Reliable Power with Less Generator Runtime
Traditional diesel generators frequently run for long periods, even when the connected load is relatively low. This results in unnecessary fuel consumption, noise, maintenance and refuelling logistics. A Mobisun hybrid solar power system follows a battery-first energy strategy.
How the battery-first strategy works
- Solar panels supply the active electrical loads.
- Surplus solar energy charges the integrated battery.
- Stored energy powers equipment when solar production is low or unavailable.
- The back-up generator supports the system only when demand exceeds the available solar and battery capacity.
This approach can significantly reduce unnecessary generator operating hours while maintaining the resilience required for professional applications. Mobisun typically recommends a 10 kVA back-up for the Solar Trailer, 20 kVA for the 20ft Container and 40 kVA for the 40ft Container.
Built for Professional Applications

Construction Sites
Power for site cabins, lighting, access control, Wi-Fi, security cameras, charging equipment, pumps and appropriately sized electrical tools before a permanent grid connection is available.
Solar energy for construction sites →Telecom and Remote Monitoring
Support telecom towers, network equipment, cameras, sensors, PoE devices and communications infrastructure at remote or difficult-to-access locations.
Power for cell towers →Emergency and Humanitarian Response
Rapidly establish power for communications, lighting, field coordination, water systems, temporary accommodation and other essential equipment.
Disaster response energy → Humanitarian aid →Events and Hospitality
Supply quieter battery power for lighting, communications, audiovisual systems, temporary facilities and guest services.
Resorts and hospitality solar →Remote Infrastructure and Microgrids
Create a local energy supply for agriculture, water treatment, remote communities, industrial operations and locations where extending the electricity grid is impractical.
Discuss your project →Business Continuity and Backup Power
Support selected critical loads during grid outages or at sites with an unreliable electricity connection.
Backup power solutions →Designed Around Your Energy Profile
Choosing an off-grid energy system requires more than comparing battery capacity and solar wattage. Mobisun assesses the complete operating profile, including:
- Average continuous power consumption
- Short-duration peak loads
- Daily operating hours
- Required autonomy
- Single-phase or three-phase equipment
- Seasonal solar availability
- Location and climate
- Available installation area
- Grid and generator availability
- Transport and deployment requirements
- Remote monitoring requirements
- Future expansion plans
This prevents an undersized system from interrupting operations and avoids unnecessarily oversizing the project.

Frequently Asked Questions
What is a containerized solar power system?
A containerized solar power system combines solar panels, battery storage, inverters, electrical distribution, monitoring and, where required, back-up generation in or around a transportable container platform. It can provide electricity independently of the public grid or work as part of a hybrid or microgrid installation.
What is the difference between the three Mobisun systems?
The Solar Trailer is the most mobile solution and is suited to temporary projects. The 20ft Solar Container offers greater storage and output for medium-scale sites. The 40ft Solar Container provides the highest capacity for larger infrastructure and microgrid applications.
Can a Mobisun system completely replace a diesel generator?
In some projects, sufficient solar generation and battery capacity can eliminate the need for regular generator use. In other situations, a generator remains useful for exceptional peak loads, poor weather or additional resilience. The correct configuration depends on the project’s load profile, season, location and required uptime.
Do the systems supply power at night?
Yes. Electricity generated during daylight hours can be stored in the battery and used at night. The achievable runtime depends on battery capacity, the connected load and the energy produced during the day.
Can the battery and solar capacity be customized?
Project-specific adaptations may be possible. The final configuration is determined by the required power, daily energy consumption, autonomy, location, transport restrictions and available installation area.
Are the systems suitable for outdoor deployment?
The systems are designed for professional outdoor deployment. The required environmental protection, temperature range, ventilation, foundation and climate adaptations should be confirmed for each project.
Can the systems be monitored remotely?
Yes. The current systems support remote monitoring and control, providing insight into generation, consumption, battery status and overall system performance.
Are rental and lease options available?
Rental and lease options may be available depending on the system and project. The Solar Trailer is particularly suitable for temporary rental deployments. Availability, transportation and service conditions are confirmed in the quotation.
What information is needed for a quotation?
For an accurate recommendation, provide the project location, an equipment and appliance list, continuous and peak power requirements, operating hours per day, the required operating period, single-phase or three-phase requirements, desired autonomy, available installation space, preferred delivery date and grid or generator availability.
