Centralised solar farm connectivity with Instaroute
One managed network for inverters, meters and cameras across solar farms, run from a single console.
The challenge
A solar portfolio grows plant by plant, often with different inverter makes and a different link at each site. Monitoring ends up split across tools, and nobody sees the whole fleet.
Inverter makers also need remote access for support, which should not mean opening the plant network to the internet.
How Nexapp solved it
One console for every site
Instaroute SDWAN Lite 2.0 shows the health, signal and data usage of every router, with zero-touch set-up and canary firmware rollout, wave by wave.
Speaks the site's protocols
RS232/RS485 serial ports, a Modbus RTU/ASCII/TCP gateway, DNP3, IEC 60870-5-101/104 and MQTT, so existing controllers and meters connect without replacement.
Cellular links that stay up
Instaroute 4G and 5G routers with dual-SIM failover between two operators, and outdoor IP65 units that mount where the signal is best.
Vendor access without open ports
Engineers and equipment vendors connect through the InstaAccess client (ZTNA, SSL VPN or IPsec VPN) to only the equipment they support, and every session is logged.
What changed
- Every plant's generation data reaches one monitoring system.
- Router health and data usage are visible for the whole portfolio.
- Inverter vendors get scoped, logged access.

A Nexapp engineer can walk you through this deployment and map it to your own sites, links and devices.
