Dear all,
I am using a 48/10000 VA Quattro in a 3-phase configuration. Occasionally, it gives an overload alarm even though the load is not high. I checked the VRM graphs and found that, even when the AC input is normal (234V), the inverter output alone drops to 154V, triggering the overload alarm. The settings are ESS with 90% SOC, and I have a lead-gel 1200Ah/48V battery. There are 10kW solar panels with two 250/100 controllers.Here below i have attached the voltage drop image.Thanks in advance for your help.
