Solar-Powered, GSM-Enabled Off-Grid Installation: Fuel Automation at Remote Sites
At remote construction and mining sites, electricity and internet are often unavailable. We explain how to install a fuel automation system that runs off-grid using solar power and GSM.
One of the most common objections to fuel automation is this: "There's no electricity or internet at our site, so the system won't work there." This is actually the easiest problem to solve. With solar power and GSM, fuel automation works at off-grid sites too. This guide covers how to carry out an off-grid installation at remote construction and mining sites.
Why is an off-grid installation necessary?
The common characteristic of remote sites is the absence of infrastructure:
- Grid electricity is either nonexistent or unreliable,
- Wired internet access is not possible,
- The site may be temporary; investing in permanent infrastructure makes no sense.
Under these conditions, a system that assumes constant electricity and internet won't work. The solution is to bring energy and communication into the system itself.
Energy: solar panel and battery
The field units are powered by a solar panel and battery. The energy generated during the day both runs the system and charges the battery; at night and in cloudy weather, the battery kicks in. This ensures uninterrupted operation even without grid electricity. Panel and battery capacity are sized according to the site's energy needs and sunlight conditions.
Communication: GSM and offline operation
Data is transmitted to the center over GSM (mobile network). The critical point is this: the system doesn't stop even if the connection is momentarily lost. Field units can operate offline; refueling and level data are stored locally and synchronized with the center once the connection returns. In other words, a brief loss of signal does not cause data loss.
Considerations during installation
- Energy sizing: The panel and battery are chosen for the worst-case scenario (consecutive cloudy days).
- Durable hardware: Equipment resistant to dust, moisture, and heat is used.
- Offline buffer: Local data storage capacity is set to cover any prolonged outages.
- Portability: At temporary sites, the unit is installed so it can be dismantled and moved once the project is finished.
Conclusion
The absence of electricity and internet is not an obstacle to fuel automation, but a design requirement that has already been solved. With solar-powered supply and GSM-based, offline-capable communication, every drop of fuel can be recorded even at the most remote site. Just because your site is off-grid doesn't mean you have to give up control.
