Decrease the charge power of a smart UPS SRT

[Anonymous user]

Hi,

My power budget is not looking too good because of the power that I estimate will be drawn by the smart UPS to recharge depleted batteries.

At the moment I am using the following numbers for the smart UPS SRT 10000VA:

• Integrated battery is 1000Wh and takes 1.5h to recharge
• Each battery pack is 1920Wh and takes 2.5h to recharge

Assuming a charge efficiency of 0.8, the power drawn is over 1.7kW average. Is there a way to decrease that power draw by trading off recharge time?

Thank you in advance,

Kind regards

I don't know of a way or a setting to change this on any type of Smart-UPS unfortunately.. I have not encountered any single phase UPS that allows you to modify how the charger operates or when the UPS will charge.
