I have a Multiplus 3000/35/16 inverter connected to a cerbo GX. I had not connected the temperature sensor and recently when i tried to connect this to the temperature terminal block on the inverter i immediately got an overload + low voltage blinking LED status on the inverter. Curiously as well the inverter output voltage shot to around 270V. When i disconnect the sensor everything goes back to normal. Any one experienced this and any solutions for this?
