The operation of the router from an external power source, what can you advise?

Question

Batteries

Hello. There was a problem with the power supply of the routers. The routers will be installed at stops, will be connected to city lighting, which is available for a maximum of 10 hours. The remaining 14 hours the router will be without power. How can I get out of this situation so that the router works around the clock? Characteristics of the router 14 watts 0.8 amps 24 volts. Thanks in advance for your reply.

Answer 1

Discover PoE

Answer 2

The characteristics are somewhat strange 14 watts 0.8 amps 24 volts. Or is the amperage for the power supply specified?
Well, figs with them, we consider 14 watts * 14 hours = 196 watts / hours We consider the battery 196/24
= 8.9 That is, you need a 24v battery at least 10A / h.
Well, or two 12 volt batteries each at 20A / h.
To the batteries - a smart charger.
If you use lead-acid batteries, then do not forget that they can safely take no more than 50% of the capacity. That is, if you need 20a / h, then the battery must be at least 40a / h.
If not lead but lithium, then it is advisable to remember that lithium cannot be charged at low temperatures.
A little more confusing is the fact that you claim that there is power on the lighting line for 10 hours, but not 14 hours. Is this for summer or winter? There is a possibility that in the summer the power supply to the lighting line will be supplied for a shorter time.

Answer 3

Charger and 2 12-volt batteries 42 Ah, so that they last 10 hours in the cold.

Answer 4

What about solar panels? In some European cities I saw, incl. in those where there is no more sun than in Moscow. Reduce the power of the router.
In theory, they can recharge a lithium battery worth 10 bucks (in China), which may well be enough.
