G'day Solar Bozo's of old, lol, I've found that over the years the zephyr just doesn't pull enough cfm's. My solution was to use the Rule 240-24V. I buy them from amazon for around $70. These are generally used to vent boats prior to starting the engine and are US Coast Guard approved. I normally mount them to the top of the battery box and allow at least 12" before I vent to an outside wall. I buy a 4" - 3" rubber adapter in the plumbing department of Lowe's with the 4" attached to the blower, the 3" to sch 40 pvc piping. Make sure you screen the outdoor section to eliminate critters and flying pests. The cfm is around 200. Unfortunately, they do not offer a 48v unit so I just tap 24 volts off of the battery bank (Steve H is gonna kill me on this one, lol) and I use a 12v relay. For those inverters that don't offer a signal or dry contact the Morningstar four channel relay driver works. It has a ton of options. Hope this is helpful.
