic feet per minute) rating aligns with your need for a complete air exchange every minute or two.
