To monitor my Photovoltaic standalone system, I use a Netgear router-modem MBRN3000 (bought 2012) and a 3G antenna MTE ZF190. It does work but from time to time the connection to the web is lost probably by 3G network failure, and not restablished. If I am around I just cut the power off and back on. But If I am away?
Of course I can have a timer to cut the power on and off every now and then; not very elegant!
Any better idea?
