Smart Off-Grid Solar Trailer 

MOBISUN Mobile Off-Grid Smart Solar Trailer is a robust energy generation and storage system that harvests sun energy with solar PV panels and stores the power in deep-cycle tubular gel batteries. The electrical architecture including a Schneider Electric smart pure-sine wave inverter/charger is housed in a compact, lightweight aluminum dual-axle trailer chassis that has R12 value insulation and is sealed at NEMA 4X enclosure equivalent specs. The Mobisun has EMF protection and the internal environment is climate controlled through the use of an HVAC system to endure even the most extreme of environments.

For additional power generation, a MOBIWIND Low-Mount Vertical Axis Wind Turbine is integrated into the Mobisun with an easy deployed pole mount attached to the trailer chassis and electrical architecture for wind power harvesting. For telecom and other applications that require guaranteed 24-hour uptime and backup, a diesel generator as well as extra fuel storage is also integrated into the Mobisun.

On-board Internet communications through GSM/LTE or satellite allows for remote access into the Mobisun to control and monitor all systems to ensure optimal performance, easy trouble-shooting, location services and GPS tracking. By virtue of having on-board Internet connectivity, a WiFi hotspot can be made available to the surrounding area.

33 Kilowatt Hours of Energy Storage

To get an idea of how much power you might need in a day, see the list of AC appliance and hardware that you would use in an busy office in a remote location. Based on loads that add up to 7 kWhrs, the MOBISUN uses the stored power at night, or when the sun is not shining, for up to 2.5 days without recharging. After being used for 1 day, it will only takes 5 hours of direct sun to recharge the battery bank. When there hasn’t been enough sun hours to recharge the batteries, a traditional gas generator can be utilized to recharge the batteries and ensure 24-hour redundancy.

Battery Storage & Augmented Power Generation

  • Choose from Tubular Gell or the latest in Lithium battery technology
  • Add on a MOBIWIND 3kW Vertical Axis Wind Turbine to harvest wind energy during the day and night.
  • Add on stand-along solar array that can be connected to the MOBISUN for extra power especially in low-sun areas

Climate Control

Sensitive electronics and batteries can suffer from reduced life and performance well in extreme heat or cold. The MOBISUN system is built with high-efficiency heating and cooling units that will maintain the environment inside the trailer at the optimum operating temperatures. The sealed (HVAC) units also protect the more sensitive equipment from dust, sand and other small particles in the air since it does not mix the inside and outside air. Automatic switching along with monitoring overall performance remotely ensures that the MOBISUN will operate perfectly at any location and extreme environment thus ensuring optimized lifetime and  a predictable ROI.

Remote Monitoring & Control

Remotely configure and monitor the MOBISUN system through our Internet of Things (IoT) proprietary software, collects data and event logs, as well as graphical displays of historical and real-time energy harvest and power yield are easily reviewed over the internet using a Web browser or Android tablet device for easy performance analysis and troubleshooting – anywhere.

Patented Technology

Mobismart’s sophisticated design consists of several proprietary elements and manufacturing processes that are unique in this market today. Multiple unit manufacturing.


When more power and storage is necessary, MOBISUNs can be connected to create a micro-grid Alternatively, customized solutions – mobile or stationary – are available that use the same reliable electrical architecture for power conversion and power storage to support a wide range of uses and requirements.


Since all of the equipment used in the MOBISUN are all bankable from tier-one manufacturers, MOBISMART can arrange for low-rate leasing for any one of our models. If you need an OPEX option, we can setup a Power Purchase Agreements (PPA) to pay only for the power that is used.
