January 7Jan 7 Hello, I have the following problem with the inverter presented above: it does not correctly display the current from the photovoltaic panels and implicitly the production is calculated incorrectly. I would need a diagram of the MPPT to see where the current transformers or sensors that do this are. I think it is a sensor problem and I do not know what they are. Thank you

Thank youCould you perhaps share the volts, amps and power that the inverter shows and what you have measured for volts and amps for the PV strings you have connected to the said inverter?
January 7Jan 7 Hello,The voltage from the panels is displayed correctly in volts, but the current measured with an ammeter inserted into the panels or with a DC ammeter clamp is about 50% lower than that displayed by the inverter. It is cloudy now and I don't really have any measurements because there is no production. I also use Solar Asistant and there is the real charging current given by the BMS which is connected to Solar Asistant. I am also attaching some more conclusive pictures of what the inverter looks like and what I physically measure. I am looking for a double MPPT electrical diagram if anyone has one.Thank you.
