Alas, although some of these units advertise this capability, they don’t reliably operate this way. I’ve tried several brands as solar-charged UPSes at remote radio antenna sites, and all eventually failed within just a couple months of the batteries didn’t make it through a long gray spell.
In my experience, they may initially work as a UPS for a few power outage cycles, but then suddenly fail permanently with burned components. Some vendors actually say operating as a UPS — drawing power while charging — voids the warranty, despite appearing to work.
Interesting, thanks for your feedback. Also overhead of 41W sounds like a feal breaker. BR, ic
