Unfortunately the mountain tops needed for good coverage are to far away from utility power to justify the construction cost of power lines.
Our trial site consists of of 6 rockets, 3 NBM5, and a mikrotik AC, about 80watts in total.
We have two battery banks which consist of two 12v AGM batteries, and eight GC2 6v batteries. We run 12volt banks, and for a couple of reasons. 1) it is much easier to find auto style parts and accessories if needed. 2) if we should have a power issue we can jump and charge the bank from a truck.
For charging we have 430 watts of solar and a 400watt 3 phase wind turbine.
Now keep in mind we're in Wyoming where during the winter we have a couple of months with average highs around 35f and lows at night are possible to the -30s and about 7 hours of good sun light. We also get a fair amount of wind. Honestly I get more from the wind then the sun.
The charge controller we use has a divert load resister (basically a heating coil). The plus side to that is when the banks are charged we generate some heat from the excess power. This helps keep the building warmer. It rarely drops below freezing inside the building. In the last two years we haven't had the inside temperature of the building drop below 20f, that was on a real cold night about -32 after a long week of highs not above 10f.
The battery banks, this is where we get creative. We use a RB750UP as an automation controller. I've wrote several scripts that control different functions.
We use a pair of relays (redundant) that allows us the RB to switch between the two banks. We use the AGM bank 90% of the time, and when the voltage on that bank gets low the RB automatically switches the load to the GC2 bank. Once we start charging and the voltage reaches a certain point (near full charge) we switch the load back to the AGM bank. The AGM batteries are much more durable then the G2 but they lack the true deep-cycle of the GC2s. By using the AGMs for the daily cycling and reserving the GC2s for the extended use we extend battery life a great deal and minimize maintenance.
We have another relay setup that allows us to remotely feather the wind turbine.
We also use the RB to power off our second backhaul during non-peak hours. But we're able to build some logic into the process and only turn it off if we're running on the 2nd battery bank and it automatically restarts it if traffic reaches certain thresholds.
We also use the RB to remotely activate a tower locate strobe. This was added to help the installers find the tower after sundown or during fog or poor visibility. Of corse we could do this with any poe port, but that's what the RB was intended for
I thought I'd share that because I'm curious to know if anyone else does anything similar.
Not sure BLM would go for that, but i love the suggestion.
