PowerJam is our new rugged portable power station built for the off-grid life. Reserve yours now with an Early Access Pass and be first in line when production ships. Keep your fans, phones, lights, and tools running wherever the day takes you.
Western Harmonics started in 2012 with a simple idea: the sun that heats up a greenhouse or barn should also power the fan that cools it down. Since then we've shipped more than 6,000 solar-powered fans to growers, ranchers, and off-grid families across the country.
Every product is built to run hard in real-world conditions, without wiring, permits, or a power bill. Now we're expanding beyond fans with PowerJam, our new portable power station for life off the grid.
For complete solar system design and engineering, our partner Power Mosaics maps out panels, storage, and layout for your property.
