Is it possible to power-limit a Galaxy VS 50 kW UPS to operate safely on a 30 kW electrical infrastructure?

[Gregory_Jimenez]

Hello everyone,

I am looking for some technical advice or possible workarounds regarding an installation issue with a Galaxy VS UPS.

The Context: We originally quoted and ordered a 30 kW Galaxy VS UPS (GVSUPS30KB4GS). However, due to a shipping error, we received the 50 kW model (GVSUPS50KB4GS).

The Problem: The electrical infrastructure at the site—including piping, AWG wiring, and 60A breakers—is already fully installed and dimensioned specifically for the maximum input current of the 30 kW unit. According to the installation manual, the 50 kW UPS requires 100A breakers and a larger wire gauge (AWG 3/2).

It is important to note that the actual critical load connected to the UPS will remain exactly the same as originally planned, well within the 30 kW capacity.

My Question: Is there any official way to configure, power-limit, or restrict the 50 kW UPS via software/firmware (for example, limiting the battery charging current or capping the maximum input power) so that it can safely operate on the existing 60A infrastructure without risking tripping the breaker?

Replacing the UPS entirely (waiting for the correct 30 kW model) or replacing the newly installed wiring and breakers would cause a considerable delay and severely impact the end customer's timeline.

Has anyone faced a similar situation or can confirm if Schneider Electric supports a software-level limitation for this scenario?

Thank you in advance for your support and technical guidance.

Code would dictate that everything must match from supply, protection, to connected load.

If we ignore the above for a moment the reality is this is like any high output device. You can have a very powerful generator but nothing impacts you from using less power than the unit can provide and sustain.

If everything is taken at face value as to the current installation the breaker will trip and never allow you to draw more than 60 amps from the service panel.
