I wonder if anyone can enlighten me a little about the Pmax reading i'm getting from my Victron connect app for smart solar? I have two solar panels fitted one new 150W panel and one that came with the van of unknown wattage but similar size to the new one, these were wired in parallel to a Victron 100/20 smart solar controller, the most Pmax reading i've had so far is 156w does this sound correct for real world conditions, the biggest yield so far has been 710Wh, thanks for any light you can shed on this .
