How about the Meanwell AD-155C? Or the Meanwell SDR-240-48+Traco BCMU360 which can use a single battery and output either 24VDC or 48VDC? Combine these with a PacketFlux SiteMonitor and not only do you have some monitoring (of voltage and temperature), but you can also be alerted about an AC power outage if you connect the contacts on the BCMU360 to the SiteMonitor's SWITCH input.
