IoT for solar PV systems
The solar business case is changing. It is no longer only about producing kilowatt hours for self consumption, but increasingly about smart control and participation in grid services and frequency response markets. These opportunities are growing fast, but joining them takes more than panels on a roof. You need connectivity that is as reliable as sunrise. Too many operators still connect inverters to existing Wi-Fi, a setup that might be fine for small scale use, but can quickly translate into lost revenue when uptime and response times matter.
Grid services demand millisecond response times
Selling grid services means your solar PV and battery storage help the power system stay balanced. This happens automatically, but response time requirements are strict. If your Wi-Fi becomes unstable or the office router reboots, you lose connectivity. Then you cannot deliver the service and you miss out on revenue.
With Advisera’s industrial IoT SIMs, you remove that risk. Our SIMs connect your inverter and battery storage directly to the mobile network, independent of the site’s local IT environment. This delivers the low latency and high availability required for certified participation in grid services and frequency response programs.
Full visibility with Cisco IoT Control Center
Operating a solar park or multiple rooftop sites across different locations makes uptime monitoring a real challenge. With Cisco IoT Control Center, you get a single view of connectivity across all installations. The same tooling used by large energy players, available to operators with five sites or five hundred.
- Real time monitoring: Instantly see if a site loses connectivity and act before it impacts performance.
- Security: Energy assets are critical infrastructure. Private connectivity options such as VPN keep inverters and controllers off the public internet.
- Cost control: Set data caps and alerts so you never get surprised if a device starts pulling large firmware updates or misbehaves.
Multi network roaming for maximum uptime
Solar PV is often installed on rooftops, in fields, or in remote areas where coverage varies. A standard mobile subscription is tied to one carrier. Our IoT SIMs are carrier independent and support multi network roaming. That means the SIM in your inverter automatically connects to the strongest available network at each site. This is your insurance against local outages and weak coverage.
Frequently asked questions about connected solar PV (FAQ)
Why should I not use Wi-Fi for the inverter?
Wi-Fi often suffers from range limitations and depends on local routers and IT changes. During power outages, Wi-Fi equipment may fail immediately. A mobile 4G or 5G connection is typically more resilient and separated from the site’s office network.
Do your SIMs work with my battery storage system?
Yes. Our IoT SIMs follow M2M standards and work with most equipment that supports mobile connectivity, including common inverter and storage ecosystems.
Is it difficult to install?
No. SIMs are delivered activated and ready to use. Insert the SIM into your router or gateway, and the device appears in the Cisco portal where you get full visibility and control.
