Yeah I know wholesale solar is not the best price but if you are starting from zero they are very helpful and knowledgeable. You can for sure shop around. I just know Gino is probably in a crunch and needs to get something going and their website had a mostly complete package of what I'd tell him to buy. If you just buy panels, batteries and a charge controller you'll quickly learn that you need a lot more to make it safe to work on and monitor/manage. Also it'd help a lot if we had the load size in watts. But that probably varries by tower site quite a bit. I know Our smallest tower is around 100watts but our largest is over 1000watts. Lastly Gino if you need boots on the ground to install the solar (or wireless) I can probably be available after nov 2nd. -Sean On Wed, Oct 4, 2017 at 8:32 PM Chuck McCown <ch...@wbmfg.com<mailto:ch...@wbmfg.com>> wrote: Affordable solar can beat the price.

Hey Gino, Since you are probably limited by time i didn't want to hold things up while i dig up all the photos and schematics. so to get you started i'd suggest a system like this: https://www.wholesalesolar.com/1890130/wholesale-solar/complete-systems/1.04-kw-watt-telecom-off-grid-dc-24-48v we use this supplier a lot and they are great to work with and their prices are decent. they provide the schematics for how it all gets connected and if you get 5 hours of sunlight per day (which you should in PR even on Dec 21st) then this system will power a 200W tower just fine. if your tower uses 300W then just add 2 more panels (and another 30A breaker) and you can still use the same morning star 60A charge controller. If your tower uses more than 300W then keep adding panels, charge controllers and Batts. You'll need to add batteries, connecting cables and another 80A breaker (for battery cutoff) to this parts list. we use UB-4D AGM 200 ah 12 VDC Battery at our towers. we usually have 12 of them at a site but we are in CO and in December we will go for 2 weeks without any sun (I doubt you have that issue). you could probably get away with 4-8 of them per tower. the other item you want to add is this: http://store.packetflux.com/sitemonitor-interface-for-morningstar-serial/ and this: http://store.packetflux.com/sitemonitor-base-unit-ii/ the morning start controller does have an ethernet port but you can use SNMP to query the device and graph everything, you can only look at their stats page. it's much easier to do graphing and alerting with the packetflux devices. ***Be sure to fuse and breaker everything you can*** you want (and need) to be able to turn off all power coming from the panels or batts when you need to work on the system. (that's what the 80A breaker in the parts list is for.) for the load side of things you can use these fuse blocks. they use the car style blade fuses you can get at any parts store or order online.
