DC Fan Kits

Looking for a new DC Ventilation Fan? Solve your circulation issue with this solar direct solution!

Greenhouse

Manufactured locally for Backwoods Solar, these fans are designed to meet your needs every season in the greenhouse or with an attic install. Intended for use with 12 volt or 24 volt solar panels as low as 30 watts and up to 250 watts as well as in conjunction with 24 volt battery banks. They will also perform with 300+ watt, 72 cell modules with open circuit voltages of 44 volts.

The SF16 is protected from moderate over-voltage and thermal fluctuations and has been tested through a variety of panel and voltage configurations. The biggest advantange with this DC fan is the brushless motor. Motor brush replacements were common on previous fans, especially if they were run at high RPM’s. Without brushes, the SF16 will outperform other fans. The SF16 is not intended for use with 12 volt battery banks or AC power of any kind. 

We recommend four configurations for “small”, “medium”, and “large” applications. We have created pre-designed kits, with solar modules and mounting hardware for each of these configurations. Add two kits for intake and exhaust at either end of a greenhouse.

KIT #1: Includes a 60W solar module; a 16" fan that will run PV direct at 12V, and simple mounting hardware for flush mounting to a roof. This kit is capable of 2000cfm at full sun and is recommended for greenhouses or spaces from 2000 - 4000 cubic feet. Cabling from the solar module to the fan is not included, but can be supplied separately based on length of run.

KIT #2: Includes a 100W solar module; a 20" fan that will run PV direct at 12V, and simple mounting hardware for flush mounting to a roof. This kit is capable of 3000cfm at full sun and is recommended for greenhouses or spaces from 4000 - 6000 cubic feet. Cabling from the solar module to the fan is not included, but can be supplied separately based on length of run.

KIT #3: Includes a 150W solar module; 2, 16" fans that will run PV direct at 12V, 15' of MC4 cabling to run from the module to the fan, and simple mounting hardware for flush mounting to a roof. This kit is capable of 4000cfm at full sun and is recommended for greenhouses or spaces from 8000 cubic feet. Additional cabling can be ordered for wire runs longer than 15'.

KIT #4: Includes 2, 100W solar modules; 2, 20" fans that will run PV direct at 24V, and simple mounting hardware for flush mounting to a roof. This kit is capable of 6000cfm at full sun and is recommended for greenhouses or spaces from 12,000 cubic feet. Additional cabling can be ordered for wire runs longer than 15'.
