PV maintenance and operation management

Scalable VPN server and robust cellular routers

“We’ve acquired a large housing society as maintenance customer. Different routers have been installed there, which have transmitted data very unreliable. We are retrofitting these plants with EBW-H100 cellular routers at the moment and I have to say that the INSYS routers are running perfectly.“
