Thanks that is helpful. The Epmp / Eptp use 10 watts according to Cambiums documentation. 450’s in 3ghz use 15 watts according to the same documentation.

My one bit of advice is this. Plan for the future and if you can afford it, double or even triple your planned/available wattage capacity. You will thank yourself later when you need to put in a licensed link/ power hungry AP, or someone needs a point to point link that can only see your solar site. We started small and have had to upgrade 3 times at one solar site. On Tue, Apr 14, 2015 at 12:38 PM, Bill Prince <[email protected]> wrote: Do yourself a favor, and switch to watts. That way you don't have to worry about how you string your batteries together, because watts is watts. For example, if you have a 100 amp-hour battery at 12 volts, that is 1200 watt-hours. If you have 27 of them (again for example), you don't have to worry about series/parallel issues because 27*1200 watt-hours is the same regardless. Your 109 watts sounds high to me. What do each of the ePTP consume? Our PMP450 APs are typically using about 12 watts (I think they are rated more like 15 watts). I think an RB2011 is probably only about 6 or 8 watts. bp <part15sbs{at}gmail{dot}com> On 4/14/2015 10:09 AM, Brandon Yuchasz wrote: This is a new concept for me. We are in the process of planning and deploying three new sites. Like a lot in the WISP world they are remote.� I was wondering if you guys can point me at resources to start educating myself on this process and put together some numbers for cost. The sites themselves are fairly simple. The largest will be running three Eptp Force 110 backhauls. Two Epmp APs and two Cambium450�s. Microtik 2011 for the router / switch. Using GigSync Injectorts for the GPS and power.� The other two sites are the same but only one backhaul.� Being way up north the calculations I am using are for Duluth MN weather which should be fine. I am coming up with 109 watts for this main tower according to google and manufacture spec sheets (seems like a lot) .
