NR5103E input power range. Using Solar & Battery to power the router

jwkong

Hi, my house are using solar panels with batteries for power generation.

Can i know what is the NR5103E max input power range?

Is it from 10.0v to 14.4v or how?

i am planning to use the 12v battery to power the- 5G router but using a solar to charge the battery the power output of the battery will float from 11.0v (used) to 14.4v (fully charging).

This will provide voltage from 11v to 14.4v throughtout 24 hr a day.

thanks

Hi,

Upto 48W power consumption.

So 4 amps at 12v , see

But I haven't been able to find the max input voltage.

Hello @jwkong

It talks there about using a 12v 4A Gigabit Power over Ethernet (PoE) device to power the NR5103E.

You could use the solar cells to power an inverter to convert DC to AC, and then use an AC powered PoE with a 12v 4A output to power the NR5103E…

I hope that this is helpful. Please let us know what you think.

Kind regards,

Tony

Thanks Tony for the help.

Yeah, i cant seems to find the nominal voltage range for the NR5103E router.

The last suggestion and post is indeed applicable but i am already using 12v DC from the solar.

So was thinking it will be best if i can use 12v DC directly into the router.

one issue with the inverter method of DC-AC-DC will be loss of energy and unreliable power output since the inverter im using is not pure sine wave.

Thats why i try not to use the inverter for small power appliances like this.
cos the output power from a direct DC is smaller and more simple.

Is there anyone from Zyxel technical or design team here who can share the design spec for the power input voltage range?

I really hope to be able to use the solar and battery for the router.
My solar + battery range from 10.7v to 14.4v max.

i am just afraid if the spec is low then it could burn the chip then i have to waste to buy another one.

thanks Tony for the advice and help.
