Hello,
I will be setting up some Omnitiks on some city blocks. I want to use solar energy to have this Omnitiks up and running all the time so I don't have the issue of electrical outage. I did a search and found this:
Powering
The board accepts powering from the Ethernet port (Passive PoE):
• Ethernet port accepts passive Power over Ethernet 8-30VDC. Package contains a 24V adapter and a PoE injector.
Maximum power consumption of the device is 9W.

I also found this about solar energy:
http://www.recgroup.com/en/aboutsolar/b ... lar-maths/
Electrical energy is generally measured in kilowatt-hours (kWh). If a solar panel produces 100 watts for 1 hour, it has produced 100 watt-hours or 0.1 kWh.
In areas with high irradiation, a properly oriented panel that produces 100 Watts at noon on a sunny day will produce an average of about 0.5 kWh/day during the winter and 0.8 kWh/day during the summer months.
In an area with low irradiation, the same panel will still produce about 0.25 kWh/day during the winter and 0.6 kWh/day during summer months.
I am going to do this in Central America, we have lots of sun. So from reading this, I understand that a 100 watt Solar Panel can produce me 500 watts per day. Also from reading the Omnitik specs it only consumes 9 watts per hour.
So my question is the following, Does this mean that if I have a 100 watts panel that produces 500kwh per day and the Omnitik consumes only 9watt hours I would have 55 hours of electricity? What about the battery?
On another post someone said not to use an inverter. So how would I connect the POE?
Basically if someone know about this or already have an Omnitik setup with solar energy, can you guide me?
Thanks
