Good afternoon, I would like to know if there is a possibility to update the firmware of this model, I have a 24v, 1000w installation on plates and NICad batteries 185Ah C5, and the problem is that these batteries need a lot of voltage you need to reach 1.90v per cell and the inverter is limited to 31.5v, so the 20 glasses only reach 1.57v.
Firmware----- U2-02 -----U1 29
What I need would be to remove the voltage rise limitation and reach at least 37-38v
thanks
