Setting charging limit (AC300)

Product Discussion BLUETTI AC Series
1

Hi,
is there a way to set a charging limit (eg 80%)? All the electric vehicles have this possibility to spare the battery. I think this is a essential feature.

Hi @tobias77 , This setting can be applied to AC300.
You can select PV Priority UPS Mode or Customized UPS Mode in the Working Mode of the display to achieve the charging result you want.

@BLUETTI As far as i can see in PV Priority UPS Mode or Customized UPS Mode there is just a setting for the charging limit by electric net. The limit by pv is 100% and ist not adjustable.

Hi @tobias77 , Yes. Whichever setting PV charging is preferred.

But i would like to have a charging limit (maximum level) by PV as well to spare the battery

I agree: I would like this as well.

@BLUETTI I’ve just bought EP500pro, this is my first BLUETTI product and I’m very disappointed that it doesn’t have a feature to stop charging after achieving a set % of capacity (for example 80%).
Please add this feature.

@psolius Sorry, after confirming with the tech team, there will be no firmware upgrades for the EP500PRO as you mentioned. If this is unacceptable, you can contact customer service for return processing.

If I may, I’d like to point out that Bluetti units utilize LiFePO4 batteries that do not suffer from charging up to 100% as some other, classic Li-Ion cells do. So strictly speaking, limiting SoC to 80% to save battery life seems superflous.
