The demand for reliable, off-grid power solutions is increasing, particularly in sectors like disaster response, remote infrastructure, and sustainable living. One notable system meeting this need is the tribrid mobile solar generator by 123eSolar, specifically the Alpha 10 model. Designed to integrate three power sources—solar, battery, and diesel—into a compact, towable trailer, the unit provides a versatile energy solution for a wide range of applications.
At the core of the Alpha 10 system is a 4,500-watt solar array. The array is made up of ten 460-watt high-efficiency panels that fold out from the trailer. The design allows the panels to be deployed in under five minutes, making it a practical option for situations where quick setup is necessary. Once expanded, the solar panels can be adjusted to a 30-degree angle to maximize energy capture, especially when oriented southward.
Power generated from the solar panels is stored in a 19-kilowatt-hour lithium iron phosphate (LiFePO4) battery bank. This storage component enables energy to be used long after the sun has set, ensuring continued power supply overnight or during cloudy conditions. In situations where solar input is insufficient or higher power demand is sustained, the generator switches to a 12-kilowatt diesel backup system.
The diesel generator is equipped with a 90-gallon internal fuel tank, with external ports available for connecting a secondary tank. This setup enables the unit to run continuously for up to 10 days without refueling, depending on load. The integration of solar and battery storage into the generator’s operation allows for estimated diesel savings of up to 60% compared to using a diesel generator alone.
All three systems—solar, battery, and diesel—are coordinated through a hybrid inverter and controlled via an onboard engine control unit. The unit also includes IoT capability for remote monitoring and system diagnostics. Electrical output is managed through a Camlock 16-series connector rated for 400 amps, along with a standard 60-amp circuit breaker.
With a total weight under 6,000 pounds, the Alpha 10 is light enough to be towed by most trucks and is compact for transportation. Its energy output is sufficient to power a 2,500 square foot home with air conditioning or operate remote telecom towers and construction sites. During daylight, solar panels power the system and recharge the batteries, while nighttime power is handled by stored energy and diesel generation.
Use cases range from residential backup during grid outages to powering mobile command centers, communications infrastructure, and water pumping systems in remote areas. The unit’s plug-and-play nature, combined with its fuel efficiency and rapid deployment, makes it suitable for both temporary and semi-permanent installations.
For those seeking a mobile, integrated energy platform that balances solar sustainability with diesel reliability, the Alpha 10 tribrid generator presents a practical solution.
