battery monitoring over ethernet

hello all,
i install remote wifi units,, being powered by 12v lead acid batteries (600amps) in all,,, i wish to be able to dial in (by means of an installed 3g router) and access some form of ethernet enabled volt meter- giving an indication of the battery level... tried looking on the net... cant seem to find anything... anyone come across such a product ?????

remote battery monitoring

There are of course LAN-enabled benchtop-multimeters, e.g. Agilent 34410A. But they are possibly too expensive and too accurate anyway.

Furthermore, there's a rich choice of PC data acquisition solutions, including analog measurement modules. They expose different interfaces, e.g. RS232/485, USB and Ethernet. See e.g. ADAM-6024 Ethernet-I/O-Modul from Advantech.

Finally, remote accessible data loggers, including e.g. GSM data communication, can provide the complete functionality in a box.

P.S.: An example for remote accessible data logger/alarm device using SMS communication http://www.gesytec.de/uk/produkte/gipsy/gsm-boxes/gipsy-lp/
