Reliable monitoring connectivity for solar installations — without the customer’s WiFi
Solar installers across Ireland need dependable remote monitoring on every site. Relying on the customer’s broadband fails the moment they change provider or password. TITAN supplies a complete, independent cellular solution — router, antenna and low-cost IoT SIM — that installers can roll straight into their ongoing service.
Cable, WiFi bridge, or cellular?
If you’re still deciding how to connect your solar installations, our guide walks through all three approaches — and why most Irish installers land on independent cellular.

Everything an installer needs to deliver dependable monitoring on any site, packaged to fold into their service offering.
Industrial-grade cellular router
Built for 24/7 operation in harsh conditions, with remote management built in.
- Robustel R1510 — for Ethernet-only inverter and meter connections
- Robustel R1520 — adds Modbus for direct connection to inverters and meters
- DIN-rail or desk mount; external antenna options for weak-signal sites
- Compatible with every Irish operator — Vodafone, Three and Eir
Right-sized antenna
Signal varies dramatically site to site, so the antenna is matched to the location.
- Good coverage: Irish-tuned dipole antennas — reliable at lowest cost
- Moderate signal: Poynting PUCK-2 external antenna
- Remote / weak signal: Poynting XPOL-2 high-gain antenna
Low-cost IoT SIM
The monthly cost that puts installers off cellular — solved.
- Solar meter data is typically only megabytes per month
- Plans from €2/month — cost-competitive with any alternative
- Scale plans up or down as needs change; no overage surprises
- SIM and router managed together from one platform
Optional site survey
Remove the guesswork on coverage before you commit to a site.
- Professional cellular signal testing with the Siretta Snyper
- Confirms the right antenna tier from the start
- Recommended for larger or rural installations

Energy Expro, Irish solar installer
From hours of cabling to minutes of plug-and-play
Energy Expro needed to connect customer solar installations to the internet so both installer and customer could monitor performance and prove the value of the investment. Cable and WiFi-bridge approaches kept failing — ports were never near the controller, and monitoring dropped whenever a customer changed broadband.
The solution
An independent cellular connection built on the Robustel R1510/R1520, a tiered Poynting antenna strategy and a low-cost IoT SIM — a complete package they roll into their ongoing service.
The result
Installs that took hours of cable routing now take minutes. No drilling, no aesthetic compromises, and monitoring that stays online regardless of customer internet changes — all managed remotely without site visits.

Solar connectivity FAQ
How much data does solar monitoring actually use?
Very little — typically only megabytes per month. That’s why a low-cost IoT SIM from around €2/month is more than enough, and why 4G is the sensible choice over 5G.
Why not just use the customer’s WiFi?
Because it’s outside your control. When a customer changes broadband provider, upgrades their plan or resets their password, monitoring can drop offline without warning. An independent cellular connection keeps monitoring running no matter what.
What if the site has weak cellular coverage?
We match the antenna to the site — a tuned dipole for good coverage, a Poynting PUCK-2 for moderate signal, or a high-gain XPOL-2 for remote locations. A Siretta site survey can confirm the right choice before installation.
Can the router connect directly to the inverter or meter?
Yes. The Robustel R1520 supports Modbus for a direct connection to meters and inverters; the R1510 covers standard Ethernet-only connections.
Which mobile network does it use?
Whichever performs best at the site. The routers work with Vodafone, Three and Eir, so you can select the network with the strongest local coverage.
Does this only work for solar?
No. The same approach connects almost any remote device — environmental sensors, industrial equipment, water and utility meters, agricultural monitoring and more. Solar is simply where it’s most proven for us in Ireland.
Ready to add reliable monitoring to every install?
Whether you’re a solar installer or you need to connect any remote device, TITAN can put together the complete turnkey solution — including an optional on-site cellular survey.
