Watt display blinks

Is it normal that the pv display changes between 0 and the watt as long as a small panel with 120 is connected?

Hi @Tinkerpete , One 120W solar panel is not enough to charge the EP500/EP500Pro with PV. It will flicker because the open circuit voltage does not reach the charging requirement.
We recommend you to connect at least three solar panels in series.

Ok, I have since done and indeed the change between 0 and one watt value has now disappeared. Thanks for the answer.
