Quattro 15000 277v not working on 50hz

[AndyK]

Hello, everyone! I need help. Quattro 15000 277v firmware 2799556 according to the instructions supports an input voltage with a frequency of 50 Hz, but it actually sees it, but does not turn on the charger, complains about low frequency and works in inverter mode. Tested on two inputs. I am trying to use it in Europe. The voltage is 237 volts. The output is only 60 Hz, which is fine with me. How can I make it accept 50 Hz at the input?

Switching the internal jumpers did not produce any results.

The firmware does not allow you to select or change the region.

Did you select a grid code in VE.config?
A grid code could prevent accepting a too low frequency.

Did you enable the option to accept a wide input frequency range?

grid code

The grid code does not allow changes. This option was the first thing that came to my mind too…))

So you did select a grid code or you don’t even have the option to select a grid code?
Maybe add a screenshot of your settings.
(I can only use VE.config to simulate a device with all options, so I might see options you don’t have)

In the “general” tab is there an option to switch the system frequency between 50Hz and 60Hz?
