Issue with 250/85 mppt

Hello

I have some questions regarding my mppt. Sometimes is creating some spikes every few minutes and I don’t understand why. Sometimes everything is fine.
I want to mention that the mppt have also cooling and the highest temp on full throttle is maximum 37°C.

Thanks



When the MPPT is not limited by battery it cycles through the voltage range once every 10 minutes to keep checking it is at the maximum power point. If it is limited by the what the battery can accept or the controllers max current limit then it does not need to do this.

Thank you for answering. Until around 1 pm the battery is on charging. Also always feeding to the grid. The spikes are when the battery is at 50%.
