Pre-packaged 24VDC Solar System

Which two system holds up power 24VDC to 24 hours a day for at least 5 days in the event of no charge days- one of which is rated at 8.5 watts and another at 8.0watts allowing 10% wiggle room? In addition to that, that system should provide contact closures or something similar that tells us the battery is not charging or the battery is running low?

It varies depending on the location of the Solar/PV’s systems City/zip code. The duty cycle of your loads also varies or should we assume that the loads will be drawing currently 24X7? For the diagnostics of battery it depends if you need something on site or some sort of remote diagnostics
Yes we are running 24/7. We got a PLC in the box which will be reading two 4-20ma 2-wire transmitters, which the solar must also power, but their consumption is negligible in comparison to the PLC and the telemetry transmitter. If we can get charging state and low battery warning states into the PLC via a discrete input or similar, we will then transmit that data back to the operator via the elementary system
We don’t stock any programmable battery monitors that output digital levels that can be fed into a PLC so we have to check if we can source this. We do stock full battery monitors but these have integrated comm to serial or wireless which would be unnecessary for you. One option would be to wire up an LVD or a solar charge controller with a circuit that could generate the appropriate voltage level for the PLC input rather than disconnect/ connect the load but I suspect there must be a more elegant solution which is what we are researching. The thing is this can be done we just need to figure out the best approach.

Do you have remote battery monitors with integrated com to serious wireless?

Also remember due to your requirements of 5 no-sun-days you will need a larger capacity battery bank than the one specified. This http://www.rfwel.com/shop/Pre-packag...ar-System.html is an 80W, 24VDC, 99AH system.
