I’m using an Anker PowerStation 767 as USV (without solar panel yet). I’m only using the AC output for my computer and my router - no DC outputs.
I live in Germany, and my company bought this device for me (to be able to work), because there are major doubts how fast our energy politics (nuclear phaseout without a good replacement plan and other problems) will lead to blackouts (or even scheduled loadshedding).
So the 767 seems to be a great device to be used as USV.
In Germany, there is much discussion about renewable energies including solar energy. If I already have a 767 - why not add a solar panel? Sadly, it seems that there is a small thing missing:
As I understand, it currently doesn’t make sense to attach a 767 to a solar panel and an AC plug at the same time, because I somewhere read that the 767 prefers AC over DC input - so it would only use the solar panel in the case of power outage - which doesn’t make sense.
I understand that there might be technical reasons which avoid using AC and DC for charging at the same time - but: shouldn’t it be possible to add a “Solar USV mode” with a firmware+app update which uses only the solar panel (DC input) for charging, and uses the AC input never for charging, but only under some conditions* enable the AC bypass?
- Think of having a (maybe configurable) upper and lower charge level limit:
When the charge level reaches (>=) the upper charge limit (e.g. 70% or 95%), disable the AC bypass so that the collected energy can be used.
When the charge level reaches (<=) the lower charge limit (e.g. 30%), enable the AC bypass - so that the 767 can use all available solar energy to charge itself (how long it ever might take)
In case of disappearing AC input, disable the AC bypass.
In case of restored AC input, enable the AC bypass always unless the current charge level is equal or above the upper charge limit.
