Yes it’s the same error as mentioned. My eb3a is on the newest firmware.
When plugged in it’s going down to 99% ever 30min
As @m.briney already said, this behavior unfortunately is part of the current design of the power stations. This is because the internal electronics always run from battery power when in UPS mode. So this discharges the battery to 99% and then the power station recharges it to 100%.
Traditional server UPS units run their internal electronics from either the utility power or battery so these don’t have this evergoing discharge/recharge cycle. Imo, this is a far more elegant solution and something the (solar) power station manufacturers should move towards.

Hi @Biospargel, I think it is a normal condition.
I agree with @TheQuickFox’s opinion. When the EB3A is fully charged, to avoid overcharging, the machine automatically stops charging and starts discharging. During this process, the battery level may drop to 99%, at which point it will begin charging again automatically until it reaches 100%.
During both charging and discharging, the internal temperature of the battery cells increases, causing the fan to automatically turn on for cooling purposes. Unfortunately, the fan cannot be manually turned off, nor can this be achieved through a firmware upgrade, as it depends on not only the load power but also the internal cell temperature and environmental conditions. We recommend placing the EB3A in a well-ventilated, cool area or using an external fan to help with cooling.

Ok thanks for your help. But is there any way to implement a charge limit like only charge to 80% to increase the lifespan of the lfp. Like on ecoflows. There you can easily set a charge limit. That would be so helpful. I use the eb3a as a ups for the night when I have no solar input. But over the day it’s so annoying.
Thanks for your time.
Hi @Biospargel, I appreciate your kind understanding and patience.
We completely understand your feelings. However, due to the limitations of the EB3A’s hardware, it’s difficult to develop new features for it.
Currently, the best option might be to use a smart plug to set charging times, ensuring that charging only occurs when needed.
We’ve collected your feedback and have passed it on to our R&D department. We hope that future models will be able to incorporate this feature.
