How does UPS mode work on the AC2P through DC power?
It seems to me that the station doesn’t have such a capability at all, since the load is connected, but there’s no power consumption from the grid. However, every few minutes, the station discharges to 99%, then charges to 100%, and disconnects from the grid.
Why is that?
I was planning to use 12V DC power to get a few extra hours, as using the inverter consumes more energy, but for some reason, this doesn’t work.
Can the station operate in this mode for an extended period of time?
Will this mode of operation affect the battery life cycles?
The Power gets passed thru, but the internals of the powerstation also consumes energy. Thats why it discharge to 99%. The Powerstation detect that loss of 1% and recharge it to the configured 100% SoC.
A full battery cycle means a full charge from 0% - 100% and discharge from 100% to 0%.
These powerstation are designed to operate as UPS, so dont see any issue with it to actual use it.
I mean something slightly different.
Why is there no pass-through charging mode, meaning direct power transfer from the DC input to the DC outputs or from the AC input to the DC outputs, bypassing the battery so that it is not involved?
I still can’t find information on how short charge cycles of 100-99-100% affect the battery’s condition.
In one response, it is stated that such behavior does not affect the battery’s lifespan:
While in another, it is mentioned that there is an impact:
The point is that on my station, one 100-99-100% cycle occurs every 20 minutes, which totals 72 cycles per day, and this raises concerns.
