FAQ

Divide the capacity of the external battery by the power consumption of the central panel.

Power consumption of the central panel depends mostly on active communication modules — the average values ​​are indicated in the table:

Central panelActive communication modulesAverage input current
HubGSM42 mA
Ethernet80 mA
GSM+Ethernet90 mA
Hub PlusGSM35 mA
Ethernet72 mA
GSM+Ethernet93 mA

For instance, when connected to a 40A·h battery, Hub 2 — with active GSM module only — will operate approximately 1200 hours (40A·h / 0.033A).
