I’ve been searching the forum for recent examples of setups that use the Meteobridge Pro2 with a cellular modem, all powered by battery with solar. I’m looking to set up a wireless Davis Vantage Pro2 with my MBPro2 and have it transmit via LTE/4G. Are the dongle-type modems/routers preferable to stand-alone units? What sort of power setups are people using? What’s the minimum battery/solar requirements (I’m at ~50N latitude). I’d love to see what people have out there!

Yes anything is possible.

In conjunction with VP2 I use standalone 2 port routers with RMS capability which allows connection and control of an MBPro2 & Davis Envoy/WLIP which provide long term data redundancy in the event of any power or comms issues. Even though the MB2 can be conected via MB servers the router connection allows a few other functions. MB uploads to several sites and logs 1 minute data 24/7 with FTP upload, Envoy uploads to WeatherLink.com but also connects via WeatherLinkPC & VPN.

The system has multiple LVD units which disconnect devices based on battery voltages in order of least importance. There are 2 standard ISS units (station runs 2 anemometers) with primary DC power via 12/5 volt converters with external 2xD cell battery backup. Both iSS units will run for years on backup alone.

On this particular remote (island) station power is from 2 independent solar systems, 2x50 watt panels through a split regulator which maintains a 100Ah backup battery @ 10% charge and a separate 80Ah operational battery @ 90% charge. The second solar system is a 50 watt panel, single regular (with LVD) and 80Ah battery. That's more than enough power but is designed to run for quite some time at varying levels of operation. BTW the 100Ah is purely a last ditch backup if all else fails after the LVD's have disconnected power to less critical units but have never had this happen in over 20 years.

Obviously the WLIP is no longer available but run time could be extended even further using an Envoy & Serial data logger via a Moxa/TCPIP and for this purpose the dongle-type modems are basically useless but again solely depends on exactly what your design/operational parameters are? The stand-alone modem in the above setup allows switching (via VPN) of anemometers (for redundancy) between MB and/or Envoy but again depends on what redundancy is required. In this setup the Envoy is the primary logging device, the MB does the nice additional stuff.

There is a few other combinations but depends on what redundancy is required.

I used to run a station at the model airplane field.

Mini laptop with cell system data stick (USB).

120 watts of solar panels running into a 24 volt 50ah battery bank. (Laptop needed 19 volts, used a buck converter).

Normally had tons of power. Had to be 3 or 4 days of solid rain to run out.

Now that I know about and use WiFi Logger, it would be even easier if you could send through a router with cell data and skip the laptop.

That's exactly what I'm looking for... but for North America.
