Background
Advancements in power grid technologies have made it possible for residential solar energy providers to sell excess energy to utility companies. Residential solar power systems need to process data from various devices that use a variety of protocols while reliably managing accounting, monitoring, and control tasks for electricity generation and billing.
Case
A residential solar power solution provider need an IIoT gateway to perform the aforementioned tasks. Wi-Fi was the primary connection option, while LTE support was required for redundancy to ensure accurate electricity generation and billing information. Since the data volume of the information is low, the provider also considered using LTE Cat. 1 for lower monthly data fees.
System Requirements
- Low power consumption to maximize the electricity output of the solar panel
- Wi-Fi and LTE communication redundancy ensures data accuracy for energy usage and billing
- LTE Cat. 1 support to balance data volume needs and monthly cellular data fees
- Open platform for application development
- Able to perform remote device management for easy maintenance
