How I power Cisco Wireless Access Point (WAP4410N) Entirely off Solar System

---

This post will outline how to power wireless access point off solar system. Most networking devices already operate off 12V DC however sometimes batteries charged by solar can be over 12 Volts or Under 12V depending on the sunlight situation. Since the WAP4410N will work via ethernet injector or DC power supply, an inverter is not necessary to operate via battery bank.

My WAP4410N has been up for over 21 days purely powered off solar. The access point is plugged into a 12V DC stabilizer which is plugged into the load side of MPPT charge controller. Operating off the load side of the charge controller will protect my lead acid batteries from being discharged below 50%. The 12V DC stabilizer will ensure that the voltage going into the access point never exceeds 12 volts.

Should the batteries become lower than 50% the charge controller will shut the load off, there by preventing any additional discharge. The cost of lead acid batteries far exceed the cost of the access point so protection is key should there be an overcast day without much electricity production.

To make things plug and play male/female DC power jacks available on eBay come in super handy. I soldered DC jacks onto both ends of 30 ft of wire and to the input/output of the DC stabilizer and onto the load output of the charge controller. This makes it so it plugs directly into the charge controller. Super convenient should the need to plug into the grid should arise.
