Main Off Grid site
Posted: Thu Dec 17, 2015 3:37 am
This is our busiest site, during peak we see over 400Mbps all with wind and solar and two WS-12-250 switches.
For Batteries we use eighteen 6volt GC2 (225 AH) hooked in series and parallel for a 12v bank and we us 4 100ah AGM 12v batteries. The AGM batteries are the towers primary bank and we use relays to remotely control switching between banks. The switching between banks is scripted to happen when voltage gets low on the AGMs and to switch back once voltage reaches a certain level or if the banks are receiving (charging) more current than the equipment is taking. We do this to minimize the ware on the GC2s and because the AGMs take the extreme cold here better than the FLA batteries.
For charging we have 4 evergreen electric 210w panels and a Skymax 400w wind generator. Fortunately for us this mountain top is quite windy most of the time.
The site is ran by two WS-12-250 switches and we utilize the power tab a lot for managing power load by scheduling and by voltage triggers. We have a Mikrotik RB1100 at the site for routing and a RB2011 as a backup (not pictured).
