Use cases
IoT SIM cards for energy, solar, and EV charging
Solar inverters, battery systems, generators, and chargers that report production and take payment.
Energy equipment is installed wherever there is sun, wind, a load, or a parking space. A solar inverter reports its production, a battery reports its state, and a vehicle charger must authorize a driver and take payment. A charger that is offline cannot be used, and an inverter that is offline cannot report a fault. A Sturdy SIM gives each of them more than one network to rely on.
Where a Sturdy SIM is used in energy, solar, and EV charging
- Solar inverter and battery monitoring
- Electric vehicle charger authorization and payment
- Generator and fuel tank monitoring
- Oil, gas, and pipeline telemetry
